2x + y = 8
x - y = 10
--------------add
3x = 18
x = 6
x - y = 10
6 - y = 10
-y = 10 - 6
-y = 4
y = -4
solution is : (6,-4)
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
Answer:
Since the Line is Perpendicular
m.m'=-1
The line
y=x+8
Comparing with
Y=mx + C
m=1
m.m'=-1
m'=-1/m = -1/1 = -1.
y-y' = m'(x-x')
The point it passes is (-7,8)
y-8= -1(x--7)
y-8=-1(x+7)
y-8 = -x - 7
y + x -1 = 0.
or In Slope intercept Form
Just Make y the subject
y= -x + 1 ..... This is your answer.
Hope this helps!!!

What are the coefficients in the polynomial 4x²+3x-3?

<u>Coefficient:-</u> A number before a variable
<u>Coefficients in this polynomial:-</u>
4 (the number before x²) and 3 (the number before x)
<h3 />
So we conclude that the right option is:-
4, 3 (Option B)
<h3>Good luck.</h3>
