Y=6x+11 2y-4x=14 I don't know the answer

Subtract 6x over so you have y - 6x = 11, and 2y - 4x = 14. This is a system of equations. Multiply the first equation by 2 to get 2y - 12x = 22. By subtracting the second equation from the first, you get 8x = -8. So, x = -1. Plug that into the first equation and y = 5. Plug both of those answers into the equation to check. 2(5) - 4(-1) = 14, 14 = 14. The answers y = 5, and x = -1 check out.

A store is holding a sale during which all items will be sold at 30% less than their marked prices. How much will a rug marked $
IceJOKER [234]

Answer:

Cost of rug during sale = $140

Step-by-step explanation:

Given

Marked price of rug in a store = $200

The store is holding a sale and offering a flat 30% less on marked price on all items

This means the sale price of all items would decrease by 30%

We can calculate the discount offered by taking out percentage discount of the marked price.

Discount offered on rug = 30% of Marked price =0.30\times200=\$60

The discount is then subtracted from the marked price to get the price of rug during sale.

∴ Price of rug during sale = Marked price - Discount =\$200-\$60 =\$140

If anyone knows the answer to this can you help me
Murljashka [212]

Answer:

<h3>             C.    y + 7 = -7(x - 3)</h3>

Step-by-step explanation:

The equation of a line is:

                          y - y₀ = m(x - x₀)

where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through

The product of slopes of two perpendicular lines is  -1

so if given lines slope is ¹/₇ them:

     ¹/₇·m = -1

        m = -7

(3, -7)     ⇒    x₀ = 3,  y₀ = -7

Therefore:

               y - (-7) = -7(x - 3)

                <u> </u><u>y + 7 = -7(x - 3) </u>
