F(x) = 5 + 2x where x is the number of times he walks the neighbours dog
y-intercept is at y=5 and slope = 2
g(x) :- As x increases by 4 g(x) decreases by -8 so the slope is -8/4 = -2
when x = 0, g(x) = the y intercept is at -1 + (-8/2) = - 5
so equation of g(x) is g(x) = -5 -2x
h(x):- the slope is (3 - 5) / (1 - 0) [ difference in y values / diff in x values]
slope = -2
so we have h(x) = -2x + c where c = the y-intercept
when x = 0 h(x) = 5
so c = 5
h(x) = 5 - 2x
Now j(x)= 2x - 5 - slope is 2 and y intercept = -5
Actually if you multiply 5x1 then you get 5 then if you increase it by 4 you would only get 9. But thats just an example.
Answer:
A=80t+500 B=30t+700
820 Students
Step-by-step explanation:
80t+500=30t+700
-30t -30t
50t+500=700
-500 -500
50t=200
/50 /50
T=4
A=80(4)+500=820
B=30(4)+700=820
I’m pretty sure the answer is A1. 5j + 10x
56 gallons
I think..
Hope this will be helpful for you
