Answer:
(-1, 2)
this is the solution to the system of pair of linear equations
Step-by-step explanation:
The ordered pair that gives the coordinates of the point where the lines cross is the solution. The horizontal position of that point (-1) is the first number of the pair. The vertical position of that point (2) is the second number of the pair.
first get all variables on the same side, then use elimination to solve.
x = -3
y = -11
66π
SA= 2πrh+2πr²
SA= 2π x 3 x8 + 2π x 3x3
= 48π + 18π
=66π
hope this helps!
