Answer:

A   see  picture

Step-by-step explanation:

The given function: B. has the same slope and a different y-intercept.

The linear function is expressed in slope-intercept form as, y = mx + b, where b is the y-intercept and m is the slope.

Slope (m) of the first function is: -7/9.

Its y-intercept (b) is: 3.

Given the equation, y + 11 = -7/9x - 18, rewrite in slope-intercept form:

y + 11 = -7/9x - 18

y = -7/9x - 18 - 11

y = -7/9x - 29

The slope (m) is: -7/9

Its y-intercept (b) is: -29

Therefore: B. It has the same slope and a different y-intercept.

The x-intercepts of the given quadratic function are -2 and 9.

What is a quadratic function?

A quadratic function is a function represented as, f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabolic curve represents the graph of a quadratic function.

A polynomial's highest degree reveals how many roots the polynomial has. The values for which the polynomial's numerical value is equal to zero are known as a polynomial's roots (also known as zeros of a polynomial). On a graph, the points where the polynomial's graph and the x-axis cross are the roots (x-intercepts).

Roots of the Quadratic Equation

Due to its degree of 2, a quadratic function can only have a maximum of two real roots. In order to find the roots of a quadratic equation, we equate its factors to 0. Thus, in this case, we have,

(x+2)*(x-9)=0

∴ x+2=0

⇒ x=-2

Similarly,

x-9=0

⇒ x=9

Hence, the x- intercepts of the given quadratic function come out to be -2 and 9.

A line plot can be used as a data display for the distribution of test scores in math class. Thus, the option to choose is TRUE.

A line plot is a graph that shows data as checkmarks or dots across a number line, indicating the frequency of each value.

The test score in the math test will be discrete data with repeating frequencies. The score of every individual will moreover be a whole number.

The line plot, as we know, marks the dots across the number line, indicating frequency.

Thus, the scores in the math test can be displayed using a line plot, by indicating each type of mark on the line, and dots above those marks for the number of times the same marks occur.

The graph that shows the solution to the system of equations is attached below.

The solution to a system of linear equations is the point where the two graphs intersect. The coordinates of that point is the solution.

Given the system as:

y = 2/3x + 1

y = -2/3x - 1

Add both together to eliminate x

2y = 0

y = 0

Substitute y = 0 into y = 2/3x + 1 to find x

0 = 2/3x + 1

-1 = 2/3x

-3 = 2x

-3/2 = x

x = -3/2

The solution is: (-3/2, 0) = (-1.5, 0).

Therefore, the graph that shows the solution will intersect at (-1.5, 0), which is shown in the image attached below.

The cooper's weight as an adult dog will be 90 pounds.

Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.

A typical method for calculating a percentage is the formula shown below:

Calculation for the weight of Cooper as an adult;

Cooper's present weight is 20 pounds.

He will weigh about 350% as much as his current weight.

Calculate 350% of 20 pounds.

= (350×20)/100

= 70

The increment of the weight of Cooper will be 70 pounds.

Thus, the total weight is 20 + 70 = 90.

Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.

Answer:

ABF = 70

Step-by-step explanation:

Since angle EFD is 35, that means that angle AFB is also 35

Single BCD is 75, that means that angle BAF is also 75

Angles in a triangle add up to 180, thus:

75 + 35 + x = 180

x = 70

Answer:

a) 25% are bad

b) 75% are good

Step-by-step explanation:

We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).

300 - 75 = 225 good oranges.

So to find the percentage we have to take the selected amount divided by the total amount.

Bad Apples:                               Good Apples:

75 / 300 = 0.25                          225/300 = 0.75

However, that's a decimal or a number out of 1, we need a percent or a number out of 100. So we have to multiply both numbers by 100.

Bad Apples = 25%

Good Apples = 75%

Hence,

(580+x)-(720-x)=120

580+x-720+x=120

2x-140=120

2x=260

2*x=2*130

Jack is at (2/3) of the length of the beach (measuring from the point where they started).

Let's think that the whole beach is like a line track of length L.

We know that when Jill completes reaches the end (one complete run) Jack only completed half of it.

So in the time that jill covers the distance L, Jack covers a distance of L/2. So the ratio of their speeds is 2:1 (Jill's speed is double of Jack's speed).

At this point, Jill is on the end of the track and Jack is on the middle, so the distance between them is L/2.

Because of the ratios between the speeds, we know that when they meet again, Jill will have covered 2 thirds of that distance, and jack will cover the other third of that distance.

A third of that distance is:

(L/2)/3 = L/6

So, when they meet, Jack is at L/6 of the middle of the beach, which means that Jack is:

L/2 + L/6 = 3L/6 + L/6 = 4L/6 = 2L/3

Jack is at (2/3) of the length of the beach (measuring from the point where they started).

Answer:

x = 90

Step-by-step explanation:

In this figure the exterior angle is 130°

An exterior angle is the sum of the interior angles. The interior angles are x and 40 so x + 40 = 130 giving x = 130-40 = 90

Answer:

∠ x = 90°

(90 degrees)

Step-by-step explanation:

When two angles combine to make a straight line, we know that their angle values must add up to 180

Here, we can see that 130 combines with an inner angle to form a straight line. (I will be calling this interior angle z )

So, 130 + z = 180

   130 + z = 180

 - 130        -130

   z = 50

We also know that all angles in a triangle must add up to 180 degrees, and because we know the two other angles of our triangle now, we can find x

z + x + 40 = 180

50 + x + 40 = 180

90 + x = 180

- 90           -90

x = 90

So, the measure of angle x is 90°

The number of Apples that were in the given fruit salad is approximately; 2170 Apples.

We are given the ratio of apples to oranges as;

A:O = 31:11

Now, we are told that there are 2940 apples and oranges in total.

Thus, the fractions of apples and oranges of the total will be;

Apple fraction = 31/(31 + 11) = 31/42

Orange Fraction = 11/42

Thus;

Number of Apples = (31/42) * 2940
