Answer:
70°
Step-by-step explanation:
90 + 20 + x = 180
110 + x = 180
x = 180 - 110
x = 70°
Neither. When graphing both lines they intersect but are not perpendicular.
Answer:
-8x^2 -4x
Step-by-step explanation:
f(x) = –4x – 2
g(x) = 2x
(f · g)(x) = (-4x-2) * (2x)
distribute
= -2x*4x -2x*2
= -8x^2 -4x
Answer:
The answer is No solution
Step-by-step explanation:
since you said equation I'm assuming it's in terms of x and y Just as a general equation
since the centre of the circle isn't at 0, you have to take that into account using the formula above. solve for the radius of the circle by substituting (4,0) into the formula and get your r value to replace in the original formula
