Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
What is the question for the problem are you trying to figure out area or perhaps perimeter and of what the shaded or non shaded next time include that in your answer.
The domain of the function is (-∞, 1) U(1, ∞) while the domains are values greater than or equal to 1 that is y ≥1
<h3 /><h3>Domain and range of a function</h3>
The domain are independent variable for which the equation exist while the range are dependent variable for which the equation exist
Given the following functions
f(x) =2/x-1
g(x) = x+1
Determine (g ○ f)(x)
(g ○ f)(x) = g(f(x))
(g ○ f)(x) = g(2/x-1)
(g ○ f)(x) = (2/x-1) + 1
(g ○ f)(x) = 2+(x-1)/x-1
(g ○ f)(x) = x+1/x-1
Hence the domain of the function is (-∞, 1) U(1, ∞) while the domains are values greater than or equal to 1 that is y ≥1
