Do elimination
2x + y = 3
x - y = 3
Add these
3x = 6
X = 2
Plug in 2 for x
4(2) + 2y = 6
8 + 2y = 6
2y = -2
X = 2, y = -1
Answer:
-4
Step-by-step explanation:
y=3x - 1 x= -1
y = 3(-1) -1
y = -3 -1
y= -4
6×4=24
You keep change flip.
So you change ÷ to ×
And flip 1/4 to 4.
So it is 6×4=24
Answer:
C
Step-by-step explanation:
SchwarzschildRadius here:
So,
The equation for a circle is:

Where the center of the circle is (h,k), and the radius of the circle is r.
Substituting 7,8 for (h,k) and 11 for r in the equation gives us:

That would be standard form.
Hope this helps!
