A truck can fit 28 boxes in the back. If there are 3 trucks, we want to estimate the number of boxes that fit in the back of the three trucks. Which of the
following is the closest estimate to 28 so we can easily estimate the number of
boxes the three trucks hold?​

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:
