The answer is D because a function means for every input you get exactly one output so
for every x you get one y
in D there is a coordinate (5,2) meaning that if you put in 5 for x you get 2 for y
but the new ordered pair also has 5 for x but has a difarent y value. this violates the definition of a funciton

8z + 3z = 8
Combine like terms: 8z + 3z = 11z
11z = 8
Solving
11z = 8
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Divide each side by '11'.
z = 0.7272727273
Simplifying
z = 0.7272727273</span>
3/5 of 40 = 24
1/4 of 40 = 10
24 + 10 = 34
Answer:
x=4
Step-by-step explanation:
2x + 14 = 22
Subtract 14 from each side
2x+14-14 = 22-14
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
