Since b = 3 the equation changes
5a - 10(3) = 45
5a - 30 = 45
(Add 30 to both sides)
5a = 75
Divide 5 to both sides
a = 15
Answer:
9x-7y+28=0
Step-by-step explanation:
using formula
y-y1=m(x-x1)
y-4=9/7(x-0)
7y-28=9x
9x-7y+28=0
The correct answer is 1:2
Volume is : 4/3 x pi x radius (squared)
After Calculations : Volume is about 113.10 cubic cm
The solutions to this equation are (-8, 0) and (2, 0).
Hope this helps!
