Answer:
Elimination
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
Obasi earns 150% of his regular hourly wage while working overtime.
Let us convert percentage into fraction first:
To convert a percentage into fraction we need to use the following formula:
a%
Here, he earns 150% of his hourly wage while working overtime:
So,
150%=
Obasi earns
of his hourly earnings or 1.5 times of his hourly earnings while working overtime.
<u><em>Answer:</em></u>
1- The constant of variation is 
2- The constant of variation is 
<u><em>Explanation:</em></u>
When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa
<u>A direct variation relation is represented as follows:</u>
y = kx
where k is the constant of variation
Now, to get the constant of variation, all we have to do is substitute with the given x and y variables and solve for k
<u>For the given problems:</u>
<u>1-
</u>
<u>Therefore:</u>

<u>2-
</u>
<u>Therefore:</u>

Hope this helps :)
Answer:
-1(2+x)
Step-by-step explanation:
in the initial equation the -1 was distributed, this answer creates a product (multiplication). -1(2+x)= -2-x
