Question 1 of 40<br> If f(x) = 4x² - 6 and g(x) = x² - 4x-8, find (f- g)(x).
Aleksandr-060686 [28]

Answer:

\huge\boxed{\sf (f-g)(x) = 3x\² + 4x - 14}

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

The marching band is selling candy bars and fruit snacks for a fundraiser. Candy bars are sold for $2.50 and fruit snacks are $1
Flauer [41]

Answer:

220 candy bars

Step-by-step explanation:

Let the number of candy bars sold=c

Let the number of fruit snacks sold=f

A total of 650 items were sold.

  • Therefore: c+f=650

Candy bars are sold for $2.50

Fruit snacks are sold for $1.50

Total Income =$1,195

  • Therefore: 2.5c+1.5f=1195

We solve the resulting system of equation for c, the number of candy bars sold.

  • c+f=650
  • 2.5c+1.5f=1195

From the first equation, f=650-c

Substitute f=650-c into 2.5c+1.5f=1195

2.5c+1.5(650-c)=1195

2.5c+975-1.5c=1195

Collect like terms

2.5c-1.5c=1195-975

c=220

Therefore, 220 candy bars were sold.
