Number one or 2? so i can help you
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.
Best of Luck!
Answer:
-5 degrees per hour
Step-by-step explanation:
In 10 hours, the temperature dropped -50 degrees (38 + 12, and make it negative because the temperature went down, not up).
So divide -50 by 10
-50/10 = -5
Radius of ball is 6 inches. Then the volume is 904.32 
<u>Solution:</u>
Given that, radius of a ball is 6 inches.
We have to find the volume of the ball with 6 inches radius.
Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.
<em><u>The volume of sphere is given as:</u></em>

where r is the radius.
Here in our problem, r = 6


Hence the volume is 904.32
