Answer:
(5,4)
Step-by-step explanation:
multiply each equation by the value that makes the coefficients of x opposite
(-1) · (4x + 6y) = (-1) · 44
4x + 2y = 28
simplify
-4x - 6y = -44
4x + 2y = 28
add the two equations together to eliminate x from the system
-4x - 6y = -44
<u>+ 4x + 2y = 28</u>
-4y = -16
divide each term by -4
y = 4
substitute the value for y into one of the original equations, then solve for x
-4x - 6y = -44
-4x - 6(4) = -44
-4x - 24 = -44
+ 24 + 24
-4x = -20
divide by -4
x = 5
so, since x = 5 and y = 4 ....
the solution to the independent system of equations can be represented as a point.

hope this helps! :)
The inequality -y<3x-5 by multiplying by -1 becomes y>-3x+5.
1. Draw line y=-3x+5. When x=0, y=5, when y=0, -3x+5=0, x=5/3.
2. Choose the correct semiplane, substituting (0,0) into the inequality. Since 0 is not greater than 5, you can conclude that point (0,0) isn't a solution and doesn't belong to the shaded area.
3. The correct answer is first choice
An independent variable is a variable that can either be changed or controlled. We represent the independent variable as (X).
Let's look at an example.
<em>The number or hours Mike works at Sea World in June and the amount of money he will earn on his July paycheck.</em>
The independent variable because the amount of money he makes depends on how much money he earns.
