Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line. Diamond is modeling addition. You may use the number line to help you arrive at your answer. * 10 + (-4) = 6 10 + (-14) = -4 10 - 4 = 6 10 + (-6) = 4

10 + (-14) = -4

Step-by-step explanation:

Given that,

Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.

For addition, she will add 10 and (-14) as follows :

10 + (-14) = -4

So, the crrect option is (b) "10 + (-14) = -4".

i can't solve unless i know what the line is

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
