I got this wrong just to help you figure out the right answer. (I just did not answer and this is the final result)
1. Multiply the second line by 4: 4x+4y=16. They are the same line so there are infinitely many solutions.
2. Substitute for y.
x+(2x+10)=-2
3x+10=-2
3x=-12
x=-4
Plug x in
-4+y=-2
y=2
Final answer: (-4,2)
3. The answer is the first one because the solution is always where two lines intersect. The crossing of the x axis, y axis, and origin are irrelevant.
4. 2x+4=3x+1. This is because both equations define the value of y and therefore must be equivalent.
5. Infinitely many solutions. If you multiply the second equation by -3, you can tell it's coinciding or the same line.
Answer:
$15.40
Step-by-step explanation:
At a given hourly rate, the pay is proportional to the hours spent earning it. So, we have ...
pay/hours = $17.92/3.2 = (mowing pay) / 2.75
Multiply by 2.75 to get ...
(mowing pay) = $17.92·(2.75/3.2) = $15.40
Hilary earned $15.40 mowing lawns.
