Answer:
Step-by-step explanation:
Apparently, your system of equations is supposed to be ...
We can multiply the first equation by 2 and subtract the second equation:
2(4b -3h) -(5b -6h) = 2(64) -(44)
3b = 84
b = 28
Using the first equation, we can find the price of a hand towel:
4b -64 = 3h
h = (4/3)(b -16) . . . . . divide by 3 and factor out 4
h = (4/3)(28 -16) = 16
Bath towels cost $28 each, and hand towels cost $16 each.
If I did this correctly it simplifies to 0 = 8. So I think B is the correct answer. Hope this helps!!
2p - 10 - 4p - 7....combine like terms
-2p - 17 <===
We want to solve
x² + 8x + 7 = 0
Factorize the left side.
x² + 8x + 7 = (x + 1)(x + 7)
Therefore
(x + 1)(x + 7) = 0
When (x + 1) = 0, obtain x = -1.
When (x + 7) = 0, obtain x = -7.
The solutions are x = -1 and x = -7
Answer: x = -7 and x = -1.
Answer:
gradient=change in y/change in x
=y2-y1/x2-x1
=-8-(-16)/-10-(-8)
=8/-2
=-4
