7) 5 + 1/8 [-] 2 - 1/4
5 - 2 which equals to 3

Now, 1/8 - 2/8 = negative -1/8
Therefore, your answer for this question would have to be : 2 7/8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
8) 7 1/3 = 22/3
18 5/6 = 113/6
7 3/8 = 59/8

Answer:

option C

f(x)=-\sqrt{x+3}+8

Step-by-step explanation:

we have

f(x)=-2\sqrt{x-3}+8

using a graphing tool

see the attached figure N1

The range is the interval--------> (-∞,8]

y\leq 8

case A) f(x)=\sqrt{x-3}-8

using a graphing tool

The range is the interval--------> [-8,∞)

y\geq -8

case B) f(x)=\sqrt{x-3}+8

using a graphing tool

The range is the interval--------> [8,∞)

y\geq 8

case C) f(x)=-\sqrt{x+3}+8

using a graphing tool

The range is the interval--------> (-∞,8]

y\leq 8

case D) f(x)=-\sqrt{x-3}-8

using a graphing tool

The range is the interval--------> (-∞,-8]

y\leq -8
