Then reflect across y = x
R is (3,0) which when reflected across y = x is (0,3)
S is (3,3) which when reflected across y = x is (3,3)

Answer:
u, AB6.4arctangent51°MN has the opposite direction of NMa ray has infinite length; a vector has finite lengthStep-by-step explanation:
1. The problem preamble gives you the two ways to name the vector. You can use either its name, or the two end points. (The starting point is named first, as it is with a ray.)
The vector shown can be referred to by the names ...
u or AB
__
2. The right triangle has legs 4 and 5, so the length is ...
length = √(4² +5²) = √41
length ≈ 6.4
__
3. Typically, you're given the leg lengths. The ratio of these is the tangent of the angle. The angle can be found using the inverse tangent function.
__
4. The tangent of the angle is the slope of the vector:
tan(A) = 5/4
A = arctan(5/4) ≈ 51°
__
5. The first letter named is the starting point of the vector. Vector MN starts at point M and ends at point N. Vector NM starts at N and ends at M. The directions of the two vectors are opposites.
__
6. A ray is like a vector of infinite length. The name of a ray includes a point on the ray. The name of a vector includes both end points. It is of finite length.
_____
Additional comment
A lot of math is invented to describe how things work in the real world. A vector is often used to represent velocity or force and other things that can be described by a magnitude and direction in the real world. A ray is more often used in problems in geometry, where that abstract concept serves a useful purpose.

Jacob is working two summer jobs, making $10 per hour washing cars and making $8 per hour landscaping. He must earn at least $170. This means that

If Jacob worked 4 hours landscaping, it means that
x + 4 ≤ 19 x ≤ 19 - 4 x ≤ 15
Also, 10x + 8 × 4 ≥ 170 10x + 32 ≥ 170
10x ≥ 170 - 32 10x ≥ 138
10x ≥ 138/10 x ≥ 13.8
The minimum number of hours is 14

Xavier had $100 in his lunch account. He spends $6 for lunch each day. Zack has $160 in his lunch account. He spends $10 each day. After how many days will the boys have the same amount of money in their accounts? How much money will they each have on that day?
Answer:
After 15 days they'll both have $10
Explanation:
100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)
[tex]100-6x=160-10x\\[/tex]
+10x on both sides
[tex]100+4x=160[/tex]
-100 on both sides
[tex]4x=60[/tex]
/4 on both sides
[tex]x=15[/tex]

Answer:
g(x) = (5x +26)/(x+5)
Step-by-step explanation:
To translate the function right h units and up k units, the transformation is ...
f(x -h) +k
You want h=-4 (4 units left) and k=-1 (1 unit down). So, the translated function is ...
[tex]f(x+4)-1=\dfrac{6(x+4)+7}{(x+4)+1}-1\\\\=\dfrac{6x+31}{x+5}-1=\dfrac{6x+31-(x+5)}{x+5}\\\\=\dfrac{5x+26}{x+5}[/tex]
The translated function is ...
g(x) = (5x +26)/(x+5)
__
The original function is in red with asymptotes shown in orange. The translated function is in purple with the asymptotes shown in blue. You can see that the function has been moved 4 left and 1 down.

32) In a triangle, the exterior angle is twice of each of the interior remote angles. The exterior angle is 1200. Find the measure of the three angles of the triangle.
Answer:
60 degrees each
Step-by-step explanation:
For the triangle, the sum of the interior angles is equal to the exterior
Let x and y be interior
Let z be the third angle
w be the exterior
w = x+y
120 = x+y
If the exterior angle is twice of each of the interior remote angles, then;
2x = 2y
x = y
120 = x+x
2x = 120
x = 60
Since x = y, y = 60 degres
From the triangle, the third angle will be 180 - 120
z = 180-120
z = 60
The measures of the 3 angles are 60 degrees each

(280 ÷ 7) - (7 ÷ 7)
C.
(280 + 7) ÷ (7 + 7)
D.
(280 ÷ 7) + (280 ÷ 7)
Answer:
(280+7) ÷ (7+7)
Step-by-step explanation:
hopefully this helps ya
The equation that is equal to 287 ÷ 7 is (280 + 7) ÷ (7 + 7). The correct option is C.
What is equation?An equation is a statement in mathematics that shows that two expressions are equal. It has two sides that are separated by an equal sign.
To find the value of 287 ÷ 7, we can use the following methods:
(280 ÷ 7) + (7 ÷ 7) = 40 + 1 = 41(280 ÷ 7) - (7 ÷ 7) = 40 - 1 = 39(280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5(280 ÷ 7) + (280 ÷ 7) = 40 + 40 = 80We can simplify 287 ÷ 7 as follows:
287 ÷ 7 = 280 ÷ 7 + 7 ÷ 7
Note that 7 ÷ 7 simplifies to 1, so we have:
287 ÷ 7 = 280 ÷ 7 + 1
Therefore, the answer is C. (280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5.

A painter is placing a ladder to reach the third story window, which is 14 feet above the ground and makes an angle with the ground at 70°
How far out from the base of the building does the ladder need to be positioned? Round your answer to the nearest tenth.
Answer:
4.8
Step-by-step explanation:
We are given the hypotunese or the slanted side which is the ladder length which is 14.
We are given an angle at the bottom which is 70 degrees.
We are asked to find the horizontal side which is adjacent to the angle at the bottom.
Since we have a hypotunese and a side adjacent to the angle, we are going to use the function cosine.
we use this formula
[tex] \cos(theta) = \frac{adj}{hypo} [/tex]
[tex] \cos(70) = \frac{x}{14} [/tex]

Which inequality is true if n = 81?
F 3n < 84
G n − 29 < 53
H 2n < 162
J n + 5 < 76
Answer:
G n - 29 < 53
Step-by-step explanation:
Replace n with 81 so it becomes
81 - 29 < 53
If you solve, 81 - 29 would be 52
Then you have
52 < 53
This is true since 53 is greater than 52

Parker drove a total distance of 4 and 1 over 2 miles during the months of June and July. If Parker only drove 1 over 8 of a mile every day, which expression shows the number of days he went driving? 4 and 1 over 2 ⋅
Answer:
36 days
Step-by-step explanation:
Total distance driven = 4 1/2 miles = 9/2 miles
Months of June and July ;
Miles driven per day = 1/8
Number of days Parker went driving :
Total miles driven / miles driven per day
9/2 miles ÷ 1/8 miles
9 /2 * 8 /1
(9 * 8) / (2 * 1)
72 / 2
= 36 days
Hence, Parker drove for 36 days
