How are patterns used to solve problems?

1 answer:

3 0

Patterns can help muliply and divide. For an example say your problem is 6x2 you can do 2+2+2+2+2+2. Or if your problem is 21 divided by 3 you could do 21-3 untill you get to zero and count how many time you had to subtract.

Help please!!!

Maslowich

y varies directly with x.

The constant of variation is k = 7

Step-by-step explanation:

We have to check whether both vary directly with each other or not.

Every pair of x and y will be considered one by one

If y varies directly with x, it should satisfy y = kx or k = yx

So,

For x= -2, y=-14

$-14 = -2k\\k = \frac{-14}{-2}\\k = 7$

For

x=3, y=21

$21 = 3k\\ k = \frac{21}{3}\\k = 7$

For

x=5, y=35

$35 = 5k\\ k = \frac{35}{5}\\k = 7$

As k is same for all pairs of x and y, it can be concluded that:

y varies directly with x.

The constant of variation is k = 7
