Answer:
g(x) = 17-32x
Step-by-step explanation:
f(x) = 8x-3
g(x) = 5-2(8x-3)2
= 5-4(8x-3)
= 17-32x
Answer:
$6.50
Step-by-step explanation:
SET UP A SYSTEM OF EQUATIONS WHERE SANDWHICHES IS REPRESENTED BY S AND DRINKS BY D:
6S+4D = 53
4S+6D=47
ADD THEM TOGETHER
10S+10D=100
SOLVE FOR D
10D = 100 - 10S
D = 10-S
SUBSTITUTE THAT VALUE INTO ONE OF THE ORIGINAL EQUATIONS
4S + 6(10-S) = 47
4S + 60 - 6S = 47
COMBINE LIKE TERMS
-2S + 60 = 47
SUBTRACT 60 FROM BOTH SIDES
-2S = -13
DIVIDE BY -2
S = 13/2
S = $6.50

Answer:
Step-by-step explanation:
We'll go part by part.
"15 is equal to" so simple enough 15= now what is it equal to?
9 more than a number. Well what does that mean? it might help if we try out an actual number. What is 9 more than 3? 12, so another way of writing that is +9. It's not telling us the number we are adding 9 to so it's a variable. So we'll say x + 9.
This leaves us with 15 = x + 9, which you could even solve.
