Answer:
y =
x + 7
Step-by-step explanation:
Given expression:
y = 4x + 3
Coordinate = (8,5)
Unknown:
The equation of a line perpendicular = ?
Solution:
A line perpendicular will have slope that is the negative inverse of the one given.
Equation of a straight line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y- intercept
For y = 4x + 3;
slope is 4;
A perpendicular line will have a slope of 
Let us find the y-intercept of the new line;
y = 5, x = 8
5 =
x 8 + c
5 = -2 + c
c = 7
the equation of the line perpendicular is;
y =
x + 7
Answer:
C. 2
Step-by-step explanation:
To solve slope, the formula is
. 9-3 is 6 and 5-2 is 3. So simplify 6/3 to 2.
Hope it's correct!
Answer:

Step-by-step explanation:
Hello There!
The first thing we want to do is find the proportional relationship between to two triangles
The smaller triangles longest side is 18
Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle
So the proportional relationship would be
36/18 or 2
Our next step is to find the the sides of the similar triangle
To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)
12x2=24
8x2=16
and we already know that the longest side measures 36
Now we can find the perimeter by adding all of the side lengths
36+24+16 = 76
So we can conclude that the perimeter of the dilated image is 76
Answer:
£40
Step-by-step explanation:
3+5=8
160÷8= 20
20× 5=100
20×3=60
100-60=40
Not 100% sure, but i think the answer is A. 1,365, Sorry if i get you wrong.
