<em><u>Question:</u></em>
4x + 2y = 0
- 4x – 9y= - 28
Solve each system by elimination
<em><u>Answer:</u></em>
The solution is x = -2 and y = 4
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 2y = 0 ------ eqn 1
-4x – 9y = - 28 ------- eqn 2
We have to solve the system of equations by elimination method
Add eqn 1 and eqn 2
4x + 2y -4x -9y = 0 - 28
0 + 2y - 9y = -28
-7y = -28
Divide both sides by -7
y = 4
<em><u>Substitute y = 4 in eqn 1</u></em>
4x + 2(4) = 0
4x + 8 = 0
4x = -8
Divide both sides by 4
x = -2
Thus the solution is x = -2 and y = 4
Answer:
Steeper
Step-by-step explanation:
As the slope of the line increases in value, the vertical distance becomes greater compared to the horizontal distance. Like in stairs or a roof, this results in the stairs and roof becoming steeper. The line becomes more vertical and steeper in its slant.

Fido's dog must lose 1.17 pounds each month to reach healthier weight.
Step-by-step explanation:
Given,
Weight of fido's dog = 35 pounds
Time period = 6 months
Goal weight to reach = 28 or less pounds
Let,
m be the weight to be lose each month.
Weight of dog - Time period * Weight to lose each month ≤ Goal weight
Dividing both sides by -6
Fido's dog must lose 1.17 pounds each month to reach healthier weight.
