Answer:
x = 7
Step-by-step explanation:
The point-slope equation of the line is ...
y -(-13) = -3(x -3)
Substituting -25 for y, we can solve for x:
-25 +13 = -3x +9
-21 = -3x . . . . add -9
7 = x . . . . . . . divide by -3
Answer:
a) y = 4x^2
Step-by-step explanation:
Because in a) y = 4x^2 the degree of equation is 2.
Angle: x
complement: 90-x
3x=90-x-14
4x=76
x = 19
90-x= 71
the answer is x1= -1 , x2= 5
