Add. 7/8 + 5/6
solve step by step and give me a good explanation and then i will mark you brainliest

Step-by-step explanation: first you add the top number which is 7 + 5=12 then you add the below numbers which is 6+8= 14 so the answer is 12/14

7/8 x 5/5 = 40/35     5/6 x 8/8 =48/35 = 1 and something

Step-by-step explanation:

e

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

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
