Answer:
-3 and 5
Step-by-step explanation:
f(n) = n² - 2n - 15
numbers whose product is -15 and sums up to -2 = -5 and 3
= n²- 5n+3n - 15
= n(n - 5) +3 (n - 5)
f(n) = (n + 3)( n - 5)
n + 3 = 0 n - 5 = 0
n = -3 n = 5
Roots = -3 and 5
Answer: -1
Step-by-step explanation: Let the integer be x
It's additive inverse = -x
= x / -x = -1
Answer:
Step-by-step explanation:
8 pints per gallon
8x4=32 pints total
each container holds 1 pint so she needs 32 containers
Two angles that are supplements add up to 180°.
"The angle" is five times its supplement.
If I call the supplement 'S', then 'the angle' = 5S .
S + 5S = 180°
Combine like terms: 6S = 180°
Divide each side by 6 : S = 30°
The supplement of 'the angle' = 30°.
That's one of the choices.
"The angle" = 5S = 150°.
That's NOT one of the choices.
