Answer:

Simplifying

6x + -2y = 30

Solving

6x + -2y = 30

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

6x + -2y + 2y = 30 + 2y

Combine like terms: -2y + 2y = 0

6x + 0 = 30 + 2y

6x = 30 + 2y

Divide each side by '6'.

x = 5 + 0.3333333333y

Simplifying

x = 5 + 0.3333333333y

A family is building a new house on a rectangular lot of land. the lot measures 7x by 11x and the house will be 2x by 3x. How mu

zubka84 [21]

71x^2
(71 x squared units of the house will be left).

Subtract Area of house from area of lot.
Area of house - 3x * 2x = 6x^2
Area of lot - 11x*7x= 77x^2
77xx -6xx = 71x^2

you cannot find the x value; not enough information is given.

Which is the BEST estimate of the average rate of change for the function given in the table, over the interval 2 ≤ x ≤ 4?

ladessa [460]

Answer:

Step-by-step explanation:

Use the slope formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Picking x = 2 and x = 4 as my two points (since the interval is 2 ≤ x ≤ 4), we get:

$m = \frac{15-3}{4-2} = \frac{12}{2} = 6$

So, the BEST estimate of the average rate of change for the function given in the table is 6.
