Answer:
8
5x + 7 + ----------
x - 5
Step-by-step explanation:
Divide 5x 2 - 18x -27 by x - 5 using synthetic division. Important: Please use the symbol " ^ " to denote exponentiation.
Divide 5x^2 - 18x -27 by x - 5 using synthetic division.
Setting up synth. div., we choose the divisor to be 5. That comes from (x-5)=0. Then,
5 / 5 -18 -27
25 35
------------------------
5 7 8
Because the remainder (8) is not zero, x-5 is not a factor of 5x^2 - 18x -27.
The "answer" is thus:
8
5x + 7 + ----------
x - 5
By adding one more person, they each save $8
Total saving = 5 x 8 = 40
So $40 is what the 6th person has to pay.
Therefore the total rent is 6 x 40 = $240.
Answer:
5x + 3y = -21
Step-by-step explanation:
i think sorry if its wrong
Y = kx
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
