Answer:
radius=3.19 km
Step-by-step explanation:
32/3.14159=r^2
r=3.19 km
In order to eliminate the y term, you need to find what y is equal to in the equation.
1. 6x-5y=-4
-5y=-4-6x
Y=6/5x+4/5
You then sub in 6/5x+4/5 in for y in the equation
2. 4x+2y=28
2y=-4x+28
Y=-2x+14
Hope this helps!
Answer:
2) x = 2
3) x = 40
Step-by-step explanation:
Complementary angles add up to 90° and supplementary angles add up to 180°

(2x - 9) + (3x - 11) = 180°
yes becasue it is 30

Answer: x = - 12
8x + 45 = 10x + 69
⇔ 10x - 8x = 45 - 69
⇔ 2x = -24
⇔ x = -12
