Is y=4/5x-8 and y=-5/4+3 perpendicular?

yes

Step-by-step explanation:

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x - 8 ← is in slope intercept form

with slope =

y = - x + 3 ← is in slope- intercept form

with slope = -

Now

× - = - 1

Hence the 2 lines are perpendicular

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
