Answer:
The slope is 3.
Step-by-step explanation:
So we have the equation:
This is in the slope-intercept form, where:
Here, m is the slope and b is the y-intercept.
From the original equation, m is 3 and b is -2.
In other words, our slope is 3.
So, the slope of the equation is 3.
And we're done!
Lets calculate the taxes that would been payed at each city:
city1 = 12000(7%) = 12000(0.07) = 840
city2 = <span>12000(8.5%) = 12000(0.085) = 1020
So if you go to city1 instead of city2, you save 1020 - 840 = 180
So you would save $180 from $12000, that is:
180 out of 12000
= 180/12000
= 0.015
and that is the 1.5%, that is what you could save</span>
According to the question,
Let,
"n" represent the number of miles semir walked.
"y" represent the number of miles sarah walked.
Now, according to the question,
y = 2n - 5 ........................this is your equation
Also,
the question states, each of them collect $18 in pledges for every miles walked.
Given,
Sarah collected $450
Now,
Using unitary method,
Sarah collects $18 for 1 mile
Sarah collects $1 for (1 / $18) mile
Sarah collects $450 for (1 / 18) * 450 mile
= 25 miles
So, Sarah walks 25 miles.
Now,
Taking equation,
y = 2n - 5
Since, y is the no. of miles sarah walked, we can write 25 in place of "y" So,
(25) = 2n - 5
25 + 5 = 2n
30 = 2n
30 / 2 = n
15 = n
Since, "n" is the no. of miles that semir walked, Semir walked 15 miles.
Answer:
I'm only in 7th grade
Step-by-step explanation:
The area of a square or rectangle is length × width. It changes because the answers to the multiplication problems are different. 3 × 5= 15, while 5 × 5= 25. Because one of the numbers you have to multiply are different in each problem, you'll have a different answer each time.
