Answer:

20  

Step-by-step explanation:

ƒ(x) = 3x² – 2

g(x) = 4x + 2

1. Add the functions

By definition,  

(ƒ + g)(x) = ƒ(x) + g(x)

3x²          - 2

<u>       + 4x + 2 </u>

3x² + 4x

(ƒ + g)(x) = 3x² + 4x

2. Evaluate (ƒ + g)(2)

(ƒ + g)(2) = 3(2)² + 4(2) = 3(4) + 8 = 12 + 8 = 20

Answer:

\displaystyle 20 = (f + g)(2)

Step-by-step explanation:

\displaystyle [4(2) + 2] + [3(2)^2 - 2] = [8 + 2] + [3(4) - 2] = 10 + [12 - 2] = 10 + 10 = 20

I am joyous to assist you anytime.

The rate of change of the relationship is 6/5

<h3>Rate of change of a line</h3>

The rate of change of a line is also known as the slope of the line. The formula for calculating the slope of a line is expressed as:

Slope =y2-y1/x2-x1

Given the coordinate points (-3,-2) and (2, 4). On substituting;

Slope = 4-(-2)/2-(-3)

Slope =4+2/2+3

Slope = 6/5

Hence the rate of change of the relationship is 6/5

Answer: y = -1/2

Step-by-step explanation:

Subtract both sides by 7/8

y = 3/8 - 7/8

Then combine like terms

y = -4/8

Then simplify

y = -1/2

Person A buys 12 granola bars and 7 cups of yogurt for $15.50. Person B buys 6 granola bars and 11 cups of yogurt for $11.50. Fi
ExtremeBDS [4]
<span>Granola bars cost $1 each and the yogurt is $.50 per cup. If we plug this in to each equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt equals $3.50, for a total of $15.50. The second statement would yield $6 + $5.50, which equals $11.50.</span>
