Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 5x + 7
g(x) = 3x - 1
<u>Step 2: Find</u>
- Substitute in functions: f(g(x)) = 5(3x - 1) + 7
- [Distributive Property] Distribute 5: f(g(x)) = 15x - 5 + 7
- [Addition] Combine like terms: f(g(x)) = 15x + 2

She has spent $4.80, $2.40 on each fruit, to be equal with mangos, since pineapples are cheaper then you have to multiply that as much times until you get equal with multiplying the mangos
Answer:
(-9/8, 1/36)
Step-by-step explanation:
Midpoint Formula: 
Step 1: Find midpoint <em>x</em>
x = (1/4 + -5/2)/2
x = (-9/4)/2
x = -9/8
Step 2: Find midpoint <em>y</em>
y = (-4/9 + 1/2)/2
y = (1/18)/2
y = 1/36
Step 3: Write midpoint coordinates
(-9/8, 1/36)
