Answer:
D. 18
Step-by-step explanation:
- multiply both sides by 9/2, the reciprocal of 2/9.
4×(9/2)=x
- express 4×(9/2) as a single fraction.
4×9/2=x
- multiply 4 and 9 to get 36.
36/2=x
- divide 36 by 2 to get 18.
18=x
- swap sides so that all variable terms are on the left hand side.
x=18
Answer:
-1<x<1 and 1<x
Step-by-step explanation:
We are asked to determine the interval in which our function shown in the graph has positive values.
In order to do so, we have to see for what values of x on x axis, the graph is above x axis.
As we can see in the graph, when we move from x = -1 towards right, the graph is above x axis. And towards left of x=-1 , the graph is below x axis. Hence answer is
-1<x<1 and 1<x
I'm pretty sure the answer is c but idk
