Mike worked 2.25 hours on monday, 2.5 hours on wednesday, and 4.75 hours on saturday. he earns $6.20 and hour. how much did he earn in all?

$58.90

Step-by-step explanation:

All together mike worked 9 1/2 hours.

Multiply 6.20 by 9 and get 55.8

Divide 6.20 in half and get 3.10

Add those totals together and get $58.90

God Bless! :)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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)
