Yuson must complete 45 hours of community service. she does 3 hours each day. which linear equation represents the hours yuson has left after x days?

y=45-3x

Step-by-step explanation:

we want y, which is the number of hours left. to find this, we take:

hours left=total # of hours required - hours worked/day

so:

y=45-3x

(because x could be any number: 2 days, 3 days, etc.)

the answer is simply just 6n add the two together as they have an n

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
