The two points on the coordinate plane represent jane's house and her friend's house. find the distance between the houses.           a. √  8  units   b. 2√  10  units   c. √  10  units   d. 2√  17  units

The answer is 2, we need to use the distance between point formula; I recommend you search in the internet another examples.

Step-by-step explanation:

We need to calculate the distance between points, so we need to use the formula d=

You can use Janes house (-5,-2) or friends house like (3,-4) point 1 or 2, it is the same way.

when we substitute in the formula

:

d =

d=

d= =

We need to reduce this result, so we need to find two number wich on of those can we solve the square root, if we divide 68/4 we find:

d=

And 4 has exact square root result, so the result in:

2

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
