Answer:
x=3, y=3
Step-by-step explanation:
If we plug in 3 for each variable, their sum is 6, and the first equation will be true.
(f+g)(x)=f(x)+g(x)
(f+g)(x)=3x+4+8x+1
(f+g)(x)=11x+5
(f+g)(0)=11(0)+5
(f+g)(0)=0+5
(f+g)(0)=5
Answer: yes
Step-by-step explanation: slope is 4/3 and y intercept is 8
m= Y-20/0-9
4/3= y-20/-9
4/3 x -9 = y-20
-12 = y-20
Y=20-12
Y=8
The side with all the 9s and x is 12 just like its opposite side because this is a parallelogram. We can write the equation to add up the three segments; the ones on the left and right are 9-x:
9-x + x + 9-x = 12
18 - x = 12
x = 6
