Answer:

Only A

Step-by-step explanation:

For A, the y coordinate does represent the total cost of electricity for 4 hours. If you see the corresponding numbers on the chart, they both work. As for B, I used a proportional relationship with A to calculate if B works. Work: $120/4 hours. Divide both sides by 4 and u get $30 per hour, which means B is incorrect. C is incorrect because the answer is A.

saveliy_v [14]

Answer:

All the coordinates are changed to

(x, y) ⇒ (2x, 2y)

Step-by-step explanation:

Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.

To find -  Which answer choice correctly maps this dilation algebraically?​

Proof -

Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.

Now,

Let the coordinates be (x, y)

If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as

(x, y) ⇒ (ax, ay)

Here given , a = 2

So, all the coordinates are changed to

(x, y) ⇒ (2x, 2y)
