Answer: 60%
Step-by-step explanation:
You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out
so you’ll end up with:
-2x-2y= -20
(+) x+2y=14
you’ll get : x = -6
then you plug in -6 for x, solve for y and your coordinates will be
(-6 , 10)
Answer:
A ≈ 2.83 units²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 3² × 
= 
≈ 2.83 units² ( to the nearest hundredth )
Answer:
y = 2x - 3.
Step-by-step explanation:
The perpendicular line will have slope - 1 / -1/2 = 2.
Using the point-slope form of the straight line:
y - y1 = m(x - x1)
Here m = 2 and (x1, y1) = (3, 3) so we have:
y -3 = 2(x - 3)
y = 2x - 6 + 3
y = 2x - 3.
The method you should chose is the quadratic formula
