Find the distance between (2, 9) & (-1, 4). Round to the nearest tenth.

1.7

Step-by-step explanation:

To find the distance between two coordinates, use the formula .

y2 = 4, y1 = 9, x2 = -1, x1 = 2

Insert the values into the equation:

Simplify:

The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

Have a nice day!

i just took the test, the correct answer is .. 31.5 in.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
