Answer:
part A 112/350 = x/100
part b : 32%
Step-by-step explanation:
Hello there! How are you today?
5a^2 + 2b^3, solve when a = 4 and b = -4
To solve for this, we must replace "a" with 4, and "b" with -4.
I will set it up;
5(4^2) + 2(-4^3)
Simplify the parenthesis (PEMDAS).
5(16) + 2(-64)
Remove the parenthesis by multiplying them by the numbers to the outside of them.
5 x 16 = 80
2 x -64 = -128
We are now left with:
80 - 128
Simplify.
-48 is your final answer.
I hope this helps!
Answer: A. 30
Step-by-step explanation:
We will plug the value of x, 15, into the given expression. Then, we will use the order of operations, also known as PEMDAS. View attached if you need a review.
5² + (x / 3)
5² + (15 / 3)
25 + (5)
30

Answer:
Step-by-step explanation:
The y-intercept exists where x = 0; plug in 0 for all the x's and solve the equation for y:
and
y = 3. The coordinate that represents this is (0, 3)
