Mr. Smith has 5 2/4 lb. of dry fish food. He will put an equal amount of food into 4 containers. How much fish food will be in each container.
(x + 5) * (x − 5) =
x² - 25
----------------
x * x = x² and 5 * (-5) = -25
Answer:
the answer is y = x-1
Step-by-step explanation:
y-y1 = m(x-x1)
y-9= 1×(x-10)
y=x-1
Answer: A
Step-by-step explanation:
<em>- and - = + </em>
-8 (4 - x) = 16
-32 + 8x = 16
8x = 16 + 32
8x = 48
x = 6
56 is your answer.
Equation for direct proportion is y = kx where k is the constant of proportionality. For your letters, it’s f = ka
We know 72 =k9, so k = 8
Then they want you to solve
f = 8•7
f = 56
