Answer:
298000:100
x : 103
cross multiply: 100x=298000 x 103
x=306,940 or 307,000
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
If you have to add 2 to X to get it back to the original, it started out 2 to the left. (It would seem like it ought to be C, but when you add an subtract from the x value in functions, it's opposite of what you might think.)
Answer:
h(x) = (x + 5)² - 18
Step-by-step explanation:
Given
h(x) = 7 + 10x + x² = x² + 10x + 7
To obtain vertex form, use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
h(x) = x² + 2(5)x + 25 - 25 + 7
= (x + 5)² - 18 ← in vertex form
4 x 7 = 28
49 x 13 = 637
28/637
=4/91
