Answer:
y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative
you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped

Translate the sentence into an inequality five substracted from the product of 8 and a number is at most 25 use the variable x for unknown number
Answer:
8x - 5 ≤ 25
Step-by-step explanation:
Given that the unknown number is x
product of 8 and a number is expressed as 8x
five substracted from the product of 8 and a number is expressed as 8x - 5
Since this expression is at most 25, the inequality sign that you are to use will be ≤ (less than or equal to) since it cannot be greater than 25. Hence the required inequality expression is 8x - 5 ≤ 25
Paper clips are sold in boxes of 1000.
Each box costs £15.40
The table below shows the discount offered for large orders.
Ethan orders 5 boxes of paper clips.
Work out the amount of discount Ethan gets.
Answer:
6.5%
Step-by-step explanation:
1000 in a box and he orders 5 boxes.
1000x5= 5000
So he orders 5000 paper clips
1 box is £15.40 and he order 5, so £15.40x5= £77
£77 is between £55 and £79.99 so he will get 6.5% discount.
After the discount he will pay £71.99

A local hotel has 158 rooms. Due to a scouting event, the entire hotel booked except for two rooms. If the girls scouts are using three times as many rooms as the boy scouts, how many rooms are the boy scouts using?
Answer:
39
Step-by-step explanation:
Let, total rooms girls booked be x and total rooms girls booked be y.
entire hotel was booked except two rooms.
so, total = 158-2 = 156
x+ y = 156
this is equation 1.
also, girls are using three times more room than boys.
so, y=3x
substituting y=3x in 1st equation,
x+ 3x = 156
or, 4x = 156
or, x= 156/4
x= 39
1) Calculate the distance between point A: (22,12) and point B: (30,27)
Answer:
17
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(30 - 22)² + (27 - 12)²
√(8)² + (15)²
√ 64 + 225
√289

The circle has center O . Its radius is 6 cm , and the central angle a measures 40. What is the area of the shaded region? Give the exact answer in terms of , and be sure to include the correct unit in your answer.
The circle has center O. Its radius is 6 cm, and the central angle measures 40. What is the area of the shaded region? Give the exact answer in terms of π, and be sure to include the correct unit in your answer.
Answer:
= 4π
Step-by-step explanation:
Area of the shaded region
Sector area = (central angle)/360° x area of circle
= (central angle)/360° x πr²
= 40°/360° x π6²
= 1/9 x 36π
= 36π/9
= 4π
If a=3 and b=7, find the value of
2a + 3b
Answer:
27
Step-by-step explanation:
here's your solution
=> a = 3
=> b= 7
=> the given expression is ( 2a + 3b)
=> bu putting value of a and b in equation
=> we get , (3*2 + 7*3)
=> 27

What is the slope of the line that passes through the points (-2, 8)(−2,8) and (-22, 8) ?(−22,8)? Write your answer in simplest form.
Answer:
0Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(-2, 8) ⇒ x₁ = -2, y₁ = 8
(-22, 8) ⇒ x₂ = -22, y₂ = 8
So, the slope:
[tex]m=\dfrac{8-8}{-22-(-2)}=\dfrac{0}{-20}=0[/tex]
lara chooses a number less then 20 she divides it by 2 and then adds 6 she then divides whis result by 3 her answer is 4.5 what was the number she started with
Answer:
Lara started with the number 15.
Step-by-step explanation:
In order to solve this problem, you can write an equation representing the situation. You can do this by applying the described actions to a variable; I'll use n for this:
(n ÷ 2 + 6) ÷ 3 = 4.5
Now, you can just solve this equation for n:
(n ÷ 2 + 6) ÷ 3 = 4.5 (given)
n ÷ 2 + 6 = 13.5 (multiply both sides by 3)
n ÷ 2 = 7.5 (subtract 6 from both sides)
n = 15 (multiply both sides by 2)
So, now you know that Lara's starting number was 15.

5x - 10 = 4x + 20 {Subtract 4x from both sides}
5x - 4x - 10 = 20
x - 10 = 20 {Add 10 to both sides}
x = 20 +10
x = 30°

Answer:
The distance between the two points is 13 units
Step-by-step explanation:
on a graph, to find the distance you can either count each square/unit or you could add the points together not counting if they're negative or not
basically just add them in absolute value |-5| + 8= 13

The equation of an ellipse is x2/16 + y2/36= 1 , and the ellipse is centered at the origin. Find the vertices of the major axis and determine whether the ellipse has a horizontal or vertical major axis.
Answer:
steps below
Step-by-step explanation:
x²/16 + y²/36= 1
x²/4² + y²/6²= 1
Eclipse center ed origin: standard formula
²/radius of minor axis + y²/ radius of major axis =1
Vertices of major axis: (6 , 0) and (-6 , 0) ... horizontal
vertices of minor axis: (0 , 2) and (0 , -2) ... vertical
In a race , Ram covers 5 km in 20 min. How much distance will he cover in 100 min ? This is for (348919) ;-; I hope I was not mean if so am sorry but is for ( 348919)
Answer:
25 km
Step-by-step explanation:
Distance covered in 20 min = 5 km
Distance covered in 1 min = 5/20 km or 1/4 km.
Distance covered in 100 min =
1/4 km x 100 = 25 km
The ratio R S R T = 1 2 . Point R is at (2, 5) and point T is at (–4, –7). Which could be the coordinates of S? A. (–1, –1)
Answer:
The coordinates of the point S could be;
A. (-1, -1)
Step-by-step explanation:
The given parameters are;
The ratio of the length of the line RS to the length of the line RT = 1:2
The coordinates of point R = (2. 5)
The coordinates point T = (-4, -7)
Therefore, we have;
[tex]\dfrac{The \ length \ of \, RS}{The \ length \ of \, RT} = \dfrac{1}{2}[/tex]
[tex]\therefore {The \ length \ of \, RS} = \dfrac{1}{2} \times The \ length \ of \, RT[/tex]
The length of the line RT = √(((2 - (-4))² + (5 - (-7))²) = 6·√5
Therefore, we have;
[tex]{The \ length \ of \, RS} = \dfrac{1}{2} \times 6\cdot \sqrt{5} = 3 \cdot \sqrt{5}[/tex]
When the coordinates of the point S = (-1, -1), we have;
The length of the line RS = √(((2 - (-1))² + (5 - (-1))²) = √45 = 3·√5
Therefore, the coordinates of the point S could be (-1, -1)
