The answer is B.
Slope-intercept line is written as:
y=mx+b
m=slope
b=y-intercept
4 is the y-intercept because the line crosses the y-axis at 4.
The slope is -2 over 5, because slope is written as y over x.
So, if you start at the point at the 4, count 2 spaces down and 5 spaces right. The line crosses the point exactly, which is how you know the slope is accurate.
The answer would be 6. 21/3.5=6
1. 7m² + 6.5n - 4n + 2.5m² - n
7m² + 2.5m² + 6.5n - 4n - n
9.5m² + 2.5n - n
9.5m² + 1.5n = 1.7
Answer:
56-h-z runners
Step-by-step explanation:
The only number we're given is 56, so the only thing that we can do is create an expression
2 of the walls are 14 ft by 9 ft....
A = L * W
A = 14 * 9 = 126 sq ft.....and since there is 2 of them...2(126) = 252 sq ft
2 of the walls are 20 ft by 9 ft
A = L * W
A = 20 * 9
A = 180 sq ft....and since there are 2 of them ..2(180) = 360 sq ft
so for all 4 walls, we have : 252 + 360 = 612 sq ft
54 * 11 = 594 sq ft...so we need 11 double rolls...which costs 11(40) = $ 440
18 * 1 = 18 sq ft ....and we need 1 single roll...which costs $ 20
so we have 612 sq ft to cover....11 double rolls cover 594 sq ft and cost 440...and 1 single roll which covers 18 sq ft and cost 20
for a total cost of : $ 460 <==
