Holy crp I'm sooo sorry. I started studying for my classes and didn't see this.

The y's increase +3 for every positive 1.

Answer:

38

Step-by-step explanation:

the rate of change is 3 and when x = 0 y = -1 so you multiply 3 times 13 witch equals 39 + (-1) = 38

24 is not a perfect square

Answer:

y=8x+36

Step-by-step explanation:

Use y=mx+b.  First find m, the slope.  

To do that, use y2-y1/x2-x1.  Use any two point combinations from the table.  You can use (6,84) and (12,132).  

Y2 would be 132 and Y1 would be 84, and X2 would be 12 while X1 is 6.  Just look at the pointss.  For example, Y2 is 132 because (12,132).  132 is in y's spot.  Same goes for x.

Now that we got y2, y1, x2, and x1, we can plug it into the formula and solve.

y2-y1/x2-x1= 132-84/12-6= 48/6= 8

This means the slope is 8.  Now, we need to find the y intercept.

Use y=mx+b again and use any pair of points.  I'm going to use (6,84).

y=mx+b.  Plug in the slope, which is 8.

y=8x+b

y=8x+b.  Plug in the y.  The y variable is 84 so plug that in.

84=8x+b.  Same for the x.  The x variable is 6 so plug that in as well.

84=8(6)+b.  Now simplify it.

84=48+b.  You want to isolate b to find the y intercept so move the 48 to the left side.  

It's now 84-48=b.  The 48 because negative because whenever you move a number to the other side, it switches its sign.

Solve.

84-48=b

36=b or b=36.  So the y intercept is 36.

We now have our slope and the y intercept.  

Slope: 8

Y intercept: 36

We can plug that into y=mx+b a final time.

y=8x+36

The equation of the linear model is y = 8x + 36

The standard form of a linear equation is given by:

y = mx + b

Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).

Let x represent the number of T-shirts and y represent the cost

Therefore we can use any two points to determine the linear equation to represent the model of the line in the form (x, y).

Using the points (6, 84) and  (24, 228). The equation is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-84=\frac{228-84}{24-6} (x-6)\\\\y-84=8x-48\\\\y=8x+36[/tex]

The equation of the linear model is y = 8x + 36

If 65% equals 147

Then to maintain 70% there is a need for 5% more

Which equals

Answer:

Step-by-step explanation:

147 maintained 65% attendance for the 1st 4 weeks

the goal is 70% on the next 4 weeks

ratio and proportion:

147 students =         x        

       65                     70      

65 (x) = 147 (70)

x = 10,290  

         65

x ≈ 159 students

therefore, the number of students would need to attend

                 daily for the next 4 weeks is

                 = 159 - 147

                 = 12 students

Step-by-step explanation:

25 x^2 - 81

Rewriting

(5x)^2 -9^2

This is the difference of squares

a^2 -b^2 = ( a-b)(a+b)

(5x)^2 -9^2 = ( 5x-9) (5x+9)

Answer:

4,8,14

Step-by-step explanation:

The three numbers are x = 4, y = 8 and z = 14 respectively.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the sum of three numbers as 26. The second number is twice the first and the third number is 6 more than the second.

Assume that the first number is x.

Then, the second number will be equal to 2x

The third number would be equal to (2x + 6)

Now, theirs sum is equal to 26. Therefore, we can write -

x + 2x + 2x + 6 = 26

5x + 6 = 26

5x = 26 - 6

5x = 20

x = 4

Then,

the second number (y) would be equal to (2 x 4) = 8

the third number (z) would be equal to (2 x 4 + 6) = 14

Therefore, the three numbers are x = 4, y = 8 and z = 14 respectively.

The discount is 30

169.99 is the price she will pay

Step-by-step explanation:

First find the discount

199.99 * 15%

199.99 * .15

29.9985

Rounds to 30.00

The discount is 30

199.99 - 30

169.99 is the price she will pay

Answer: About $30 less than the original price

Step-by-step explanation: 199.99x1.15 gives you 229.9885 and when you subtract 199.99 from that you get 29.9985 which is about 30 dollars.

Answer:

  d.  z = -48

Step-by-step explanation:

When j ║ k, corresponding angles are congruent, so ...

  x = 4z +3y

  57 = y + z

and the same-side interior angles are supplementary:

  57 +x = 180   ⇒   x = 123

__

This lets us write two equations in y and z:

  3y +4z = 123

  y +z = 57

Using the second equation to write an expression for y, we have ...

  y = 57 -z

Substituting this into the first equation gives ...

  3(57 -z) +4z = 123

  z +171 = 123

  z = -48 . . . . . . . subtract 171

The value of z that makes j║k is -48.

___

The corresponding value of y is 105.
