Answer:
55:5 for the second one, 121:11 for the second one
Step-by-step explanation:
Answer:
40 • 18 = $720.00
18/2 = $9.00
9 • 6 = $54.00
720 + 54 = $774.00 total pay for the week
When we have a function such as h(x) = 2x, and we want to find the value of h at a given x value, we plug in the given number for x. For example, h(3) = 2*3 = 6.
We do the same thing with g(f(7)). In this case we plug 7 into f(x) for x, then plug the result of f(7) into g(x) for x.
f(7) = 15*7 - 12 = 93
g(93) = -15*93^2 + 14*93 - 10 = -128443
He set the factored expressions equal to each other. instead of setting them equal to zero
<h3>What are quadratic equations?</h3>
The name Quadratic comes from "quad" meaning square because the variable gets squared (like x2). It is also called an "Equation of Degree 2
The given solution of the quadratic equation in the question is
His work is shown below.
Here is where we use the zero product property
x+3 = 0 x+1 =0 We do not set them equal to each other
Hence He set the factored expressions equal to each other. instead of setting them equal to zero

4x - 9 = 15
Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)
4x = 24
Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)
x = 6
<u>The answer is B</u>
