Answer:
3x + (5x -2)
Step-by-step explanation:
X is any number so 3 times a number is 3x. -2 plus 5 times a number is the same as 5 times a number minus 2. And the sum would be 3x + (5x - 2)
Find the length s of the circular arc. (Assume r = 2 and = 116°.)
Answer:
length of an arc = θ/360 × 2πr
θ=116°
r=2
π= 3.14
l= 116/360 ×2×3.14×2
l= 4.047= 4.05cm

PLEASE HELP!!! Question 1 & 2
Answer: I don't understand?
What question?
Step-by-step explanation:
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.
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.

In Exercises 15–20, find the remaining zeros of a polynomial
P(x) with real coefficients and with the specified degree
and zeros.
19. Degree 6; zeros: 0, 5, 1, 3i
Answer:
sending love to you that work is hard
Answer:
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.
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.
There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
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 = 5/14Kristen babysits 38 a week for $6.80 per hour. She earns an additional $224.00 in tips. How much did she make in 1 week?

Answer:
pretty sure it's 10 1/2
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
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].

Answer:
{-8, -7, 0, 6, 9}
Step-by-step explanation:
1. The range of a relation is the set of its possible output values, also known as the y-values of a function.
2. Let's find the y-coordinate of each point.
[tex]9, 6, 0, -7, -8[/tex]3. Now, let's order them (from least to greatest) to get the range.
[tex]-8, -7, 0, 6, 9[/tex] {-8, -7, 0, 6, 9}Therefore, the range of this relation is {-8, -7, 0, 6, 9}.
