(1a) Do 4x and 15 + x have the same value when x is 5? How do you know?
2 answers:
Answer:
Yes, both have the same value ( 20) when x = 5.
Step-by-step explanation:
We have two functions:
y = 15 + x
y = 4*x
We want to see if these functions have the same value when x = 5.
Then we just need to replace x by 5 in both equations, and see if the values of y are the same
first function:
y = 15 + 5 = 20
second function:
y = 4*5 = 20
So yes, both functions are equal to 20 when x = 5.
Answer:
Yes.
Step-by-step explanation:
4(5)=20
15+5=20
