Ok, the equation should be like this:
Let c be the cost of each cookie
50c-20>60
When you solve it, c>1.6
Which means that each cookie should be sold for an amount more than $1.60

Natali5045456 [20]

Answer:

y = (-5/2)x + 1

Step-by-step explanation:

We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

I hope this helps! :)

Tim is thinking of two numbers. The quotient of the two numbers is 9. The difference of the two numbers is 48. The sum of the tw

Paladinen [302]

Let the two numbers be x and y, then
x - y = 48 . . . (1)
x + y = 60 . . . (2)

(1) - (2) => -2y = -12 => y = -12/-2 = 6
From (1), x - 6 = 48 => x = 48 + 6 = 54

Therefore, the two numbers are 54 and 6.

PLEASE HELP ASAP - use completing the square to rewrite the equation in vertex form : y=2x^2 - 12x + 25.

Musya8 [376]

Y=2(x-3)^2 +7 would be the way to rewrite this equation in vertex form.

Given y=-3/4x-2. What is the equation of the line that is perpendicular and has the point (-4,1)? Write answer in slope intercep

raketka [301]

Answer:

y=4/3+19/3

Step-by-step explanation:

When it asks for perpendicular it means your focusing on the slope.

Perpendicular means opposite of the current slope, so flip it and change the sign (-3/4 changes to 4/3). Next you will use the equation (y-y1)=m(x-x1)

y1=the y value given

x1=the x value given

m=your slope

(y-1)=4/3(x+4) Since the x point is minus a negative we get to change the sign to a positive. Next distribute the 4/3 to each term in the parenthesis.

y-1=4/3(x)+4/3(4)

y-1=4/3x+16/3 Now we add the one to both sides.

+1 +1 The one isn't in teh correct format to just add so first imagine it as 1/1. Now to get the bottom to have a 3 like in 16/3 we just multiply the top and bottom by 3.

$\frac{1}{1} x\frac{3}{3}=\frac{3}{3}$ Now we can add this to the 16/3

$\frac{16}{3} +\frac{3}{3}=\frac{19}{3}$ We can now put this back into our equation.

y=4/3+19/3
