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.

Solnce55 [7]
-5x + 5y = 40             -20x +20y =160               -5x + 5(8) = 40
4x + 3y = 24               20x +15y =120                -5x + 40 = 40

What’s the surface area
STALIN [3.7K]

Answer: 38 in.^{2}


Step-by-step explanation:

1/ Find the area of the triangular sides. (1/2 x 2 x 6 = 6 in.^{2} for each triangular side)

2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = 12 in^{2}. The rectangular side on the left is 2x3 = 6 in.^{2}, and the rectangular side on the right is 4x2 = 8 in.^{2}.

3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 12 in.^{2} + 6 in.^{2} + 8 in.^{2} + 6 in.^{2} + 6 in.^{2} = 38 in.^{2}

4/ You have your answer, now hope it helps ! :)
