Answer:

3

Step-by-step explanation:

We are given that an expression

3a^2+9

We have to find the greatest common factor of 3a^2+9

In order to find the GCF we will find the factor of each term

3a^2=3\times a\times a

9=3\times 3

The common factor in both terms is 3.

Hence, greatest common factor of 3a^2+9 is 3.

Answer: 3

Write the equation of the line that passes through the points (2,0) and (1,-2)
Darya [45]

Answer:

y

=

x

−

Explanation:

First, we need to determine the slope of the line. The formula for determining the slope of a line is:

m

=

y

2

−

y

1

x

2

−

x

1

where

m

is the slope and the x and y terms are for the points:

(

x

1

,

y

1

)

and

(

x

2

,

y

2

)

For this problem the slope is:

m

m

=

Now, selecting one of the points we can use the point slope formula to find the equation.

The point slope formula is:

y

−

y

=

m

(

x

−

x

)

Substituting one of our points gives:

y

Solving for

y

to put this in standard form gives:
