Answer:
70
Step-by-step explanation:
Given:
m(x) = 10 + 3x
where,
m(x) = the amount of money he will have after a week of doing x additional hours of chores
x = additional hours of chores
Evaluate m(20), What does this mean?
m(20) = 10 + 3(20)
= 10 + 60
= 70
m(20) = 70
m(20) means additional hours of chores is 20
1/2*x - 7y = 7
1/2*x - 7 = 7y
1/14*x - 1 = y
y = 1/14*x - 1
The Second one y=1/3x
Because when you substitute x by 3 ( for example) then, you get y = 1
and that's right from the graph.
