Find the equation of the line perpendicular to y = x -10 passing through point (10 , -5)
Answers
Answer:
y= -x+5
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the value of m first.
The product of the gradients of 2 perpendicular line is -1.
Given line: y= x -10
Gradient of given line= 1
m(1)= -1
m= -1
y= -x+c
To find c, substitute a coordinate.
when y= -5, x=10,
-5= -10 +c
c= 10-5 (+10 on both sides)
c=5 (simplify)
Thus, the equation is y= -x +5.

data from least to Greatest:
2.6, 3 , 4.9 , 5 , 5 , 6 , 6 , 7.9 , 8 , 8.2
Step-by-step explanation:
I got it from Khan Academy
The interquartile range (IQR) of the data set is 3.
The given data set is 5, 8.2, 6, 7.9, 5, 2.6, 3, 4.9, 6 and 8.
We need to find the interquartile range (IQR) of the data set.
How to find the interquartile range (IQR) of the data set?To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Now, the order of data from least to greatest is 2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2.
Q1=4.9 and Q3=7.9
So, IQR=Q3-Q1
=7.9-4.9=3
Therefore, the interquartile range (IQR) of the data set is 3.

Answers
Answer:
Step-by-step explanation:
Let the point P is at the origin (0, 0).
Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.
Rule for the dilation of a point by a scale factor = k
(x, y) → (kx, ky)
If k = [tex]\frac{1}{2}[/tex]
Then, A(8, 4) → A'(4, 2)
B(-2, 2) → B'(-1, 1)
C(4, -4) → C'(2, -2)
Now we can plot the new image with points A', B' and C'
Following are calculation to the given points:
Given:
[tex]\Delta ABC[/tex] under a dilation whose center is P
scale factor [tex]= \frac{1}{2}[/tex]
To find:
points=?
Solution:
In the given question we assume that the origin at the point [tex]P(0, 0)[/tex].
therefore the coordinates of [tex]A, B, \ and \ C[/tex] would then be [tex](8, 4), (-2, 2), \ and\ (4, -4)[/tex] respectively.
Scale factor dilatation rule[tex]= k[/tex]
[tex](x, y) \to (kx, ky)[/tex]

Answer:
Step-by-step explanation:
2x + 10 + x + 5 = 180 (Sum of co-interior angles}
Add the like terms
3x + 15 = 180 {Subtract 15 form both sides}
3x +15 - 15 = 180 - 15
3x = 165 {Divide both sides by 3}
3x/3 = 165/3

Using Simon's simulation, what is the probability of pulling a blue marble and the coin landing
39
50
Answers
Answer:
360/2500
Step-by-step explanation:
the blue marble is 15 times out of 50 = 15/50 reduces to 3/10
landing on tails is 24 out of 50 = 24/50 reduces to 12/25
to find the probability of both multiply together:
3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250
if you multiplied the numerator and denominator by 10 you get 360/2500.
the answer is 360/2500

Step-by-step explanation:
This questions asks us to find f(9).
It is asking us to find what f(x), or y is, when x is equal to 9.
f(x)=x-8
Therefore, we can substitute 9 in for every x.
f(9)=9-8
Subtract 8 from 9
f(9)=1
If f(x)=x-8, then f(9)=1
Answer:
f(9)=1

segment AB is dilated from the origin to create segment A prime B prime at A' (0, 8) and B' (8, 12). What scale factor was segment AB dilated by?
Answers
The scale factor which segment AB was dilated by is 4
How to determine the scale factor of dilation?The graph that completes the question is added as an attachment
From the attached graph, we have the following coordinates
A = (0, 2)
B = (2, 3)
The coordinates of the image of dilation are given as:
A' = (0, 8)
B' = (8, 12)
Divide the coordinates of A' by A
So, we have:
Scale factor = A'/A
This gives
Scale factor = (0, 8)/(0, 2)
Evaluate the quotient
Scale factor = 4
Hence, the scale factor which segment AB was dilated by is 4

We know the perimeter and the length
84= 2 ( l+7)
Divide each side by 2
84/2 = 2/2 (l+7)
42 = (l+7)
Subtract 7 from each side
42-7 = l+7-7
35 = l
The length is 35 inches
