P=w+l
42=(3x+7)+(2x-1)
42=5x+6
36=5x
x=36/5

plug in x

w=3(36/5)+7
w=28.6

l=2(36/5)-1
l=13.4

Write an equation for a line that is parallel to the graph of y = -3x + 6 and passes through the point at (-4, 7)
ale4655 [162]
Y = -3x + 6....the slope here is -3. A parallel line will have the same slope.

y = mx + b
slope(m) = -3
(-4,7)....x = -4 and y = 7
now we sub into the formula and find b, the y int
7 = -3(-4) + b
7 = 12 + b
7 - 12 = b
-5 = b
so ur parallel equation is : y = -3x - 5 <==

For the next units, you need to choose something big enough to hold a large number of these, so you would use square meters and acres. The answer is the third option: <span>number of people per square meter and number of animals per acre</span>
