First, combine like terms on left side (5x). then move all variable terms to the left side and all constants stay to the right. (0x = 8) 0 times anything = 0, so there is no solution! :)

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

How do I work out 2x + 37 = 8x + 7
Setler [38]
You have to make sure that whatever you do to one side, you also do to the other.

2x + 37 = 8x + 7
2x + 37 - 2x = 8x + 7 - 2x
37 = 6x + 7
37 - 7 = 6x + 7 - 7
30 = 6x
30 / 6 = 6x / 6
5 = x
x = 5

Hope this helps! :)

Variables x and y are in direct proportion, and y = 12.5 when x = 25. If x = 40, then y =
BabaBlast [244]
25/12.5 = 40/y
cross multiply
(25)(y) = (12.5)(40)
25y = 500
y = 500/25
y = 20 <====
