# Select the expression that is equivalent to (x^4/x^5)^3 a. x/x^2 b. x^7/x^8 c. x^12/x^15 d. x^12/x^5

B. x = 1.6 All you have to do is divide 6.4/4 and 4x/4. The 4s both ( 4x/4) cancel out and your left with x. Then you finsh off with 1.6 = x

The answer is D. i am pretty sure.

x = 2

Step-by-step explanation:

This blue line seems to be horizontal, and so a line perpendicular would have to be vertical. The only vertical line that passes through (2, 6) would be x = 2.

The axis of symmetry of y=ax²+bx+c is -b/(2a)

given

y=-4x²+6x-8
a=-4
b=6

axis of symmetry is -6/(2*-4)=-6/-8=6/8=3/4

What is the equation for the line of symmetry for the graph of the functiony=-4x^2+6x-8?

C.
x=3/4
