Answer:
<h2>∗ = 0.4x³</h2>
Step-by-step
We have :
2×(0,4)×15=12
(0,4)^2=0,16
(15y + ∗)^2 = 225y² + 12x³y + 0.16x⁶
= (15y)² + 2×(15y)×(0.4x³) + (0.4x³)²
then
∗ = 0.4x³
Fg(-2). Replace the x in f(x) with the equation of g(x):
fg(x) = 5(6x + 6) = 30x + 30
Therefore,
fg(-2) = 30(-2) + 30 = -60 + 30 = -30

Answer:
Step-by-step explanation:
The skope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, -1) and (5, -3). Substitute:
We have the equation:
Put the coordinates of the point (2 , -1) to the equation:
<em>add 4/3 to both sides</em>
Finally we have:
Answer:
42 = the number of hats Paula can knit from one yard of yarn
Step-by-step explanation:
The way this problem is written, the constant 42 is the multiplier of yards to get hats. That is, it has units of hats per yard, so represents the number of hats that can be knit from 1 yard of yarn.
_____
<em>Comment on the problem</em>
It seems more likely that the proportion should be written as ...
y = 42h
or
h = y/42
Then the constant would be the number of yards of yarn required for each hat.
