100y+x=230
150y+x=320
Y being the price per kilogram of steel bar, x being the added delivery fee.
If you were to solve the equaltion it would go x=230-100y by changing the first equation around the replacing that for the x int he second group, so you would get 150y+230-100y=320 or 50y=90 So Y=9/5dollars per kilogram. Or $1.8per kilogram, the delivery fee being $50

Answer:
Step-by-step explanation:
Coordinates of point B = (-6, -7)
<u>Transformation applied:</u>
1. Translation T(-2, 4)
- (x, y) → (x - 2, y + 4)
- B(-6, -7) → B'(-6 - 2, -7 + 4) = B'(-8, -3)
2. Reflection over y axis:
- (x, y) → (-x, y)
- B'(-8, -3) → B''(-8*(-1), -3) = B''(8, -3)
