First you would find your domain which is your x the you find your range which is the y then you get the answer -2 <x_<3 which in your case is option A.

The domain is ur x values....so going along the line on ur x axis.....open circle means no equal sign....closed circle means there is an equal sign...
-2 < x < = 3

3) What percent of 104 hours is 20 hours?

Strike441 [17]

x = percentage (eg: if x = 3 then this represents 3%)

x/100 = decimal form of the percentage (eg: if x = 3 then x/100 = 3/100 = 0.03)

The equation to solve is

x/100 = 20/104

Cross multiply to get

104x = 100*20

104x = 2000

Then divide both sides by 104 to isolate x

104x/104 = 2000/104

x = 2000/104

x = 19.230769

x = 19.23

So the answer is approximately 19.23%

Answer:

d(t)=-10t-520

Step-by-step explanation:

First you have to find the gradient (m) using the formula $m=\frac{d(t)2-d(t)1}{t2-t1}$

using the two points you have been given: 1(3,-550) and 2(8,-600)

so you substitute these points into the equation $m=\frac{-600+500}{8-3}$

m=-10

Now that you have found the m-value you need to find the b-value by using one of the points you already have, I will use Point 2 (8,-600), and substitute it into the equation and solve

d(t)=-10t+b

-600=-10*8+b

-600=-80+b

-520=b

Therefore, the equation is d(t)=-10t-520

500% increase write each percent as a fraction and as a decimal

Bogdan [553]

As a decimal its 5.00 but u could just drop off the zeros that would be 5 still right as a fraction it would be 5 over 10 when u simplfy it would be 1 over 5
