Answer:

(f-g) (x) is

{4}^{x}  - 5x - 14

Step-by-step explanation:

f(x)=4ˣ - 8

g(x)=5x+6

(f-g) (x) is

{4}^{x}  - 8 \:  -  (5x + 6) \\   {4}^{x}  - 8 - 5x - 6

The final answer is

{4}^{x}  - 5x - 14

Hope this helps you.

A fruit stand has to decide what to charge for their produce. They need $5.30 for 1 apple and 1 orange. They also need $7.30 for
Aneli [31]

Answer:

A fruit stand has to decide what to charge for their produce.

They need $ 5.30 for 1 apple and 1 orange.

They also need $ 7.30 for 1 apple and 2 oranges.

TO DETERMINE

To put this information into a system of linear equations.

TO find a unique price for an apple and an orange

EVALUATION

Let the price of an apple = x and price of an orange = y

So From the first condition that they need $ 5.30 for 1 apple and 1 orange we get

\sf{x + y = 5.30}x+y=5.30 - - - - Equation 1

Again from second condition that they need $ 7.30 for 1 apple and 2 oranges we get

\sf{x + 2y = 7.30}x+2y=7.30 - - - - Equation 2

So the required Set of linear equations are

x + y = 5.30

x + 2y = 7.30

Equation (2) - Equation (1) we get

y = 2

From Equation (1) we get

x = 5.30 - 2 = 3.30

Hence price of an apple = $ 3.30

The price of an orange = $ 2

katovenus [111]

Good evening

Answer:

A) 6

Step-by-step explanation:

Firstly, the solution set to the inequality is : x > 7

Because, x + 8 > 15 ⇌ x > 15 - 8 ⇌ x > 7

Hence

The only number that is NOT in the solution set is 6
