Answer: $4.69
Step-by-step explanation:
Make equivalent fractions for each fruit.
Apples: 1.62/1 = x/2.5
X = $4.05 for 2.5 pounds of apples
Bananas: 0.48/1 = x/1.3333333333
X = .64 for 1.3333333333 pounds of bananas
Now add the results together to find the total cost.
4.05 + .64 = $4.69
15 cards = 9$
1 card = (9/15)$
12 cards = 9/15 * 12
= 108/15
= 7.2$
Answer:

Step-by-step explanation:
<h3><u>Given functions:</u></h3>
- f(x) = 4x² - 6
- g(x) = x² - 4x - 8
<h3><u>Solution:</u></h3>
Subtract both functions
(f-g)(x) = 4x² - 6 - (x² - 4x - 8)
(f-g)(x) = 4x² - 6 - x² + 4x - 8
Combine like terms
(f-g)(x) = 4x² - x² + 4x - 6 - 8
(f-g)(x) = 3x² + 4x - 14

Hmm they're both even numbers so maybe we can start by cutting each number in half.

18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.
