Answer:

C) 18 square units

Step-by-step explanation:

There are many ways to go about solving this.  You could divide it into two triangles with a middle section.  But it might be easier just to count the squares:

whole squares = 12

half squares = 4 (which equals 2)

3/4 square = 4

1/4 squares = 4

(add the 3/4 and 1/4 squares to equal 4)

12+2+4=18

The line is written in slope-intercept form, which is y=mx+b.

mx represents the slope and b represents the y-intercept.

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.

Step-by-step explanation:

2a+1/3a + 5/4 -2a-3/6a^2

=4(2a+1)+15a/12a - 2a-3/6a^2

=a(8a+4+15a^2)-{2(2a-3)}/12a^2

=8a^2+4a+15a^2-4a+6/12a^2

Answer:

Multiply the second equation by −2 to get −4x − 12y = −48.

Step-by-step explanation:

Given:

4x + y = 4 (1)

2x + 6y = 24 (2)

Multiply the second equation by −2 to get −4x − 12y = −48.

4x + y = 4 (1)

−4x − 12y = −48 (3)

Variable x can be eliminated by adding the equations

4x + (-4x) + y + (-12y) = 4 + (-48)

4x - 4x + y - 12y = 4 - 48

0 - 11y = -44

-11y = -44

Divide both sides by -11

y = -44/-11

= 4

y = 4

Answer:

D

Step-by-step explanation:

x and y go up at a constant rate (or you can say it has a CROC or constant rate of chacge) y going up 5 for every one x

with our equation being y = 5x + 5

hope this helps <3

Answer:

Step-by-step explanation:

It would be D because to know if its linear, x has to increase by 1 and y by a constant rate.

X increases by 1 and y increases by 5

Answer:

4.

Step-by-step explanation:

The slope = (difference in y coordinates) / (corresponding difference in the x coordinates)

= (10-6)/ (2-1)

Julie is planning to make cupcakes for her school bake sale. There are 285 students, 17 teachers, and 324 parents attending the bake sale. If she decides to make a cupcake for each person, how many cupcakes does she need to make?

1 cup cake per person

Hence: total number of cupcakes

= 285 + 17 + 324

626 cup cakes

Answer:

w=6 in

l=3 in

Step-by-step explanation:

let w = width and length be 'w-3'

Two sides of w and two sides of (w-3) equal 18 sq in

18=2(w)+2(w-3)

18=2w+2w-6

4w=24

w=6

The width of rectangle is, 6 in.

And, Length of rectangle is 3 in.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The length of a rectangle is 3 inches less than its width

And, the area of the rectangle is 18 in.²

Now, We know that;

Area of rectangle = Length × Width

Let the width of rectangle = x

Hence, Length of rectangle = x - 3

Thus, We get;

Area of rectangle = Length × Width

18 = x (x - 3)

18 = x² - 3x

x² - 3x - 18 = 0

x² - (6 - 3)x - 18 = 0

x² - 6x + 3x -18 = 0

x(x - 6) + 3 (x - 6) = 0

(x - 6) (x + 3) = 0

x = 6 , x = - 3

But dimensions are not negative.

Hence, We get;

x = 6

Thus, the width of rectangle = 6 in.

Hence, Length of rectangle = x - 3

                                           = 6 - 3 = 3 in.

Answer:

10

Step-by-step explanation:

Answer:

  10 units

Explanation:

I will assume that we want to find the function that predicts the value of the car after x years, which likely is an exponential decay.

The function is: f(x) = $25,000*(0.85)^x

And the graph can be seen at the end of the answer.

We know that the value of the car decreases by 15% each year, then we can model this with an exponential decay.

The general exponential decay is given by:

f(x) = A*(1 - r)^x

Where:

A is the initial value, then we have A  = $25,000

x is the variable, in this case, would represent time in years.

r is the rate of decay, in this case, is the quotient between the percentage that decreases and 100%, so we will get: r = 15%/100% = 0.15

Then the exponential equation is:

f(x) = $25,000*(1 - 0.15)^x

     = $25,000*(0.85)^x

This is the function that models the value of the car after x years, the graph can be seen below.
