Can you break down how to solve the problem ?
Montano1993 [528]

Answer:

A.  y  = \frac{-5x}{2} - 1

Step-by-step explanation:

Given parameters:

Equation of the line:

       5x + 2y = 12

Coordinates = -2, 4

Unknown:

The equation of the line parallel to this line = ?

  • To solve this problem, first, we need to find the slope of the given line.

     Every linear equation have the formula:  y = mx + c

     m is the slope of the line, c is the y- intercept

           5x + 2y = 12

 Express this equation as y = mx + c

                 2y = -5x + 12

                    y = \frac{-5}{2}x  + 6

The slope of this line is \frac{-5}{2}

  • Now, any line that is parallel to another will not cut or cross it at any point. This simply implies they have the same slope.

                  Slope of the line parallel is \frac{-5}{2}

  • Our new line will also take the form y=mx + c,

          Coordinates = -2, 4, x = -2 and y = 4

                     m is \frac{-5}{2}

Now let us solve for C, the y-intercept;

                     4 = - 2 x \frac{-5}{2}  + C

                      4 = 5  + C

                       C = -1

The equation of the line is therefore;

                 y  = \frac{-5x}{2} - 1

Plz help me :((((((​

Answer:

a and d = 32

Step-by-step explanation:

since ABC and DEF are similar m<A = m<D so you have the equation

5x + 12 = 8x

subtract 8x from both sides

5x + 12 -8x = 0

subtract 12 from both sides

5x -8x = -12

combine like terms

-3x = -12

devide by -3

x = 4

plug 4 into equation

5(4) + 12 = 8*4

20 + 12 = 32

32 = 32

A TV that usually sells for $192.74 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including
Mashutka [201]

Answer:

Step-by-step explanation:

If you are saving 25%, you are still paying 75%, right?  So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56

That's the cost of the TV on sale.  Now we need to find the sales tax amount, if the sales tax is .05 as a decimal.  We are paying $144.56 for the TV, which is 100% of the cost.  On top of that, we are paying another 5%.  So altogether, for the TV, we are paying 105% of the TV.  Therefore,

144.56(1.05) = $151.79
