Answer:
(B): (x - 2)/(x + 1)
Step-by-step explanation:
The numerator is x^2 + 5x - 14. That is equal to (x - 2)(x + 7).
The denominator is x^2 + 8x + 7. That is equal to (x + 1)(x + 7).
You can then eliminate (x+7) to get (x - 2)/(x + 1).
Answer:
negative numbers can't have a square root it would have to be imaginary
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the rent be x
<u>Discounted rent </u>
<u>Increase applied</u>
<u>Final rent:</u>
- (x - 50) + 10% = (x - 50)*1.1
<u>We know this is equal to x + 5% = 1.05x, comparing now</u>
- 1.1(x - 50) = 1.05x
- 1.1x - 1.05x = 55
- 0.05x = 55
- x = 55/0.05
- x = $1100

<em>From the above expression, the exponent of y is 1</em>
Answer:
A
Step-by-step explanation:
Substitute x = 5 into the expression
3(5 - 4) + 2(5) - 5²
= (3 × 1 ) + 10 - 25 = 3 + 10 - 25 = 13 - 25 = - 12 → A
