The scale on a map reads 1 cm = 250 km. How far is the actual distance if the map distance measures 3.8 cm?

950 km

Step-by-step explanation:

(cross multiply)

250(3.8)= 950

(divide both sides by 1)

950/1=950

can i get the link to the assignment?

step-by-step explanation:

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)
