5(h)+6=c? i think this would be the answer but not sure
Equation: x² - (x - y)² * y
Substitute values for x and y into equation.
-> (-5)² - ( (-5) - (-8) )² * (-8)
-> 25 - (-5 + 8)² * (-8)
-> 25 - (3)² * (-8)
-> 25 - 9 * (-8)
-> 25 - (-72)
-> 25 + 72
-> 97
What you do is you use the x and y and turn them into coordinate points and put them on the graph. The points would be…
(-2, 1)
(0,-1)
(2, -3)
I hope this helped!
1 guest = 500ml
7 guests = 500ml × 7 = 3500ml = 3.5litres
1 litre = $1.50
0.5 litre = $1.50 ÷ 2 = $0.75
3.5litres = $1.50 + $1.50 + $1.50 + $0.75 = $5.25
answer is $5.25
The answer to that equation is X= 1
