So first, just simply solve both and then it become obvious. The expression 3-(2+5), you can evaluate what's inside the parentheses first and then your answer will be in the form of a integer: 3-(2+5) = 3-7 = -4 With the second one, your answer will be in the form of a simplified expression because we don't know what x is: 3x-(2x+5) = 3x-2x-5 = x - 5 Also, in the second one, you have to expand the parentheses in order to simplify it.

Well the first equation has a variable in it while the other one doesn't also the first expression if set equal to 0 is -2 while the other one is 5

Move the slider on the graph on the right to graph each function:

DedPeter [7]

Answer:

The domain is $x\geq 7$

The range is $y\geq 1$

Step-by-step explanation:

we have

$y=\sqrt{x-7} +1$

Find the domain

Remember that

The domain of a function is the set of all possible values of x

we know that the radicand of the function must be greater than or equal to zero

$x-7\geq 0$

solve for x

$x\geq 7$

therefore

The domain is $x\geq 7$

Find the range

Remember that

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

For x=7

The value of y is equal to

$y=\sqrt{7-7} +1=1$

The solution for y is the interval [1,∞)

therefore

The range is $y\geq 1$

Step-by-step explanation:

Water is the universal solvent" with a grain of salt (pun intended). Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Water's solvent properties affect all life on Earth, so water is universally important to all of us.
