ANSWER
The correct answer is option B
EXPLANATION
The equations are

and

When we multiply the second equation by
, we obtain;

When we combine this new equation with equation (1).

We can see that
has been eliminated from the equation.
We can then, solve for
and then substitute the result in to any of the equations to find
.
Hence the correct answer is option B
<u>Answer:</u>
B) Multiply the second equation by −3 to get −3x − 12y = −48
<u>Step-by-step explanation:</u>
We are given two equations:
--- (i)
--- (ii)
If we multiply the second equation by -3, we get:

--- (iii)
Combining equation (i) and (iii) to get:

3x and -3x cancel each other so x is eliminated and we are left with:

Therefore, the correct answer option is B) Multiply the second equation by −3 to get −3x − 12y = −48.

The Answers is
g(x) = (x + 1)/(x - 2)
h(x) = 4 - x
g(h(x)) = (4 - x + 1)/(4 - x - 2) = (5 - x)/(2 - x)
g(h(-3)) = (5 - (-3))/(2 - (-3)) = (5 + 3)/(2 + 3) = 8/5
g(h(-3)) = 8/5.
Answer:
1.7 ft
Step-by-step explanation:
We presume you want to find A. And we presume the people are standing shoulder-to-shoulder.
(327,495 mi)/(10^9 persons) = (3.27495×10^5 mi)/(10^9 persons) × (5280 ft/mi)
= 1.7291736×10^9 ft/(10^9 persons)
= 1.7292736 ft/person
≈ 1.7 ft/person
It would be: 12/75 = 4/25
So, your answer is 4/25

Answer:
A
Step-by-step explanation:
Plug in values
We know that x=4 and y= -8
just plug in numbers until one is correct
4-4(-8)=36
4+32=36
36=36
the answer is A
