Last month maria hiked the 5-mile mountain trial a number of times and she hiked the 10-mile canal trial several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trial. is she hiked a total of 90miles , which equation can b used to find the number of times maria hiked each trail ?

Step-by-step explanation:

x + y = 90 5x – 10y = 90    90 – 10y = 5x 90 + 10y = 5x

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
