Answer:
80+(15x)
Step-by-step explanation:
10 times 8=80
1.5 times 10=15
so she gets 80 dollars for the first 8 hours then for every extra hour she gets 15 dollars
<span>7x-6y=14
6x-y=-17
x = -4 y = -7 (SOLUTION) ; in ordered pair form (x,y) = (-4,-7)
</span><span>3x+8y=16
-9x-24y=-48
INFINITE SOLUTIONS: general form = (x,y) = ( x, -(3x/8)+2 )
Edited later:
</span>7x-6y=14
6x-y=-17
From second equation 6x - y = -17, we have y = 6x +17. Substitute this in the first equation to get
7x-6y=14
>> 7x-6(6x+17)=14
>> 7x-36x-102=14
>> 7x-36x=102+14
>> -29x=116
>> x=116/(-29)
>> x=-4
Now plug this value in y = 6x +17, to get
y = 6(-4) + 17 = -24 +17 = -7
So x = -4, y = -7 is the solution.
