A- it’s a Pythagorean triple(6, 8, 10)
Hello!
Let's check:
200 * 25% = 50
200 - 50 = 150
150 * 10% = 15
150 - 15 = 135
So, with the 25% and then an extra 10% off, the coat would cost $135.
200 * 35% = 70
200 - 70 = 130
So, Jenny's friend is incorrect, because that is not the same as a 35% discount.
Answer:
y = -5
Step-by-step explanation:
Isolate y:
-3x + 9y = -57
9y = -57 + 3x
y = (-57/9) + (3/9)x
Substitute for x:
y = (-57/9) + (3/9)(4)
y = (-57/9) + (12/9)
y = (-45/9)
y = -5
Y=-x²+5x
