Sorry, But I had to put my answer as a screenshot because Brainly thought it was a link.
Answer:
x=5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
W + d = 770
w = d + 70
d + 70 + d = 770
2d + 70 = 770
2d = 770 - 70
2d = 700
d = 700/2
d = 350 <=== cost of dryer
Answer: -0.1111....
Step-by-step explanation:
If g(x) is -3^2x
Then to find g(-1), we need to substitute x with -1
So we get,
-3^2x
= -3^2x-1
= -3^-2
=-0.111111...
OR
1/-3^2
= 1/-9 (This is the answer in fraction form)
Answer:
B. Taking square root of both sides
Step-by-step explanation:
The first step given to us is
When we take square root of both sides we obtain;
Therefore the corect answer is B
