Answer:
7
Step-by-step explanation:
also why is 78 there? a factor means in that range
In the point (x, y), if x=0, then the point is on the y axis.
If y=0, the point is on the x axis
If both x and y are positive (greater than 0), the point is in quadrant 1
If x is negative (less than 0) and y is positive (greater than 0), the point is in quadrant 2
If both x and y are negative, the point is in quadrant 3
If x is positive and y is negative, the point is in quadrant 4
Taking (-3, 2), since 3 has a - sign before it (and nothing else), it is negative. Since the x value comes first, this means that x is negative. Since it simply states "2" for the y value, it is positive. As x is negative and y is positive, we know that the point is in quadrant 2.
I challenge you to do this on your own - good luck, and feel free to ask with further questions!
Answer:
3 pens.
Step-by-step explanation:
x+y=7 where x is # of pens and y =# of pencils
3x + 2y= $18
from first equation, x=-y+7 so substitute that into other equation
3(-y+7)+2y=18
-3y+21+2y=18
-y=18-21
-y=-3
y=3
now replace y =3 into first equation
x+3=7
x=4
Answer: 604/25=24 4/25
Step-by-step explanation:
9/5*81/5=729/25
729/25 - 5= 729/25 - 125/25=604/25
