B. becuase 20 would stay the same. 12 would be the constant who be weeks because the question ask for how many weeks (x) till the length is 32
Answer:
x=-3
Step-by-step explanation:
4x-5y=8
Substitute the value -4 in for y
4x -5(-4) = 8
4x +20 = 8
Subtract 20 from each side
4x+20-20 = 8-20
4x = -12
Divide each side by 4
4x/4 = -12/4
x = -3
(-2, 0)
You can find this by getting the average of the x's and the average of the y's.
Answer:
B. All real numbers
Step-by-step explanation:
I assume the function is f(x) = 3^x, where x is an exponent.
Since an exponent can be a positive number, a negative number, and zero, x can be any real number. The domain of a function is the set of values that can be used for x.
Answer: B. All real numbers
