You are right the answer is B
Answer:
x=8
Step-by-step explanation:
Firstly the equation would be y=7.7x+59
(A)The slope is 7.7 (B) and shows that there is a 7.7 charge per week the person attends.
(A)The y intercept is 59 (B) and is the initial fee that the gym charges.
Answer:
The solution is x = -2, y = 4.
Step-by-step explanation:
2x + 4y = 12
x + y = 2
From the second equation: y = 2 - x.
Now substitute for y in the first equation:
2x + 4(2 - x) = 12
2x + 8 - 4x = 12
-2x = 4
x = -2.
Now find y by substituting x = -2 in the second equation:
- 2 + y = 2
y = 4.
