Answer:
33/12 or 2.75
Step-by-step explanation:
6 1⁄6 - 3 5⁄12
37/6 - 41/12
74/12 - 41/12
<u>33/12 or 2.75</u>
Answer:
y = 9 inches
Step-by-step explanation:
Since the base angles are congruent then the triangle is isosceles with both legs being equal.
Using Pythagoras' identity in the right triangle
y² = 9² + 9² = 81 + 81 = 162 ( take the square root of both sides )
y = = = 9
I believe the first answer shown in the picture because y= mx + b so it's y=3x+30
hope this helps!
Answer:
The given function is not a proportional relationship
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
In this problem we have
This is the equation of the line in slope intercept form
where
e ---> represents her daily earnings
h ---> represents the number of hours she works
we have
The slope is equal to
The y-intercept is
Remember that
In a proportional relationship the y-intercept is equal to zero, because the line passes through the origin
In this problem, the y-intercept is not equal to zero, so this line don't pass through the origin
therefore
The given function is not a proportional relationship
