Answer:
Step-by-step explanation:
The equation of the line you will find should be in the form y =mx+c , where m is the gradient and c is the y intercept.
The gradient of a line that is perpendicular to a line [of a known gradient] is the negative reciprocal of the gradient of the first. i.e. if a is the known gradient and the perpendicular gradient is b, ab = -1. Therefore the -3b=-1 and b= 1/3
you can now write y = mx +c as y = 1/3x +c
As you have been given a coordinate, you can input these values into y= 1/3x + c
-12 = 1/3(6) +c
-12 - 2 = c
c = -14
hence the equation of the line is y= 1/3x -14
Ok, let's find how much does 1 yard of ribbon cost. Let's divide!
Each yard costs $1.50, so let's multiply that by 10
Marci will pay $15 for 10 yards of the ribbon.
ANSWER:
________
Line q = 3
Line v = -1/2
FORMULA
__________
y2 - y1 / x2 - x1
EXPLANATION:
_____________
First, we need to find the slope for line a only
We need to select two points from line q. The ones I selected are (-3,18) and (2,33)
y2 = 33
y1 = 18
x2 = 2
x1 = -3
33 - 18 = 15
2 - -3 = 5
15/5 = 3
Next, we need to find the slope for line v.
The two points I picked are (0,8) and (10,3)
y2 = 8
y1 = 3
x2 = 0
x1 = 10
8 - 3 = 5
0 - 10 = -10
5/-10 = -1/2
And that’s how you get your answer :)
PUN OF THE DAY
_______________
Why did Adele cross the road? To say hello from the other side.
I hoped this helped! And have a •AMAZING• day :3
Your answer would be A because the radius of the circle is half of its diameter.
Hope this helps <3 :)
10 is the missing number.
