Ming won 121 lollipops playing basketball at her schools game night. later, she gave four to each of her friends. she has 9 remaining. how many friends does she have?

She has 28 friends.

Step-by-step explanation:

Step 1- Subtract

121-9= 112

Step 2- Divide

112÷4=28

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
