\dfrac{ 6 }{ 2+ \sqrt{ 7 } } - \dfrac{ 2 }{ 3- \sqrt{ 7 } }

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
