<u>Answer:</u>
45
<u>Step-by-step explanation:</u>
We are given an equation <em>x - y = 30 </em>which we are to solve for x when the value of y is 15.
To solve this linear equation for x, we just need to substitute the given value of y into the equation to get the value of x.
x - y = 30
x - 15 = 30
x = 30 + 15
x = 45
Therefore, the value of x is 45 when y = 30.
Unfortunately this value is not in the given options but 45 is the correct answer.
Answer:
(2.5,5)
Step-by-step explanation:
The given function are 
and 
From the graph the two functions intersects at one point.
The point where they met is where the exponential function begins to exceed the quadratic function.
We can estimate this point from the graph as (2.25,4.76).
The closest to this point is (2.5,5)
Answer:
What our the points?
Step-by-step explanation:
If you know the points then you can find the domain of them. example (1,4)(2,9),(4,8)
The domain of these would be 1,2,4
Range is 4,9,8
