2x+6>2and 5x< 6 + 2x

LiRa [457]

Answer:

-2 > x < 2

Step-by-step explanation:

Given that:

2x + 6 > 2

Subtracting 6 from both sides:

2x + 6 -6 > 2-6

2x > -4

Dividing by 2 on both sides:

x > -2

For second equation:

5x< 6 + 2x

Subtracting 2x from both sides:

5x - 2x < 6 + 2x -2x

3x < 6

Dividing by 3 on both sides:

x < 2

Result: -2 > x < 2

1) For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.

Gelneren [198K]

Answer:

Yes, "y" varies directly with "x".

The equation is: $y=1.375x$

Step-by-step explanation:

By definition, Direct variation equations have the following form:

$y=kx$

Where "k" is the Constant of variation.

If you solve for "k", the equation is:

$k=\frac{y}{x}$

Then, given the table provided in the exercise, you can know if "y" varies directly with "x" by finding the quotient of the correspoding values of "x" and "y":

- Dividing $y=11$ by $x=8$ you get:

$\frac{11}{8}=1.375$

- Divide $y=22$ by $x=16$ :

$\frac{22}{16}=1.375$

- Dividing $y=33$ by $x=24$ :

$\frac{33}{24}=1.375$

Since the quotient is constant, then "y" varies directly with "x" and the the Constant of variation is:

$k=1.375$

Therefore, the equation for the Direct variation is:

$y=1.375x$
