Answer:
3
Step-by-step explanation:
All you have to do is take that bottom dot and count how many the rise is ----3 and how many the run is -----1.
Therefore, 3/1 is 3
F(x+1) = (x + 1)^3
= 3x + 3
= 3(0) + 3
= 3
I think is 3
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
