Answer:

1. [tex] m = slope = \frac{12}{7} [/tex]

2. [tex] y = \frac{12}{7}x [/tex]

3. Domain: 0≤x≤7

Range: 0≤y≤12

Step-by-step explanation:

1. Assuming 1 unit = 1 box on the grid, therefore, coordinates of C and D would be:

C(0, 0),

D(7, 12)

[tex] Slope = m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{7 - 0} = \frac{12}{7} [/tex]

2. Equation of the using the slope-intercept formula, [tex] y = mx + b [/tex], where,

[tex] m = slope = \frac{12}{7} [/tex]

b = y-intercept, which is where the line CD cuts the y-axis = 0

Plug in the values for m and b into the formula to get the equation of the line:

[tex] y = \frac{12}{7}x + 0 [/tex]

[tex] y = \frac{12}{7}x [/tex]

3. The domain for C to D part = all x-values = 0≤x≤7

The range = all y-values = 0≤y≤12

Answer:

This makes no sense as you dont say what type of triangle it is

Step-by-step explanation:

If its a equallateral its x = 89/7

Answer:

let the width of the playground be X

length will be (X+15)

area - length * width = 2700

(X+15)* X = 2700

x^2+15x-2700=0

x^2+60x-45x-2700=0

X(X+60)-45(X+60)=0

(X+60)(x-45)=0

x=45 because, the dimensions cannot be in negative

so length = 60 and width = 45

Given:

Annual interest rate = r⁡​%

Growth factor : x = 1 + r⁡​

The below function gives the amount in the account after 4 years when the growth factor is x⁡​ ⁣⁣.

[tex]A(x)=800x^4+350x^3+500x^2+600x[/tex]

To find:

The total amount in the account if the interest rate for the account is 3% each year and initial amount.

Solution:

Rate of interest = 3% = 0.03

Growth factor : x = 1 + ⁡0.03 = 1.03

We have,

[tex]A(x)=800x^4+350x^3+500x^2+600x[/tex]

Substitute x=1.03 in the given function, to find the total amount in the account if the interest rate for the account is 3% each year.

[tex]A(1.03)=800(1.03)^4+350(1.03)^3+500(1.03)^2+600(1.03)[/tex]

[tex]A(1.03)=800(1.12550881)+350(1.092727)+500(1.0609 )+618[/tex]

[tex]A(1.03)=900.407048+382.45445+530.45+618[/tex]

[tex]A(1.03)=2431.311498 [/tex]

[tex]A(1.03)\approx 2431.31 [/tex]

Therefore, the total amount in the account is 2431.31 if the interest rate for the account is 3% each year.

For initial amount the rate of interest is 0.

Growth factor : x = 1 + ⁡0 = 1

Substitute x=0 in the given function to find the initial amount.

[tex]A(1)=800(1)^4+350(1)^3+500(1)^2+600(1)[/tex]

[tex]A(1)=800+350+500+600[/tex]

[tex]A(1)=2250[/tex]

Therefore, 2250 was put into the account at the beginning.

Step-by-step explanation:

We need to find how many trips it will take to transport 58 cars

The explanation is simple:

58 / 6 = 9.6 repeating

So we round that quotient up to 10.

So the transport truck will need to take 10 trips to transport all 58 cars.

Answer:

D. Kelsey graphed the slope as the y-intercept and the y-intercept as the slope.

Step-by-step explanation:

The equation to graph was : y= 3x + 1 where the slope is 3 and the y-intercept is 1

However, Kelsey graph line passes through points (-3, 0)and (0, 3).From these points the equation of the line is;

m=Δy/Δx  where

m=the slope of the graph

Δy= 3-0 =3

Δx= 0--3 =3

m=3/3 = 1

The equation of the line should be;

m=Δy/Δx

1=y-3/x-0

1x= y-3

3+1x= y

y= 1x + 3 ----------where the slope is 1 and y-intercept is 3

So you can see here that in the original equation, the slope m is 3 and y-intercept is 1 as shown in the first attached graph.

While in the Kelsey's graph, the slope is 1 and the y-intercept is 3 as in the second attached graph.

Thus, the correct answer is D : Kelsey graphed the slope,3 as the y-intercept and the y-intercept,1, as the slope.

Answer choice A is incorrect because Kelsey didnot graph the y-intercept, 1 on the x-axis but graphed point (-3,0) on the x-axis.

Answer choice B is incorrect because on Kelsey's equation the y-intercept is 3 and not -3. i.e. y=1x + 3

Answer choice C is incorrect because Kelsey graphed the slope as up 1 right 1 which is okay per the equation , y=1x+3.However, this incorrect because the correct graph has a slope of 3.

Answer:

( -2,-3) is the midpoint

Step-by-step explanation:

To find the x coordinates of the midpoint, add the x coordinates of the endpoints and divide by 2

( -1+-3)/2 = -4/2 =-2

To find the y coordinates of the midpoint, add the y coordinates of the endpoints and divide by 2

( 3+-9)/2 = -6/2 =-3

( -2,-3) is the midpoint

It is not because a right triangle needs one right angle, and a right angle is 90 degrees

Step-by-step explanation:

Answer:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

Step-by-step explanation:

The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

Answer:

125 situps

Step-by-step explanation:

We can use a ratio to solve

25 situp          x situps

---------------  = --------------

12 pushup    60 pushups

Using cross products

25 * 60 = 12x

Divide each side by 12

25*60/12 = 12x/12

125 = x

Answer:

Option (2).

Step-by-step explanation:

Number of Democrats in a political discussion = 8

Number of Republicans = 3

Number of independents = 7

Total members in the discussion = (8 + 3 + 7)

                                                       = 18

Probability of selecting an independent = [tex]\frac{7}{18}[/tex]

Remaining members after selecting one independent = 17

Probability of selecting a Democrat = [tex]\frac{8}{17}[/tex]

Probability of selecting a Republican then a Democrat = [tex]\frac{7}{18}\times \frac{8}{17}[/tex]

                                                                                           = [tex]\frac{28}{153}[/tex]

Therefore, Option (2) will be the answer.

Answer:

g+14=64

Step-by-step explanation:

Answer:

64=14+g

Step-by-step explanation:

Sum of two numbers is 64, so that means you put 64 before the equals sign. All that remains is g and 14. It says the sum of 14 and g (gregs height) equals 64, so you know that in the equation they have to be added together.

Answer:

Hi There!

Your answer is:

Alyssa ran 2 and a half miles if she ran 2/3rds of the loop.

Step-by-step explanation:

1 loop= 3 & 3/4ths miles

WE NEED: 2/3rds of a loop

1 loop/ 3 = 3& 3/4ths miles /3

CHANGE MILES TO IMPROPER FRACTION!

1/3 loop = 15/4ths divided by 3

Multiply 15/4ths by the inverse of 3

15/4ths * 1/3 = 15/ 12

SIMPLIFY

1 & 3/12 or 1& 1/4

1/3loop = 1 & 1/4th mile

To get 2/3rds loop, multiply both sides by 2

2/3rds loop = 2 & 1/2 Miles
