If h(x)=x-7 and g(x)=x^ which expression is equivalent to (g•h)(5)?A) (5-7)^
B) (5)^-7
C) (5)^ (5-7)
D) (5-7)x^

Answers

Answer 1

Answer:

Answer:

A (5-7)^

Step-by-step explanation:

We have the next two functions h(x)=x-7 and g(x)=x^. We need to find (g•h) that is equal to g(h(x)) then:

(g•h)=g(h(x))=(x-7)^

Finally in the poin x=5 we have:

(g•h)=g(h(x))=(x-7)^

(g•h)=g(h(5))=(5-7)^

Then the answer is A

Answer 2

Answer: Assuming that by ^, you mean ², here's how you do this:
(g•h)(5) means that you need to solve g(h(5)). So, you plug 5 in for x in h(x), then you plug the solution of that in for x in g(x) like so:
$h(5)=5-7 \n g(h(5))= (5-7)^(2)$

The answer is A. (5-7)²

Hope this helps!

In number 1:

m = 10/3

b = 19

Step-by-step explanation:

To find the answers to these, simply look to the coefficient of x and the constant at the end of the equation. The number attached to x is always m (which is known as the slope). The number at the end is b (or the y-intercept).

When I started here, there were 500 employees. Since then, we have added 35% more employees, so we now have a total of __________ employees.

Answers

Number of employees when i initially started = 500
Percentage increase in the number of employees = 35%
Then
Increase in the number of employees = (35/100) * 500
   = 35 * 5
   = 175
So the total number of employees = 500 + 175
   = 675
So now we have a total of 675 employees. I hope the procedure is not that complicated for you to understand. You can generally use this method for solving similar type of problems in future without requiring any help from anyone.

The area of a rectangle is 21 m squared, and the length of the rectangle is 1 m less than twice the width. Find the dimensions of the rectangle. Help?

Answers

This should be right because I checked it afterwards
Width=W
Length=2W-1
The equation is as follows
W(2W-1)=21
$2W^(2)$ -W=21
Subtract 21 from each side
$2W^(2)$ -W-21
Group them/put them in parentheses..can't think of the right word right now
(2W-7)(W+3)
-7=I7I
You only do this for the first parenthese, 7÷2W=3.5
W=3.5
If W=3.5 then 2W-1⇒2×3.5-1⇒7-1⇒6
Length=6
If W=3.5 and L=6, then W(2W-1)=21
3.5(2×3.5-1)=21
Solve in parentheses first
3.5(7-1)=21
3.5(6)=21
3.5×6=21
The width is 3.5
The length is 6

Find the value of x
a. 7x=21
b.9x=-81
c. 88=-11x
d 0.5x=49

Answers

a. x=3 because you divide both by 7
b. x=9 because again you divide both by 9
c. x=8 because you divide both by 11 to isolate the variable
d. x=98 because you divide 49 by .5

a. 7x=21
x=3
b. 9x=-81
x=-9
c. 88=-11x
x=-8
x/2=49
x=98
