Answer:
2x+18
Step-by-step explanation:
We can start by distributing the 2 to each term in the parentheses...
2(x)+2(9)
Multiply
2x+18
Answer:
c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)
53.45= 39.95 +0.15 (s +63) (use the distributive property)
53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)
53.45 = 49.40 +0.15s (subtract 49.40 from both sides)
4.05 = 0.15s (divide both sides by 0.15 so isolate s)
s= 27 (how many text messages were sent)

Answer:
(0,7)
Step-by-step explanation:
For a set of ordered pairs to be a function, there needs to be "ONE" value of y for each unique x value.
Thus, we see that the 3 ordered pairs given have x values of 0, 2, and 3.
Now, we look in the answer choices and find which ones are 0, 2, or 3 in x-coordinate.
That would be only (0,7). Now the original set has x = 0 corresponding to y = 1
Is that true for (0,7)?? NO!
x = 0 will now correspond to "TWO" values of y.
THis will make this NOT A FUNCTION.
So, (0,7) is correct.
