f(x)=0
Domain are the set of x values
f(x)=0 , we find all the x values where y =0
At x intercepts y is always 0
so we find all the x intercepts.
x intercepts are the points where the graph crosses x axis
In the graph we can see that the graph crosses x axis at
-2.5 , -0.75 and 1
-2.5 , -0.75 and 1 are the domain where f(x)=0
Answer:
Step-by-step explanation:
We will need to solve the inequality:
–3x – 4 < 2
Before starting we need to understand 1 rule of inequalities. That is:
We change the inequality sign whenever we multiply or divide by a negative number. That means
< changes to >
and
≥ change to ≤
and vice versa...
Now, let's go ahead and solve the inequality:
"x" is the set of all values that is greater than "-2". So that's the answer.
x > -2
Answer:
you cant solve for x if it doesnt equal to something.
Step-by-step explanation:
Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.
