This equation wouldn't work out without numbers, and the x's would cancel each other out.
Answer:
Step-by-step explanation:
y2-y1
x2-x1=
4-3
4-1 = 1/3
y=1/3x
Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±
/2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since
=
= 17. So b=13.
Answer:
12x^2+9x^2-25 (quadratic equation)
a=12, b=9, c=-25
put this in quadratic formula
