The x-values go up by 1: -2, -1, 0, 1, 2
The y values are always 3 times the previous value.
This is an exponential function.

y = a(b)^x

We need to find a and b.
Look at x = 0.
For x = 0, y = 4.

y = a(b)^x

4 = a(b)^0

Since b^0 = 1, this simplifies to

4 = a

Now we know a = 4. We have

y = 4(b)^x

Look at x = 1. For x = 1, y = 12.

12 = 4(b)^1

12 = 4b

b = 3

Now that we know a and b, we can write the function.

y = 4(3)^x

Now that you have the function written out, notice the following.
In the exponential equation we found, the number raised to x
is the number you multiply each y value to get the next y value.
In this case, each y value is 3 times the previous one, so you have 3^x.
The way you find "a" in the exponential equation is to look at the y-coordinate
when x = 0. When x = 0, b^x is 1, so b^x drops out, and you get "a" equal to
the y-value. In this case, when x = 0, y = 4, so "a" is 4.
With b = 3, and a = 4, you can quickly write:
y = 4(3)^x.

Jessica painted 3/4 of a room in 3/5 of an hour. How long will it take Jessica to paint the entire room?​
Snezhnost [94]

Answer:

<u>8/10 hours or 48 minutes.</u>

Step-by-step explanation:

State the problem as a rule of 3:

3/4 room --------- 3/5 hours

1 room ------------ x

x=\frac{(1room*\frac{3}{5} hours)}{\frac{3}{4}room}

x= 0.8 hours.

• How much is 0.8 hours in minutes?

0.8 * 60 = 48 minutes.

enyata [817]

Answer:

Some cities and towns are called municipali- ties. If a city government incorporates by citizen request, it is considered a municipal govern- ment. Cities in Texas operate under one of two types of law—general law or home rule. Small cities with populations of less than 5,000 may incorporate as a general-law city.
