Answer:

8

Step-by-step explanation:

To solve an equation use PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction)

First solve for the parenthesis.

1+2(2*2)-1 = 1+2(4)-1

Then solve any multiplication/ division in order.

1+2(4)-1= 1+8-1

Then solve any addition/ subtraction in order.

1+8-1= 9-1= 8

The answer to the expression is 8.

How do I start this problem? I don't need help with the graphing part.
tamaranim1 [39]

Answer:

x = 6 , y = 0   (x , y) = (6 , 0)

x = 12, y = 3   (x , y) = (12 , 3)

x = 24, y = 9   (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0    (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3   (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9   (x , y) = (24 , 9)

A store is selling a black pair of shoes for $79.45 and a brown pair of shoes for $133.99. the black pair of shoes is marked up
Natalija [7]
Black Shoes:
Price = $79.45
Markup = 44% of 79.45 = 0.44 x 79.45 = $34.96
Price after Markup= $79.45 + $34.96 = $114.41

Brown Shoes:
Price = $133.99
Mark down = 21% of 133.99 = $28.14
Price after Mark down = $133.99 - $28.14 = $105.85

Difference in cost = $114.41 - $105.85 = $8.56

--------------------------------------------------------------------------------------------------------
Answer:  The black pair costs $8.56 more than the brown pair. (Answer B)
