Suppose a line that appears parallel to side BC of AABC intersects sides AB and AC at points X and Y respectively, and Ax = . How
can you determine if the line is or is not parallel to BC ? Explain. (4 points)

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

hm let me think hm think think hm think yes

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
