Answer:

1.75 usd.

Step-by-step explanation:

I made the graphic to guide me. Th formula of the function that represents the problem is:

We choose two pairs, for example (2,3.5) and (4,7) and calculate the slope:

m= \frac{7-3.5}{4-2}=\frac{3.5}{2}= 1.75.

And we calculate the equation with the slope and one pair:

(y-7)=1.75(x-4)

y-7=1.75x-7

y=1.75x-7+7

y=1.75x.

Then, for x=1, this is one pen the price (the y value) is

y=1.75(1)=1.75, yu can see also the aproximation of the result with the graphic.

Help me PLEASEEEEEEEEEEEEE

The correct answer is 2.5 cm

Explanation:

In any polygon, the area refers to the total space occupied by the polygon. In the case of triangles, the area can be calculated by multiplying the base and height and then dividing the by 2. This means b x h / 2 = area of a triangle. According to this, the area of the triangle presented is 15

5 cm (base) x  6 cm (height) = 30 cm

30 cm / 2 =  15 cm (total area)

This also means the area of the rectangle is 15 considering both figures have the same area. Additionally, the area in rectangles is calculated by multiplying the length base by the width. This implies in the case presented 6 cm x w cm = 15 cm (total area), and you can determine the value of w by using a simple equation as

6 x w = 15

w = 15 / 6

w =  2.5

Also, you can know this is the correct value because 6 cm (length) x 2.5 (width) = 15 cm which is the correct area

alex41 [277]
When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.
