Answer:
Step-by-step explanation:
I haven't done this in a while, so I am very sorry if it is wrong, but I believe you take the angle measure of the part of the circle you need and put it over 360 then multiply by the formula for the area of a circle.
Answer:
k = 1
Step-by-step explanation:
Given that,
If (x+1) is a factor of (x), we need to find the value of k.
Using remainder theorem to find it.
Put (x+1) = 0
x = -1
Put x = -1 in equation below.
So, the value of k is 1.
Make each equation equal to each other, then solve for x.
-x+2=4x+7
-x-4x=7-2
-5x=5
X=-1
Sub x into one if the y formulas to find y
Y=4x+7
Y=4(-1)+7
Y=-4+7
Y=3
See my picture for how to graph the points.
Hope this helps!
I think I say B it's just a lucky guess
Hope you get an A!
