Answer:
10
Step-by-step explanation:
2x+46+3x-6 = 90
5x + 40 = 90
5x = 50
x =10
Answer: The correct option is (C). (2, -5).
Step-by-step explanation: The given function is
The vertex form of the function g(x) is
We know that if the vertex form of a function f(x) is written as
then its vertex is (h, k).
So, from equation (i), we can say that the vertex of function g(x) is
(2, -5).
Thus, (C) is the correct option.

Answer:
Step-by-step explanation:
Answer:
y = 4/3x + 1.
Step-by-step explanation:
The equation of the lines passing through (2,1) and (6,7) is:
y - 7 = (7-1)/(6- -2)(x - 6)
y - 7 = 6/8(x - 6)
y = 3/4(x - 6) + 7
y = 3/4x + 5/2.
So the line perpendicular to it has slope -1/3/4 = -4/3:
y - 9 = -4/3(x + 6)
y = -4/3 x - 8 + 9
y = 4/3x + 1.
