Answer:

33

Step-by-step explanation:

Rewrite the bottom expression:

-2a-2b-2c-3x-3y

Factor the expression into two parts:

-2(a+b+c) + -3(x+y)

Substitute -3 for a+b+c and -9 for x+y:

-2(-3) + -3(-9)

6 + 27

33

Therefore, your final answer is 33

Based on housing data below which equation can be used to calculate fair housing prices?
VMariaS [17]

Answer:

B. y = 0.097x + 11.142

Step-by-step explanation:

In order to find the best equation to descibe the housing price, we have to calculate the slope of the line  first.

The equation of the line can be written as

y=mx+q

where m is the slope and q the y-intercept.

In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:

(1900, 196)

and

(2200, 225)

The slope of the line is calculated as:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{225-196}{2200-1900}=0.097

So, the slope of the line is 0.097.

Therefore, the correct option is the only one having a slope of 0.097, which is:

B. y = 0.097x + 11.142
