Which statement best describes the effect of replacing the function f(x) = 2x − 2 with the function g(x) = 2x + 5?
umka21 [38]
<h2>Answer:</h2>

The  statement which best describes the effect of replacing the function f(x) with g(x) is:

               The graph shifts 7 units up.

<h2>Step-by-step explanation:</h2>

The function f(x) is given by :

f(x)=2x-2

The function f(x) is a linear function with positive slope.

and the function g(x) is given by:

g(x)=2x+5

The function g(x) is a linear function with same positive slope.

Also, we know that any transformation of the type:

f(x) → f(x)+k

is a translation transformation such that it if k>0 then it is a shift k units upwards and if k<0 then it is a shift k units downward.

Here we have:

g(x)=2x+5-2+2

i.e.

g(x)=2x-2+7

i.e.

g(x)=f(x)+7

Hence, the function g(x) is a translation of the function f(x) 7 units upward.

Alla [95]

Answer:

He should serve 2 chocolate bars and 2 granola bars

Step-by-step explanation:

Let's define

x: amount of chocolate bar  

y: amount of granola bar

We are asked to solve the following optimization problem:

maximize 7*x + 2*y  

subject to

50*x + 25*y ≤ 150

5*x + 15*y ≥ 40

x ≥ 0

y ≥ 0

In the figure attached, the feasible region is shown. The solution is one of the vertex

vertex            objective function

(0, 2.667)       7*0 + 2*2.667 = 5.334

(2, 2)               7*2 + 2*2 = 18

(0, 6)               7*0 + 2*6  = 12

Nata [24]

Answer:

Ingrid collected 3 times as many Food boxes as she did cans of Food.

Step-by-step explanation:

Ingrid collected 6 cans of food from the food bank.

Ingrid collected 18 boxes of food from the food bank.

In order to determine the relationship

let cans of food = x = 6

So the boxes of food will be 3x = 3*6 = 18

So the relation between Cans of food and boxes of food will be

Ingrid collected 3 times as many boxes as she did cans
