Answer:
A
B
Q
D
Step-by-step explanation:
Well to factor a trinomial (Which is in the form ax^2 + bx + c) You would have to bring the A over to c so you can get x^2 alone. (If their isn't a gcf) You could also try to find what multiplys ac to add to b. but since that is not possible you would rewrite it x^2 -27x + 72 ( by multiplying the a to c) The you would rework it as normal (whatever two numbers multiply to 72 and add to -27. Which would be (x-3)(x-24). Then you would divide by the original A (x-3/18)(x-24/18). Then you would simplify that. (x-6)(x-4/3) and you would take any extra denominators and bring it to the front of the x. Making it (x-6)(3x-4)
My guess would be b. 5 1/3
Answer:
2. x = -7/2 and x = 1.
Step-by-step explanation:
2x^2 + 5x - 7 = 0
(2x + 7)(x - 1) = 0
x = -7/2, 1.
An inequality is with the >, <, or the =....... SO, initial one time reservation, you add onto the fee. 75 dollars each time, you pair that with c.
HOW IT SHOULD LOOK:
50(at the start) + 75c(the money charged for each cleaning) ≤ B
THE REASON WHY: the maximum budget is pretty much all you can spend, so the cost of the cleaning, as it says in the LAST LINE.... should not be over the budget, but can be under.... so we use the less than or equal to sign.
C is the number of leaning, 75 is the money charged for each cleaning, 50 is the initial cost of joining, and it should be added as part of the money you spent on the cleaning company....
and that's it
