Answer:
fine out that what is 80%?
Step-by-step explanation:
the question is not complete
Let's start by solving the first equation.
a) -3 = 7 + 2t/3
To begin simplifying this equation, we should multiply both sides by 3 to get rid of the denominator on the right side of the equation.
-9 = 7 + 2t
Next, we should subtract 7 from both sides to cancel out the 7 on the right side.
-16 = 2t
Finally, we should divide both sides by 2.
t= -8
Now let's move on to the next equation.
b) 4(5x-2) = 7(2x+3)
Let's use the distributive property to get rid of the parentheses and their coefficients.
20x-8 = 14x + 21
Now, lets subtract 14x from both sides of the equation.
6x - 8 = 21
Next, let's add 8 to both sides of the equation.
6x = 29
And divide both sides by the coefficient of x, which is 6.
x = 29/6 or 4 5/6
Now for the last equation.
C) 2x - 6 = 20 - 2.5x
First, we should add 2.5x to both sides to cancel out the -2.5x on the right side of the equation.
4.5x - 6 = 20
Now, let's add 6 to both sides to get the variable term alone.
4.5x = 26
Finally, we should divide both sides by 4.5 to get x by itself.
x = 5 7/9
Hope this helps! :)

Step-by-step explanation:
Answer: Choice D) ![y = \pm \sqrt{x+5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cpm%20%5Csqrt%7Bx%2B5%7D)
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
![y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\](https://tex.z-dn.net/?f=y%20%3D%20x%5E2%20-%205%20%5C%5C%5C%5Cx%20%3D%20y%5E2%20-%205%20%5C%5C%5C%5Cx%2B5%20%3D%20y%5E2%20%5C%5C%5C%5Cy%5E2%20%3D%20x%2B5%20%5C%5C%5C%5Cy%20%3D%20%5Cpm%20%5Csqrt%7Bx%2B5%7D%20%5C%5C%5C%5C)

Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into
leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on
to make it a one-to-one function, to make the inverse a function. One possible domain restriction is
which would lead to the inverse function ![y = \sqrt{x+5}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%7Bx%2B5%7D)
