(5 2/7 −1 1/2 )∙(1− 14/53 )

I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )

Convert mixed numbers to improper fractions 5 2/7 = 37/7:

(37/7-1 1/2) * (1- 14/53

Convert mixed numbers to improper fractions 1 1/2 = 3/2:

(37/7-3/2) * (1- 14/53

Join 37/7-3/2 = 53/14

53/14(-14/53+1)

Join 1-14/53 = 39/53

53/14 * 39/53

Cross-Cancel 53:

39/14

Your Answer As A Improper Fraction---> 39/14

Your Answer As A Mixed Number---> 2  11/14

plz mark me as brainliest :)

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

it’s supposed to be -4+45=41
