Answer:
X = 16
Step-by-step explanation:
These are supplementary angles, so they equal 180.
5x + 27 + 5x - 7 = 10x + 20
10x + 20 = 180
10x + 20 - 20 = 180 - 20
10x = 160
10x ÷ 10 = 160 ÷ 10
X = 16
Hope that helped you and have a good day!
6x²-5x-4=0
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3
Range is ouutput from inputing the input
domain is input
f(x)=4x
28=4x, x=7
30=4x, x=15/2
32=4x, x=8
34=4x, x=17/2
36=4x, x=9
domain is {7,15/2, 8, 17/2, 9}
