Answer:

32

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 5x - 4

g(x) = -4x - 12

Step 2: Find f(g(x))

f(g(x)) = 3(-4x - 12)² - 5(-4x - 12) - 4

f(g(x)) = 3(16x² + 96x + 144) + 20x + 60 + 4

f(g(x)) = 48x² + 288x + 432 + 20x + 64

f(g(x)) = 48x² + 308x + 496

Step 3: Find f(g(-4))

f(g(-4)) = 48(-4)² + 308(-4) + 496

f(g(-4)) = 48(16) - 1232 + 496

f(g(-4)) = 768 - 736

f(g(-4)) = 32

How many teaspoons of brine shrimp every day? There are about 125,000 Brine shrimp in 1 pound. A pound contains 96 teaspoons. A
sveticcg [70]

Answer:

2\frac{38}{125}\ teaspoons

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

so

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons

Simplify

\frac{288}{125}\ teaspoons

Convert to mixed number

\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons

Pleasee help!! “It costs $2.75 to buy 3/4 lb of grapes. How much would it cost to purchase 9.5 lbs of grapes? Explain or show yo
avanturin [10]

Answer:

$34.83

Step-by-step explanation:

First convert 3/4 to decimal form: 3/4 = 0.75

Create a proportion using similar rates:

$2.75 / 0.75 lb  = x / 9.5 lb

where "x" represents the price of the 9.5 lbs of grapes we need to find.

Solve for x by multiplying both sides by 9.5 lb to isolate x completely

2.75 * 9.5 / 0.75 = x

Therefore x = $34.83
