-3 is the y intercept, so place a point there. The slope is 3/4. So from your -3 point, go up 3 and over 4. Make a point. Do that another time and also from the -3 intercept go down 3 and over left 4, the. you’ve got yourself a nice line.
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
Answer:
it's the answer A
Step-by-step explanation:
becAuse she is scared / nerv
You divide each total amount by the number of persons Popcorn: 48/6 = 8 Licorice: 3 X 48 = 144 144/6 = 24 So each person ate 8 ounces of popcorn and 24 inches of licorice laces
Y=(1/5)^x would be the only equation demonstrating decay of these
