Answer:
v=-143
Step-by-step explanation:
45-v=188
-v=188-45
-v=143
v=-143
Answer:
Step-by-step explanation:
45 - v = 188
-v = 188 - 45
-v = 143
v = -143
There is one chance in 5 that the spinner will stop in a red section.
B.
It is 20 times more likely that the spinner will stop in a red section than any other section.
C.
If the spinner is spun 100 times it is certain that it will stop in the red section exactly 20 times.
D.
There is one chance in 20 that the spinner will stop in a red section.
Answer choices are on the picture below :)
f(x) = (x + 3)2 − 6
f(x) = (x + 6)2 + 3
f(x) = (x + 6)2 − 6
By completing the square, the second orderpolynomial in vertexform f(x) = (x + 3)² - 6 is equivalent to the polynomial in standardform f(x) = x² + 6 · x + 3. (Correct choice: B)
In this question we must change the form of the second orderpolynomial from standardform into vertexform. A common method consists in completing the square, that is, to transform part of the polynomial into a perfect squaretrinomial. Now we proceed to find the vertexform of the expression:
1) x² + 6 · x + 3 Given
2) x² + 6 · x + 9 - 6 Modulative property/Existence of additive inverse/Definition of addition
3) (x + 3)² - 6 Associative property/Perfect square trinomial/Result
By completing the square, the second orderpolynomial in vertexform f(x) = (x + 3)² - 6 is equivalent to the polynomial in standardform f(x) = x² + 6 · x + 3. (Correct choice: B)

Answer:
B. f(x) = (x + 3)2 − 6
Step-by-step explanation:
I just did this for "completing the square". Hope this helped!
If you would like to write an inequality to represent the situation, you can do this using the following steps:
x ... the amount of Alicia's paycheck
x/2 - $42.15 >= $20
x/2 >= $20 + $42.15
x/2 >= $62.15 /*2
x >= $62.15 * 2
x >= $124.3
The correct result would be x >= $124.3.
