The square root of -15 is 3.87298335
0.5 / 100 * X = 3
X = 3 * 100 / 0.5 = 300 / 0.5 = 600
3/10 =50/x First multiply 50x10 then divide that number by 3 to get the answer
Answer:
r = 13
Step-by-step explanation:
The first step is to find b from y=mx=b using m=4/3 and (-4,8)

After solving the equation, b will equal -16/3 making the final equation be

Using the equation, you can solve for r.

This will bring the answer being r = 13
