Answer:

B. 5x+4

Step-by-step explanation:

Solving this is quite easy.

  2. Look at your bottom variables..since 7x and -7x are opposites they will cancel out! And same thing goes for y and -y.

Using the quadratic formula, plug a=2, b=3, and c=4 into the formula because the equation given can not be factored. 

x= -3(+/-) radical (3^2-4*2*2)/2(2)

therefore, x= (-3+ radical 7 i) / 4
                  x= (-3- radical 7 i )/ 4. 

the answer choice is 1.

The table below shows the number of skateboards sold at a skate shop each week for five weeks.
hammer [34]

Answer:

s = 22w

Step-by-step explanation:

We need to try this equation for all of the numbers in the table.

s = 22w

22 = 22 * 1

s = 22w

44 = 22 * 2

s = 22w

66 = 22 * 3

s = 22w

88 = 22 * 4

s = 22w

110 = 22 * 5
