Answer:
I think the answer is D. 12 1/2
Step-by-step explanation:
If you add up the two thing it becomes: 15 cups of flour and 6 cups of milk. So if you divide 15 by 6, it's 2.5. Now all you have to do is 5 (since there are 5 cups of milk) times 2.5, and you get 12.5. And 12.5 is 12 1/2 in fraction form. Hence, the answer is D. 12 1/2.

What is the equation written in vertex form of a parabola with a vertex of (9, -1) that passes through (7. 7)?
O
A. y = 2(x - 992 - 1
B. y = 2(x + 1)2 - 9
O C. y = 2(x - 7)2 + 7
D. y = 7(x - 9)2 - 1
Answers
Answer:
[tex]y = 2\, (x - 9)^{2} - 1[/tex].
Step-by-step explanation:
If the vertex of a parabola is [tex](h,\, k)[/tex], there would exist a constant [tex]a[/tex] ([tex]a \ne 0[/tex]) such that the following would be an equation for this parabola:
[tex]y = a\, (x - h)^{2} + k[/tex].
The equation above is in the vertex form.
In this question, the vertex of this parabola is [tex](9,\, -1)[/tex]. (Such that [tex]h = 9[/tex] and [tex]k = -1[/tex].) Therefore, the equation of this parabola in the vertex form would be:
[tex]\text{$y = a\, (x - 9)^{2} + (-1)$ for some $a \ne 0$}[/tex].
It was also given that the point [tex](7,\, 7)[/tex] is on the parabola. In other words, if [tex]x = 7[/tex] and [tex]y = 7[/tex], the equation of this parabola ([tex]\text{$y = a\, (x - 9)^{2} + (-1)$}[/tex]) should be satisfied. In other words:
[tex]7= a\, (7 - 9)^{2} + (-1)[/tex].
Solve this equation for [tex]a[/tex].
[tex]a = 2[/tex].
Therefore, the equation of this parabola in vertex form would be[tex]y = 2\, (x - 9) + (-1)[/tex], which is equivalently [tex]y = 2\, (x - 9)^{2} - 1[/tex].

Step-by-step explanation:
Because P(X) has real coefficients, and 3i is a zero, we conclude that -3i is also a zero of P(X). Assuming that the multiplicities of the five aforementioned roots ( {0, 5, 1, 3i, -3i} ) are each 1, the 6th zero can be any real number.

In the school store, pencils cost 15 cents each and erasers cost 10 cents each. There is no tax. Gabby wants to spend exactly $2.00 on pencils and erasers.
How many of each can she buy? Provide detail explanation of your solution process and all possible strategies.
Answers
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.

Another marble is taken at random.
What is the probability of getting 2 reds?
Answers
Answer:
5/14Step-by-step explanation:
There are 5 red marbles out of 8.
The probability of the first red:
P(r1) = 5/8Now we have 7 total marbles and 4 of them are red.
The probability of the second red:
P(r2) = 4/7The probability of two red is:
P(rr) = 5/8*4/7 = 5/14
