Answer: 2,3, and the last one.... I think
Step-by-step explanation:
I think your answer would be a line or a ray
I hope this helps!
Answer:
10(10)
Step-by-step explanation:
The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2
or can be written as 
<h3>Further explanation</h3>
This is a question about the composition of functions and how to get a domain function.
Given
and
.
We will form (b o a)(x) and then determine the domain.
<u>Step-1</u>

Replace each appearance of x in b(x) with
.

Thus, 
<u>Step-2</u>
To be defined, the value under the radical sign must not be negative. Therefore, the domain of
are processed as follows.

Both sides added by 3.

Both sides divided by 3.

Thus, the domain of
is
