Write each fraction in simplest form.

12 over 48

6 over 15

Answer:

if x+y=5, then x=5-y

so x-4y=-10

5-y-4y=-10

5-5y=-10

-5y=-15

y=3

x=5-y

x=5-3

x=2

x=2; y=3

A trend line is a line that indicates the tendency of a graph; in other words, is the line that shows the apparently direction of a group of points on a graph. There are various types of trend lines; let’s check them:

Linear

Linear trend lines are used when the points on your graph follow a straight line pattern, which means that something is increasing or decreasing at a fixed rate (the slope of the straight line).

Logarithmic

Logarithmic trend lines are curved lines used when the rate of change increases very quickly and then settles down.

Polynomial

Polynomial trend lines are curved lines used when the data oscillates (change in direction from increasing to decreasing or vice versa).

Power

Power trend lines are curved lines used when you have a positive set of data that increases at a specific rate.

Exponential

Exponential trend lines are curved lines used when you have a set of data that increase or decreases at increasingly or decreasingly higher rates.

Moving averages

Moving averages are used when your data that varies a lot. They can be straight lines, curved lines or a combination of both.

As you can see, all trend lines are either straight lines or curved lines; therefore, the correct answer is a. curved lines or straight lines
