Answer:
(x-2)(x-12)
Step-by-step explanation:
x^2-14x+24=(x-2)(x-12)
Y=4
3y/4=12/3
y=4 3/3=1
12/3=4 so y=4
Answer: 
Step-by-step explanation:
I hope you mean y = x² - 12 and not y = 2x - 12.
You switch the y and x variables:
x = y² - 12
And solve for y:
x + 12 = y²

I would either use a histogram or a frequency chart, but histogram is easier and neater
Answer:
175
Step-by-step explanation:
(g*h)(x) is the product of two functions: g(x) = 25 and h(x) = 4 - x.
This product is equal to 100 - 25x.
Substituting -3 for x, we get
(g•h)(-3) = 100 - 25(-3) = 175
