Answer:
Here is your answer
Step-by-step explanation:
3.(x+3)(x+5)
4.(x-8)(x+8)
5.(x+6)^2
Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies
Answer:
mmmmmmmm
Step-by-step explanation:
the answer ................
For an equation to be proportional, it must have no y intercept, and it must have a slope. So,
<span>y=4x+4 This equation isn't proportional because it has a y-intercept (+4)
y=4x+2 </span>This equation isn't proportional because it has a y-intercept (+2)
y=4x This equation is proportional because it has no y-intercept, and a slope.
