We are given the information that the equation of the line is of the form:

y = a x + b

where a is a negative number and b is a positive number.

And we are asked to select among a number of options that represent the situation.

SInce b is a positive number (being "b" what is understood as the y-intercept) the line DOESN'T pass through the origing of coordinates. So the first option is discarded.

SInce "a"is a negative number (this is the so called "slope' of the line) the line must be slanted, and **dropping** from left to right Therefore option b is also discarded because that represents a line going up from left to right.

Option c is also discarded, because a is a negative number (not a zero) and lines parallel to the x axis have slope zero.

The last option is the correct one, since the intercept oo the y-axis is at a positive value for y, the line must be going down due to the negative slope, and therefore going across the II, I and IV quadrant as shown below: (give me a few minutes to draw a line with this characteristics)

Then, please mark the **last option (d) **as the correct answer.

a) Rotation, then reflectionb) Reflection, then rotation c) Reflection, then translationd) Rotation, then translation

The first transformation applied to the pre image is a reflection.

The second transformation applied is a 270° rotation.

It means the right answer is Reflection, then rotation.

Graph the linear function f(x)=4x+1 by plotting points.

To plot points, click on a point on the graph and drag it to the desired location.

A **graph** of the **linear function** (f(x) = 4x + 1) is shown in the image attached below.

A **graph** is a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the **x-axis **and** y-axis**.

Generally speaking, the **graph** of any proportional relationship such as a **linear function** is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the** x-axis** increases or decreases, the values on the** y-axis** increases or decreases simultaneously as shown in the image attached below.

The graph shows a coordinate plane that goes from negative 8 to 8 in each direction. The graph also shows two lines that intersect at ( 2 , 3 ). That point is labeled "solution." That's right. When you have two or more linear equations, it is called a "system of linear equations". The solution to a system of linear equations consists of the - and -value that make BOTH equations true. Graphically, this appears as the point where the lines intersect. In this case, the solution is the ordered pair , as shown on the graph. If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?

To visualize the **solution **of a **system of equations,** a **graph **is ideal, as we can see whether the functions intersect or not.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the context of the problem. The pair/tuple/... containing these values is called the **solution **of the system.

The equations that construct a system are **functions**, and the **solution **of a system is at the point of **intersection **of these functions. The intersection of two points is easier to visualize graphically then calculating, hence a **graph **is ideal, as we can see whether the functions intersect or not, while for the function we would have to calculate.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third

side is 13 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet.

**Answer:**

The triangle has sides of **36 feet, 72 feet, and 49 feet.**

=====================================================

x = shortest side

2x = second side

x+13 = third side

The three sides add up to the perimeter of 157

(x)+(2x)+(x+13) = 157

4x+13 = 157

4x = 157-13

4x = 144

x = 144/4

x = 36

The shortest side is 36 feet.

The second side is 2x = 2*36 = 72 feet.

The third side is x+13 = 36+13 = 49 feet.

Check:

side1+side2+side3 = 36+72+49 = 157

I need help with this worksheet that’s due tomorrow for algebra 1 it’s about Characteristics of Quadratic Functions

We have the following quadratic Function in a graph:

Now, we solve one aspect at a time:

**Zeros**

Let's remember that the zeros or roots of the quadratic function are those values of x for which the expression is 0. Graphically, the roots correspond to the abscissae of the points where the parabola intersects the x-axis.

By looking at the graph we can identify these, which in this case it is:

[tex](-2,0)[/tex]**Axis of symmetry**

Recall that the graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola.

By looking at the graph we can identify this, which in this case it is:

[tex]x=-2[/tex]**Max or min**

In mathematical analysis, the maxima and minima of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range or on the entire domain.

By looking at the graph we can identify this, which in this case it is:

[tex]y=0[/tex]**Vertex**

Remember that the vertex of a quadratic equation or parabola is the highest or lowest point of the graph corresponding to that function. The vertex lies in the plane of symmetry of the parabola; whatever happens to the left of this point will be an exact reflection of what happens to the right.

