The correct answer would be -4
explanation:
2x-5<-12, add 5 to both sides so then you get 2x<-8, then divide by two, x<-4.
D
An easier way of doing it mentally is 3 x 25 which is 75 and then 1 x 25 which is 25
Answer:
It would be D. I got it correct on Edgenuity.
Step-by-step explanation:
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
ANSWER D
Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
