Answer:
Step-by-step explanation:
If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?
f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15
f(1) = 2 - 15 + 22 + 15
f(1)= 24.
No the result is not zero. So x - 1 is not a factor.
However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.
The numbers that do make this zero are -0.5, 3, 5
Which mean that the factors are (2x+1)(x-3)(x - 5)
To answer the question above, calculate the price per ounce of cereal of each local grocery stores
Save-Some-More $0.33 / ounce
Save-The-Most $0.28 / ounce
Spend-Less-Money $0.27 / ounce
Cheap-Food $0.3 / ounce
Thus, the final arrangement should be: (1) Spend - Less-Money, (2) Save-The-Most, (3) Cheap-Food, (4) Save-Some-More
5:45. If you add 3.45+2 it will give you 5.45 which you can convert the decimal into hour form
It can be done so in simple daily calculations such as calculating how much money you'll have after after you spend some.
<span>$100- $52= $48
and
if you switch it into an addition problem you will get
$100+(-52)= $48,
Or you can get $48 + $52 = $100</span>
Answer:
<em>The cost of a gallon of milk changed 31%</em>
Step-by-step explanation:
<u>Percent Change</u>
Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.
The formula is:
Where
v1 = original value
v2 = final value
The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:
Pc = 31%
The cost of a gallon of milk changed 31%
