Answer:
Step-by-step explanation:
<em>Cost of game = $120</em>
<em>Current savings = $30</em>
<em>Rate for babysitting (per hour) = $5/hour</em>
<em></em>
<em>So, required equation is :-</em>
<em>120 = 5h + 30</em>
<em>5h = 90</em>
<em>h = 18</em>
<em></em>
<em>She must make $90 by babysitting for 18 more hours.</em>
Answer:
y = 2
x = 7
Explanation:
<u>Make the coefficient of "y" in equation 1 same</u>
{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1
→ 3x - 6y = 9 ........equation 2
<u>solving them using linear combination</u>

hope this helped!
Answer:
the domain is the set of all x coordinations and the range is the set of all y coordinates. therefore, the answer is C.
If you distribute the -4 you get -4x -28
