I think it is 12 is the length for both sides because the difference from 20 to 15 is 1.33333... (I divided because i learned that reducing means dividing) so then i divided 16 by 1.33333... and i got 12

Which of the following exponential functions goes through the points (1, 12) and (2, 36)?
Savatey [412]

Answer:

The function through which given point passes is f(x) = 24 x - 12 .

Step-by-step explanation:

Given as :

The points are

x_1 , y_1 = 1 , 12

x_2 , y_2 = 2 , 36

now, slope of the line

Let The slope of line = m = \frac{y_2-y_1}{x_2-x_1}

Or, m = \frac{36 - 12}{2-1}

Or, m = 24

So The slope of line = m = 24

<u>Now, equation of line in point-slope form</u>

y - y_1 = m × (x - x_1 )

Or, y - 12 = 24 × (x - 1 )

or, y - 12 = 24 x - 24

or, y = 24 x - 24 + 12

or, y = 24 x - 12

or , f(x) = 24 x - 12

So, The function through which given point passes is f(x) = 24 x - 12 . Answer

The local skating rink pays Mary a fixed rate per pupil plus a base amount to work as a skating instructor. She earns $90 for
baherus [9]

Answer:The expressions for the payment made to Mary are,

        (Monday)      90 = 15m + b

        (Tuesday)     62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

                                   y = 4x + 30

For 20 students,

                                   y = 4(20) + 30 = 110

For Lisa's earnings,

                                    y = 8x + 15

Substituting 20,

                                   y  =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.
