prisoha [69]

Answer:

(1252+252)(52−1)

=(1252+252)(52+−1)

=(1252)(52)+(1252)(−1)+(252)(52)+(252)(−1)

=390625−15625+15625−625

=390000

divide by 39 is

=10000

The linear function graphed below represents the value of a comic book since Lucy purchased it. What was the value of the comic
zhuklara [117]

Answer:

C. $25

Step-by-step explanation:

We will find,

The slope of the function using \frac{y_{2}-y_{1}}{x_{2}-x_{1}}.

Taking the points (1,40) and (2,55).

Slope = \frac{55-40}{2-1}

i.e. Slope = \frac{15}{1}

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation y=mx+b,

We have, 40=15\times 1+b

i.e. b=40-15

i.e. b= 25

Thus, the equation of the linear function is y=15x+25.

<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>

So, the initial value of the comic book is when x= 0.

So, y=15\times 0+25 i.e. y= 25

Hence, the cost of the book when Lucy purchased it was $25.
