Answer:
y = -1/3x - 4 (slope-intercept form)
or
x + 3y = -12 (Standard form).
Step-by-step explanation:
The slope of the line = (-3 - (-2)) / (-3 - (-6))
= -1 / 3.
Using the point-slope form of straight line:
y - y1 = m(x - x1) we have:
y - (-2) = -1/3(x - -6))
y + 2 = -1/3(x + 6
y + 2 = -1/3x - 2
y = -1/3x - 4
In standard form (multiplying thru by 3):
3y = -x - 12
x + 3y = -12.
For this question, we want to find out what 9 / 12 equals as a percent
or x / 100. Therefore, we have a proportion here and can say:
9/12 = x/100
Now, at this point, we can cross multiply to get:
900 = 12x
Now, divide both sides by 12 to get x alone and find that:
x = 75 <==== FINAL ANSWER
so 9 is 12% of 75!
I hope that helps you out! Please let me know if you have any other questions!
There are 45 minutes in 3/4 of an hour.
N = 288
First, both 36 sqrt 2 and 24 sqrt 2 have the common sqrt 2, which means you can directly subtract them.
36 sqrt 2 - 24 sqrt 2 = 12 sqrt 2
12 is outside of the square root means it was a perfect square, thus 12*12 = 144.
There's still a 2 left in the sqrt, and 144 * 2 = 288.
Answer:
He hiked 9 1/8 miles
Step-by-step explanation:
First make the fractions like terms
Multiply 4 1/2 by 4/4 to get 4 4/8
Then add the fractions to get 9/8
9/8 is an improper fraction, make it 1 1/8
then add all the whole numbers 4+4+1=9
add the fraction 1/8 to 9= 9 1/8