By looking at the graph we can identify this, which in this case it is:

Human hair grows at a rate of about 6.849×10-4 cm per hour to 2.329×10−2 cm per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation rounding to 2 decimal places.

**Answer:**

2.×10^-2 cm/h . . . . rounded to 2 dp

2.26×10^-2 cm/h . . . . rounded to 3 sf

**Step-by-step explanation:**

You want the **difference** in growth rates **between 6.849×10^-4** cm per hour and **2.329×10^-2** cm per hour.

The difference of two numbers written in scientific notation requires that they have the same power-of-ten multiplier.

2.329×10^-2 - 6.849×10^-4

= 2.329×10^-2 - 0.06849×10^-2 = 2.26051×10^-2 = 0.0226051

RoundingThe question asks for the answer rounded to 2 decimal places and expressed in scientific notation.

0.0226051 ≈ 0.02 = **2×10^-2 . . . . cm per hour**

It makes more sense to round the *mantissa* to 2 decimal places, meaning the value is rounded to *3 significant figures*.

In triangle ABC, the segments drawn from the vertices intersect at point G. Segment FG measures 6 cm, and segment FC measures 18 cm. Which best explains whether point G can be the centroid? (are the answers given here right? cos I'm not quite sure)

A centroid divides each median in a ratio 2:1, in this case, the segment FC is the sum of the segments FG and GC:

[tex]FC=FG+GC[/tex]By solving for GC, we get:

[tex]GC=FC-FG=18-6=12[/tex]Then, the part of the median that goes from C to G has a length of 12 and the part that goes from the centroid to F has a length of 6, then we can express their ratio as 12:6, which is equivalent to 2:1.

Then the answer is:

The value of the length AB xcm = -3½ which is derived using the **completing** the square method, and satisfies the expression 2x² - 5x - 42 = 0.

To solve for the unknown value of a **quadratic** equation; say ax² + bx + c = 0:

From the derived **quadratic** equation, applying the method of **completing** the square as follows;

2x² - 5x - 42 = 0

divide through by 2

x² - (5/2)x - 21 = 0

add 21 to both sides

x² - (5/2)x = 21

divide the coefficient of x, square the result and add it to both sides

x² - (5/2)x + (5/4)(5/4) = 21 + (5/4)(5/4)

factor the left hand side of the equation

(x - 5/4)² = 21 + (25/16)

simplify the right hand side

(x - 5/4)² = 361/16

take the square root of both sides

x - 5/4 = (+ or -)(19/4)

then;

x = 5/4 + 19/4 or 5/4 - 19/4

x = 3 or x = -3½

The **quadratic** equation 2x² - 5x - 42 = 0 is true for the value of x = -3½.

===========================================================

Explanation:

Define these two events

A = father born in Michigan

B = mother born in Michigan

The notation ~A and ~B represent the opposite of each defined event above.

According to the table

P(A) = 0.48

P(B) = 0.73

If A and B were independent, then P(A and B) = P(A)*P(B) = 0.48*0.73 = 0.3504 = 35.04% but this contradicts the 29% in the "father born in Michigan" column and "mother born in Michigan" row. The table states that P(A and B) = 0.29 should be the case instead of 0.3504.

Because of this contradiction, this means P(A and B) = P(A)*P(B) is false and therefore A and B are **NOT independent**

--------------------------------------

Another way to look at it:

P(A) = 0.48

P(A given B) = P(A and B)/P(B)

P(A given B) = 0.29/0.73

P(A given B) = 0.39726 approximately

If A and B were independent, then P(A) and P(A given B) would be the same value. However, they are not. This is another way to see why the events are **NOT independent**

Through similar calculations, P(B given A) = P(A and B)/P(A) = 0.29/0.48 = 0.6042 approximately which doesn't match with P(B) = 0.73; if A and B were independent then P(B) needs to be equal to P(B given A).
