Step-by-step explanation:
−4x+5−13x+39=180
Step 1: Simplify both sides of the equation.
−4x+5−13x+39=180
−4x+5+−13x+39=180
(−4x+−13x)+(5+39)=180(Combine Like Terms)
−17x+44=180
−17x+44=180
Step 2: Subtract 44 from both sides.
−17x+44−44=180−44
−17x=136
Step 3: Divide both sides by -17.−17x
−17
=
136
−17
x=−8
Answer:
x=−8
Hey there!
The equation for axis of symmetry is
The A, B, and C are:
Ax+By+C= f(x)
A=4 B=-8 C=12
So we have:
Two negatives make a positive.
8/8= 1
x=1 is the correct answer.
I hope this helps!
