The equation for the line of best fit shows the relationship between the number of students enrolled

The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]

To do this, we make use of a graphing calculator that has the following calculation summary

A regression equation is represented as:

[tex]y = bx + a[/tex]

So, we have:

[tex]y = 90.2x - 177670.2[/tex]

Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]

Answer:

(125*2)/8=b

Step-by-step explanation:

The way to find the area of a triangle is to multiply height and width then divide by two and 125 is the area. Then that means 125=250/2.

Since the height is 8 we can make the equation (125*2)/8.

Answer:

8 (3 + 8x)

Step-by-step explanation:

Factor down the two values. The two multiples for 24 can be 8 and 3. The two multiple for 64 can 8 and 8. Overall, both the values are multiples of 8.

You put 8 out of the bracket since it's the GCF.  24 goes 3 times and 64 goes 8 times.

= 8 (3 + 8x)

Answer/Step-by-step explanation:

First you would plot -9 on the number line

Then you would go to the right 5 times which would take you to -4 and that would be you answer.

Answer:

(0, -2) and (3, 1)

Step-by-step explanation:

y = x - 2, y = (x - 1)² - 3

To solve this problem, we need to find when the x and ys in both equations are equal.

So,

y = x - 2 = y = (x - 1)² - 3

x - 2 = (x - 1)² - 3

Simplify right side.

x - 2 = x² - 2x - 2

Subtract both sides by (x² - 2x - 2)

x - 2 - (x² - 2x - 2) = 0

Simplify.

-x² + 3x = 0

Factor x.

x (-x + 3) = 0

Because the only way to get a product of 0 is to multiply a number by 0, either x = 0 or (-x + 3) = 0 (x would be 3 in this equation)

So, x = 0 or x = 3

Now, to find y, plug x = 0 x = 3 into one of the equations.

When x = 3, y = x - 2 = 3 - 2 = 1

When x = 0, y = x - 2 = 0 - 2 = -2

Just in case, let's check these values.

Put x = 0 and y = -2 into y = (x - 1)² - 3

-2 = (0 - 1)² - 3 = (-1)² - 3 = 1 - 3 = -2

So, x = 0 and y = -2 is correct.

Put x = 3 and y = 1 into y = (x - 1)² - 3

1 = (3 - 1)² - 3 = 2² - 3 = 4 - 3 = 1

So, x = 3, y = 1 is correct.

Thus, the answers are

(0, -2) and (3, 1)
