Hi there! :)

m(x) = 4x + 15
Find the value of "x" that would satisfy m(x) = 7:
4x + 15 = 7
Subtract 15 from both sides:
4x = -8
Divide both sides by 4:
x = -2.
Answer:
The third one
y+1=-2(x-3)
Step-by-step explanation:
Solve y+1=-2(x-3)
y+1=-2(x-3) becomes y=-2x+5
Then just graph it.
1:40 because 25 plus 15 equals 40 and if it went over 60 it would 2:00 so the answer is 1:40
C=students who will join
X=students who are in the club in total
20+c=x
