Answers
Answer:
B) 19
Step-by-step explanation:
The first step is to substitute 2 for x into the equation. f(2) = 2(3^2)+1
The second step is to square 3 which equals 9. f(2) = 2(9)+1
The third step is to multiply 2 by 9 which equals 18. f(2) = 18+1
The fourth step is to add 18+1 which equals 19. f(2) = 19

Answer:
x=1.4
Step-by-step explanation:
Put the x’s on one side and the rest on the other then solve for x
So...
4x + x = 2 + 5
5x = 7
5x/5 = 7/5
X= 1.4
Note: when switching sides the sign’s
(+ and -) get switched. A positive sign becomes negative and vice versa

James calculated the height of a cylinder that has a volume of 324 pi cubic inches and a radius of 12 inches. His work is shown below.

In step 1, he substituted into the volume formula incorrectly. In step 2, he calculated 12 squared incorrectly. It should be 144 rather than 24. In step 4, the Pi should have canceled, making the correct answer 13.5 cm. James calculated the height of the cylinder correctly.

Step-by-step explanation:
f(x) = 9 - 2|x + 2|
When x = 7, f(-7) = 9 - 2|(-7) + 2|
= 9 - 2|(-5)|
= 9 - 2(5)
= 9 - 10
= -1.

Answer:
-1
Step-by-step explanation:
Put -7 where x is and do the arithmetic.
f(-7) = 9 -2|-7+2|
= 9 -2|-5| = 9 -2·5 = 9 -10
f(-7) = -1
Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table at the right shows predicted percent returns for such sales. For example, if the store makes x dollars selling computer products, Enrique predicts the store will make 0.05x dollars from selling accessories. Part A In January and February of this year, the store made $2,500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year. If Enrique predicts sales from accessories and services for the entire year will be $5,000, about how much money must be made from computer product sales from March through December? Explain.
Answers
Answer:
Following are the solution to this question:
Step-by-step explanation:
x was its full computer product revenue from March to December. In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.
Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.
The sum of accessories to sell should be calculated, indeed, year-round.
It helps us to split into two parts
y = accessory sales in January and February + accessories sales in March and December
Use item 2
y = $2,500 + March to December accessories sale
Now use sections 1 and 3
y = $2,500 + 0.05x
The above equation rewriting gives
y = 0.05x + $2,500 (a)
This formula is compared with a standard y = mx+c interrupt slope
We got a pitch of 0.05 and a pitch of $2,500.

HELLP NOW I NEED ANSWER AND WORK/EXPLANATION!(Emily’s car broke down the weekend before she started a new job. She borrowed $880 from her parents, at an annual interest rate of 3%, to quickly pay for the car repairs. If Emily paid her parents a total of $893.20 in six months, how much simple interest did she pay?
Answers
Answer:
13.20 or 1.5%.
Step-by-step explanation:
Since Emily borrowed 880, you need to subtract 893.20 from 880. That equals 13.20. The percentage of interest is 1.5 because 6 months is half of a year and the annual interest rate is 3 percent.
