Sylvie finds the solution to the system of equations by graphing. y = {x + 1 and y=-x-1
Which graph shows the solution to Sylvie's system of equations?

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )
