Answer:
See attached image
Step-by-step explanation:
With this type of reflection, one has to convert the points of the form (x, y) into (y, x).
So the vertices of the triangle will transform the following way:
(4, 4) into image (4, 4)
(4, 1) into image (1, 4)
(2, 1) into image (1, 2)
Please see attached picture to find the new reflected triangle depicted in red.
Answer:
To meet her goal, Noelle must run more than
the rest of the month
Step-by-step explanation:
Let
h-------> the number of hours Noelle runs for the rest of the month
we know that
The inequality that represent the situation is
![10+5h>50](https://tex.z-dn.net/?f=10%2B5h%3E50)
Solve for h
Subtract 10 both sides
![5h> 50-10](https://tex.z-dn.net/?f=5h%3E%2050-10)
![5h> 40](https://tex.z-dn.net/?f=5h%3E%2040)
Divide by 5 both sides
![h> 8\ hours](https://tex.z-dn.net/?f=h%3E%208%5C%20hours)
![y\leq 2x-5](https://tex.z-dn.net/?f=y%5Cleq%202x-5)
↝ x-intercept
![2x-5=0\\2x=5\\x=\frac{5}{2}](https://tex.z-dn.net/?f=2x-5%3D0%5C%5C2x%3D5%5C%5Cx%3D%5Cfrac%7B5%7D%7B2%7D)
↝ y-intercept
y = -5
↝
means that the shade/area is below the graph as shown in the first picture.
![y\leq -\frac{1}{2}x-3](https://tex.z-dn.net/?f=y%5Cleq%20-%5Cfrac%7B1%7D%7B2%7Dx-3)
↝ x-intercept
![-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7Dx-3%3D0%5C%5C-x-6%3D0%5C%5C-x%3D6%5C%5Cx%3D-6)
↝ y-intercept
y = -3
↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.
First picture is first inequality
Second picture is second inequality.

OpenStudy (judygreeneyes):
Hi - If you are working on this kind of problem, you probably know the formula for the probability of a union of two events. Let's call working part time Event A, and let's call working 5 days a week Event B. Let's look at the information we are given. We are told that 14 people work part time, so that is P(A) = 14/100 - 0.14 . We are told that 80 employees work 5 days a week, so P(B) = 80/100 = .80 . We are given the union (there are 92 employees who work either one or the other), which is the union, P(A U B) = 92/100 = .92 .. The question is asking for the probability of someone working both part time and fll time, which is the intersection of events A and B, or P(A and B). If you recall the formula for the probability of the union, it is
P(A U B) = P(A) +P(B) - P(A and B).
The problem has given us each of these pieces except the intersection, so we can solve for it,
If you plug in P(A U B) = 0.92 and P(A) = 0.14, and P(B) = 0.80, you can solve for P(A and B), which will give you the answer.
I hope this helps you.

25x² + 1 = 5
25x² + 1 - 5 = 0
25x² - 4 = 0 By difference of two squares
(5x)² - (2)² = 0
(5x - 2)(5x + 2) = 0
5x - 2 = 0 or 5x + 2 = 0
5x = 0 + 2 5x = 0 - 2
5x = 2 5x = -2
x = 2/5 x = -2/5
x = 0.4 x = -0.4
x = + 0.4 or -0.4
