Answer:

f(h(xc)) = 2xc-4

Step-by-step explanation:

Given

f(x) = x - 7

h(x) = 2x + 3

Required

f(h(xc))

First, calculate h(xc)

If h(x) = 2x + 3

Then

h(xc) = 2xc + 3

Solving further:

f(x) = x - 7

Substitute h(xc) for x

f(h(xc)) = h(xc) - 7

Substitute h(xc) = 2xc + 3

f(h(xc)) = 2xc + 3 - 7

f(h(xc)) = 2xc-4

A farmer planted 3 types of trees on 22 acres of land. He planted 48 trees per acre. What is the total of trees the farmer plant
antoniya [11.8K]
Hey there! :D

He planted 48 trees per acre. Ignore the '3 types of trees' part. I think the question is trying to confuse you. Multiply 48 by 22.

48*22= 1056

The farmer has planted 1056 trees.

I hope this helps!

Which inequality represents this sentence?
mezya [45]

Answer: it doesn’t make sense why you have random numbers underneath that inequality sentence. But if anything it would look like 6+2 < 9+3

Step-by-step explanation:

This < equals less than, or more than depending on what number it’s facing. Think of it as an alligator that eating the specific number (or larger number bc its hungry) so whatever the open side is facing is a more than but the number the closed side is facing is less than.

Alek and Ann start walking around a track at the same time and at the same place. It takes Ann 6 minutes to walk around the trac
Yuki888 [10]

Answer:

3 3/7 minutes

Step-by-step explanation:

This calculated using the formula:

1/x + 1/y = 1/n

Where

x = Number of minutes it took Ann to walk = 6 minutes

y = Number of minutes it took Alek to walk = 8 minutes

n = Number of minutes it would take An and Alek to reach the starting point at the same time

1/6 + 1/8 = 1/n

Lowest Common Denominator = 24

4 + 3/24 = 1/n

7/24 = 1/n

Cross Multiply

7n = 24

n = 24/7

n = 3 3/7 minutes

It would take them 3 3/7 minutes to reach the starting point at the same time.

Sumone help me plz lol
Gre4nikov [31]

Answer:

3x + 7

Step-by-step explanation:

I am not 100% sure if this is right but I did try and thats what counts. The reason I think this is because since we don't know what <em>x</em> is we cant add or subtract it so instead we subtract it from 6 and put 12 and 5 together. Hope this helps
