Answer: 576 cm³
Explanation:
Radius = Diamater ÷ 2 = 8 ÷ 2 = 4 cm
V = π r² h = 3 (4)² (12) = 576 cm³
18 eggs there are 12 in a single dozen
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps

Answer: Not correct
Step-by-step explanation:
If you plug 3 in for x and 7 in for y and solve you figure out there not equal. -1=-2(3)+7
-2(3)+7=1 because -2x3 is -6 and -6+7 is 1 which means -1=1 which isn’t true
Answer: The number is 0.75 or 3/4
Step-by-step explanation:
let x = the number.
Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x. x-(-4x)
Then, that equals 3 more than the number (x) = x+3
So the equation is x-(-4x)=x+3.
Then, solve the equation!
x-(-4x)=x+3
x+4x=x+3 (Distribute the negative to the parentheses)
5x=x+3 (Combine like terms)
4x=3 (Get the Xs on one side by subtracting x from both sides)
x=0.75 or 3/4 (divide by the coefficiant, 4, on both sides)
