You should get photo math you can take a picture and it will give you the answer and show you how to solve it
neither
• Parallel lines have equal slopes
• The product of perpendicular slopes = - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y =
x + 3 is in this form
with slope m = 
rearrange 20x + 12y = 12 into this form
subtract 20x from both sides
12y = - 20x + 12 ( divide all terms by 12 )
y = -
+ 1 ← in slope-intercept form
with slope m = - 
Neither of the conditions for parallel/ perpendicular slopes are met
Hence the lines are neither parallel/ perpendicular
Answer:x=-2 y=-6
Step-by-step explanation:
11x+4y=-46..........(1)
7x-4y=10..............(11)
Add (1) and (11)
11x+7x+4y-4y=-46+10
18x=-36
Divide both sides by 18
18x/18=-36/18
x=-2
substitute x=-2 in (11)
7x-4y=10
7(-2)-4y=10
-14-4y=10
Collect like terms
4y=-14-10
4y=-24
Divide both sides by 4
4y/4=-24/4
y=-6
The mean from attending a review session will be the average of the numbers that are given.
<h3>What is a mean?</h3>
Your information is incomplete. Therefore, an overview will be given. Mean simply means average.
For example, if the given numbers are 2, 4, 6, and 10. The mean will be:
= (2 + 4 + 6 + 10)/4
=22/4
= 5.5

8x-10=3x+90. 8x-3x=90-10. 5x=80. x=16. So angle B is 3*16+90=138° :)
