Show that ABC is right triangle A(-7,-2), B(-3,-3) C(-4,-7)

Step-by-step explanation:

slope of AB = (-3 - (-2)) / (-3 -(-7) = -1/4

slope of BC = (-3 - (-7)) / (-3 -(-4) =  4/1

As the slopes of AB and BC are negative reciprocals of each other, they are perpendicular and therefore triangle ABC is a right triangle.

hi im bob : l

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
