These tables of ordered pairs represent some points on the graphs of lines s and t. Which system of equations is represented by lines s and t?

5x−2y=−157x+4y=20

3x+5y=−185x−9y=25

x+4y=−89x−y=21

2x−y=−142x+y=6

a) 7x=7

step-by-step explanation:

answer: 12   they all have at least 28 days

step-by-step explanation: haha

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
