What is the product of -1 3/8and 2 4/5
expressed as a mixed number?

-3 17/20

Step-by-step explanation:

-1 3/8 x 2 4/5 -> convert into mixed number

-1 3/8 = -11/8

2 4/5 = 14/5

-11/8 x 14/5 = -154/40 -> simplified to -77/2

(-11 x 14) (8 x 5)

  -154 .      40

Which equals to -3 17/20 as a mixed number

HOPE THIS HELPED!

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
