Answer:

Step-by-step explanation:
we know that
The tangency point on the x-axis is (r,0)
The tangency point on the y-axis is (0,r)
Find the slope of the line containing the points of tangency

Remember that the equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have


substitute

Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?
Let x = 49
(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147
Answer:
17%
Step-by-step explanation:
To calculate percent increase use
percent increase =
× 100%
increase = 28 - 24 = 4, hence
percent increase =
× 100% = 17% ( nearest percent )
E. (1, -5)
f. (-1, 5)
This can be solved by substituting -5x for y in the second equation.
