Y = x^2 + 10x - 171
y = (x - 9)(x + 19)
x - 9= 0 x + 19 = 0
x = 9 x = -19
Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
Step-by-step explanation:
Cost of 5 books = $ 36.25
Cost of 1 book = $36.25 / 5 = $ 7.25
The unit price is $ 7.25
Hope it will help :)
No, it is not. Because it doesn't satisfy the first equation.
I would think 1 because songs can range any where from 1 minute to 3. <span />
Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°
z = x = 115°
