Answer:

0.44444444 or 4/9

Step-by-step explanation:

Since we know the value of x, we can rewrite the equation replacing the variables.

\frac{2}{3}^{2} + 3*\frac{2}{3} - 2

Now solve. While solving, remember the order of operations.

\frac{2}{3}^{2} + 3*\frac{2}{3} - 2 = 0.44444444 or \frac{4}{9}

Answer:

y = \frac{1}{3} x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y = 4 ( subtract 3x from both sides )

y = - 3x + 4 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-3} = \frac{1}{3}

Given c = 2 , then

y = \frac{1}{3} x  + 2 ← equation of perpendicular line

The cost of four sweats and two pairs of jeans is $140. The cost of two sweats and theee pairs of jeans is $150. Define the vari
posledela

Answer:

The system would be:

4x + 2y = 140

2x + 3y = 150

Step-by-step explanation:

If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.

4x + 2y = 140

2x + 3y = 150
