The range for the given function is ~

Because, maximum value of y is 9 and minimum value is -6. so range lies between these two points (including them).
We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that x - y = 0.7 and x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us 2x = 1.7, and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use x + y = 1.
So now we have 0.85 + y = 1, so y = 1 - 0.85 = 0.15
The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).
Hope this helps!
Answer:
<h2>
x= 2/3</h2>
Step-by-step explanation:
x−6 = 4(2−3x)−8x
Rearrange terms
x-6= 4(-3x+2)-8x
Distribute
x-6= -12x+8-8x
Combine Like Terms
x-6= -20x+8
21x-6= 8
Isolate x
21x= 8+6
21x=14
x= 14/21
Simplify
x=2/3
