well none of the answer choices match up with all these statements ...
C. it only matches up with the y-intercept given
D. it matches with the y-intercept, and the x- intercept is not quite on the 1
*but i would say C is the closest, because it has an x-intercept of -1 and the maximum point is at (1,4) ... which are the same with the given statements except that they have opposite signs, but yeah i have no clue*

Answer:
10.56%
Step-by-step explanation:
We are given A compact disc is designed to last an average of 4 years with a standard deviation of 0.8 years.
We are supposed to find What is the probability that a CD will last less than 3 years
We will use z-score formula:
Substitute the values in the formula
Now refer the z score table
So, the value of -1.25 is 0.1056 =
Thus , the probability that a CD will last less than 3 years is 10.56%
2.8 is the answer hopefuly
Answer:
x=4 or x= - 16
Step-by-step explanation:
|x+6|
Now subtract 7 which equals to 3.
|x+6|-7=3
|x+6|=10
Now remove the mode by adding plus minus sign in the front of 10.
x+6=±10
x+6=10 or x+6=-10
x=4 or x=-16
