Answer:

y = 5x - 7

Step-by-step explanation:

We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.

10x -2y = ...

Removing a common factor of 2 gives ...

5x -y = 5(2) -(3) = 7 . . . . using (x, y) = (2, 3), we can find the constant

Solving for y, we get ...

5x -7 = y . . . add y-7

y = 5x -7 . . . write in the desired form

a school bake sale earned over $25 from selling cookies, which cost $3 each. how many cookies did they sell? identify the number

SSSSS [86.1K]

It said the sale earned OVER $25 from selling cookies at $3 dollars each so if we let r=revenue , p=price per cookie and c=number of cookies sold:

pc>r and since p=3 and r=25

3c>25 divide both sides by 3

c>25/3

Since cookies are quantized units, they must be integers so:

c>8 1/3

c≥9 or in interval notation

c=[9, +oo)
