Answer:
R-{-5}
Step-by-step explanation:
you get the vertex by making the denominator =0
ex.z+5=0 ,z=-5
then we see if the rational function has a constant beside it ex. 3÷z+5-3 ,but in this you Don't have one so its 0
so the vertex would be (-5,0)
the domain =R-{-5} , range=R-{0}
Answer:
0.7
Step-by-step explanation:
67/10 is the same as 6.7 when you subtract the 0.7 you will remain with 6
Answer:
x = 7
Step-by-step explanation:
8x = 56
To solve this, we must simplify. To do this, we must divide each side by 8. This, in term, will give us the value of x.
8x = 56
---- ----
8 8
56/8 = 7
x = 7
Our answer is x = 7
