Erica earned $145 by selling x hot dogs and y spring rolls. Each hot dog costs $2.50 and each spring roll costs $1.75. The relationship can be
represented by the function 2.50x + 1.75y = 145.
Use the x- and y-intercepts to graph the function.

c

step-by-step explanation: easy math

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
