Pablo drove 23.1 miles to his aunt’s house, then drove 19.24 miles to his friend’s house. Which estimate can Pablo use to determine the distance he drove altogether?

Answers

Answer:

I think the answer is 42.

Step-by-step explanation:

I estimated 23.1 to 23 miles then I estimated 19.24 to 24 and added 23+19=42. But I don't know if that is correct because there was no specification if we round to the whole number.

In a translation, the y-coordinates of the pre-image increase by 8. What was the translation?8 units up

8 units down

8 units left

8 units right

Answers

y coordinates control up and down

increase by 8 means go up by 8

8 units up

So,

A translation is a transformation in which the figure is simply moved across space; the preimage is congruent to the image.

We are told that the y-coordinate of the preimage increase by 8. We know that the y-coordinates have to do with vertical movement on a coordinate plane. Since the y-coordinates increased by 8, the preimage was moved up 8 units.

The correct option is A.
