Find the slopeplz this is due tommorro

3x - 45 - 15y = 3 • (x - 5y - 15)

I think its this and this is the slopes

Slope = 0.400/2.000 = 0.200

x-intercept = 15/1 = 15.00000

y-intercept = 15/-5 = 3/-1 = -3.00000

x = 15 + 5y, im pretty sure this is the answer. hope this helps!

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

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
