Let f(x)=3x^2-8 and let g(x)=4x+1. Find the given value f[g(-1)]
lana [24]

Answer:

19

Step-by-step explanation:

given:

f(x)=3x²-8

g(x)=4x+1

g(-1) = 4(-1)+1

g(-1) = -4 + 1

g(-1) = -3

hence

f[g(-1)]

= f(-3)

= 3(-3)²-8

= 3(9) - 8

= 19

A chef uses 4 3/4 cups of broth for 10 servings of soup. How much broth used in each serving of soup? Let x represent the number
kozerog [31]
Answer: 0.475 cups of broth per serving.

Explanation:


1) Ratio given:

 i) To facilitate the operations, transform the mixed number 4 3/4 cups into improper fraction:

4 + 3/4 = [16 + 3] / 4 = 19 / 4

ii) ratio broth: servings

\frac{ \frac{19}{4}cups }{10servings}

2) Proportion with the unknown number of cups of broth per serving:

\frac{ \frac{19}{4}cups }{10servings}= \frac{x}{1serving}

3) Solve for the unknown:

x = [19 / 4] cups × 1 serving / 10 servings = 19 / 40 cups = 0.475 cups

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel
gogolik [260]

Answer:

kevin is 6 years old

Step-by-step explanation:

Let Kevin's age now be a

Daniel's age now be b

Kevin is 3 years older than Daniel. -> a-3 = b

Two years ago, Kevin was 4 times as old as Daniel -> a-2 = 4(b-2) = 4b -8

-> a-3 -(a-2) = b - (4b-8)

-> - 1 = -3 b +8

-> -9 = -3b

-> b = 3

-> a = 6
