Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.
Then we do: 83.82m / 3.23s = <span>25.9504644 m/s.
Then we convert that into miles per hour by </span>2.23694, so we do:
25.9504644 * 2.23694 = <span>58.0496318.
Then we round it to 58 mph.
So the answer is: The cheetah was running at 58 mph.

Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
We don't know the amount they get but the equation would be Claire 5 + a
I believe you mean to put "()" not "[]"
