Answer: g(x) = f(x-2)

Step-by-step explanation:

When plugged into desmos, g(x) = 1/4(2^x) - 4

g(x) = f(x-2) is the only equation that lines up with this equation I stated above.

Note: if you try to do this yourself on desmos graphing calculator, make sure to add f(x) first (f(x) is: f(x) = 2^x - 4).

the maximum load of elevator is 480 pounds. Assuming that the average mass of student is 45 pounds, and m represents the number of students in the elevator, how many students can take the elevator at the same time

Answers

we can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

450 < 481

if you add another student, it would go over the limit.

hope this helps :D

Ella wants to make a fruit salad for herself and 5 friends.

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

1. How many cups of fruit salad does Ella have?

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person

1.) 15 cups
2.) 3 cups per person

Vertical rectangle:

A = bh

A = (5)(10)

A = 50

Horizontal rectangle:
