How do I multiply a decimal with another decimal?

You can use multiplication normally. But then you must add the decimals

Step-by-step explanation:

Lets do 24.56 x 32.78

It would equal 8050768 without decimal points

But now we must add the decimal points in, count the amount of numbers that appear after the decimal, which is 4

So 8050768 = 805.0768

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)
