Answer:
-7
Step-by-step explanation:
-9x-3=60
add 3 to each side to cancel -3
-9x-3+3=60+3
simplify
-9x=63
divide by -9 to cancel the -9
-9x/-9=63/-9
simplify
x=-7
The answer to this question is c i think
U(x)=-2x²+3
v(x)=1/x →→ range of (uоv)(x, BUT range (uov)(x = u(v(x)), then :
u(v(x)) = -2(1/x²) + 3 →→u(v(x)) = -2/x² + 3
The range of -2/x² + 3 = {x∈R/x≠0}
