Answer:
7 rows
Step-by-step explanation:
There are 63 counters and they are in 9 columns, so in order to find the number of rows you have to divide 63 by 9 which comes out to be 7.
Step-by-step explanation:
The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.
For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).
We are between Options B and C.
In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.
In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.
Since we want 3 as the slope,
The answer is Option C.

Answer:
1/12 yard = 3 inches
Step-by-step explanation:
Each friend gets 1/3 of the ribbon, so ...
1/3(1/4 yd) = 1/12 yd
In inches, that is ...
(1/12 yd)×(36 in/yd) = 3 in
Each friend gets 1/12 yard, or 3 inches.
You can factor a parabola by finding its roots: if
has roots , then you have the following factorization:
In order to find the roots, you can use the usual formula
In the first example, this formula leads to
So, you can factor
The same goes for the second parabola.
As for the third exercise, simply plug the values asking
you get
Add 3 to both sides:
Divide both sides by 1.5:
