Answer:
(f+g)(x) = 7x -1 (Answer C)
Step-by-step explanation:
Rewrite these two functions, one above the other, for ease in adding:
f(x) = 5x - 2
+g(x) =2x + 1
------------------
(f+g)(x) = 7x -1
Answer:
Step-by-step explanation:
(a,9).......we dont know " a " (or x) but we do know y...it is 9
so sub in 9 for y and solve for x
y = 2x + 1
9 = 2x + 1
9 - 1 = 2x
8 = 2x
8/2 = x
4 = x <======= ur answer is D

Answer:
$1.95
Step-by-step explanation:
notebook = n
pencil = p
3n + 2p = 5.10
2n + 3p = 4.65
multiply top equation by 2 and bottom by 3
6n + 4p = 10.20
6n +9p = 13.95
subtract bottom equation from the top equation
-5p = -3.75
divide by 5, negatives cancel out
p = 0.75
sub p into either equation, I chose the original top equation
3n + 2(0.75) = 5.10
3n + 1.50 = 5.10
subtract 1.50 from both sides
3n = 3.60
divide both sides by 3
n = 1.20
p = 0.75
n + p = 1.95 (the fourth option)
