A weatherman was measuring the amount of rain two cities received over a week. City A received 3.74 inches while City B received 9.8 inches. How many rain fell during the week

13.54 inches

Step-by-step explanation:

We have been given that a weatherman was measuring the amount of rain two cities received over a week. City A received 3.74 inches while City B received 9.8 inches. We are asked to find the amount of rain during the week.

To find the amount of rain during the week, we will add the amount of rain in city A to amount of rain in city B as:

    3.74

 +9.8  

   13.54

Therefore, 13.54 inches of rain fell during the week.

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)
