Answer:
x = -14
Step-by-step explanation:
Vertical angles are equal
so
9x + 184 = 7x + 156
2x = -28
x = -14
Input -3 for x
f(-3)=(-3)^2-4(-3)+3
f(-3)=9+12+3
F(-3)=24
A
Basically, this equation is called the "slope intercept form" and to change into into that, you must simplify the equation.
ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14
The answer is 30 i believe i rewrote it 3 times to check
