we have

Equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side.


the factorization is equal to

therefore
<u>the answer is</u>

Answer: (-3, -21)
I'm not sure if that's what you wanted, sorry.
Answer:
this is an iscoceles triangle.
I know this because 2 of the sides are equal in length
Therefore,
AB=AC
3x-5=-2x+15
x-5=15
x=20
if x=20 then BC=2(20)
BC=40
Step-by-step explanation:
The phrase “the difference between a number and 5” as a variable expression would look like: x - 5
Answer:
std dev = 0.625
Step-by-step explanation:
Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.
We must change std deviation such that
P(X<12) =0.01
Mean would remain the same as 12.8 oz
From normal distribution score we can find
10th percentile is -1.28\
i.e. we must have

Std deviation should be 0.625
