A 2-column table with 5 rows. Column 1 is labeled x with entries negative 4, negative 2, 0, 2, 4. Column 2 is labeled y with entries 19, 16, 13, 10, 7. Use the values in the table to determine the slope. m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction

i got 86 for this

hope this !

if you need an explanation just ask

answer: procent 54 wynosi 33,33%

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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
