Answer:
x=12
Step-by-step explanation:
the 2 triangles are proportionately identical.
the larger one is 1/3 larger, so x would be 9 plus 1/3 of 9- 12
So after one month, FE (fitness explosion) costs $26 and Fitquest is $70; two months it's FE = $52, FQ = $85; three months it's FE = $78, FQ = $100; four months FE = $104, FQ = $115; five months FE = $130, FQ = $130. So answer C. 5 months is correct.
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
Answer:
1, -5
Step-by-step explanation:
sorry but i cant do no. 2 & 3 but here is number one
10x+5= 9x
10x-9x= -5
x= -5
Step-by-step explanation:
Let the required number be n
