The retail value of a car is V dollars today, and it decreases by 8% a year.
100% - 8% = 92%
That means 1 year later, the value of the car is 92% * V
92% = 92/100 = 0.92
The value of the car one year later is 0.92V.
Your answer is B. 0.92V
Notice that
so on the left side, a factor of <em>x</em> - 7 in the numerator and denominator can cancel
But we can only cancel them out as long as <em>x</em> ≠ 7 (because otherwise we'd have the indeterminate form 0/0 on the left side).
So, the equation is true for all <em>x</em> <u>except</u> <em>x</em> = 7. In set notation,
In interval notation,

Answer:
f(x) = (x - 2)²
Step-by-step explanation:
f(x) = x² - 4x + 4 is a perfect trinomial.
You know a trinomial is perfect when double the square root of the first term multiplied by the square root of the last term equals the middle term.
As an equation, a trinomial in the form ax² + bx + c = 0:
2√a√c = b is a perfect trinomial.
Perfect trinomial are factored in this form:
(√a ± √c )(√a ± √c ) = (√a ± √c )²
Whether the sign is + or - depends on if the middle term is positive or negative.
In f(x) = x²-4x+4, the middle term is a negative.
The square root of the first term is 1.
The square root of the second term is 2.
The factored form is (x - 2)²
You just have to add all the amounts of the ingredients.
4 2/5 + 3 1/2 + 12 3/4
You can first add all the whole numbers
4 + 3 + 12 = 19
Then, you can add all the fractions
2/5 + 1/2 + 3/4
To add all the fractions, you have to use the LCD. The LCD is 20. So, divide 20 with the denominator of each fraction and multiply the result with the numerator. The denominator of all fractions would now be 20.
So,
(2x4 + 1x10 + 3x5) / 20
(8 + 10 + 15)/20
33/20
The answer is an improper fraction. We divide 33 by 20 and get the remainder.
33/20 = 1 13/20
We have a whole number of 1, we add this to the sum of the whole numbers we got earlier.
19 + 1 =20
Finally, we put together the whole number and the remainder (fraction)
20 13/20.
Therefore, the recipe can make 20 1-cup servings. The remaining 13/20 can't make a full-sized cup.
