What do you need help with? you have nothing here to answer
Answer: y = 980.333
Step-by-step explanation:
y-18=14
add 18 to each side
y = 32
Substitute 32 for y in 3(y+5)
3(32 + 5)
3(37)
111
So 3(y+5) = 111
Find the value of the variable y:
y-18=14 Add 18 on both sides:
y = 32
= 3y+15
_____________________
3y+15 = 2,956
3y+15 = 2956
3y = 2941
y = 980.333
D) {(-2,3),(-3,3),(-4,3)} Each member of the domain is assigned exactly one member of the range.
The domain must have only one value for y (range), unlike in the other 3 answer choices. If any section of a graph has two different y-values for the same x, then it is not a function.
