Tile costs $28 per square meter. how much will it cost to cover the counter top with new tile?( 4.36 square meters)
28 x 4.36 = $122.08
The slope intercept form is y=mx+b
in this case y=-x
y=(-1)x + 0
so the slope m=-1 and y-intercept which is b is 0
Answer:

Step-by-step explanation:
4x - 6y = 8 ⇔ - 6y = -4x + 8 ⇔ y = 4/6x - 8/6 ⇔ y = 2/3x - 4/3
The expression that can be used to represent x is not shown.
x is the price of the shoes
5% commission on every pair of shoes sold. $1.00 is the value of the commission received.
$1/5% = 1 / 0.05 = 20
The price of the shoes is 20.
