Evaluate. 8/13 ÷ 2/3 a.16/39 b.12/13 c.11/15 d.24/13

  B.  12/13

Step-by-step explanation:

The answer choices suggest that you intend the problem to be interpreted as ...

  (8/13)/(2/3) . . . . . parentheses are required

  = (8/13) × (3/2) = (8·3)/(13·2) = (8·3)/(2·13)

  = (8/2) × (3/13) . . . . making use of the associative property

  = 4 × 3/13 = 12/13

Your calculator can help with these. You do need to get the parentheses right.

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
