Answer:
2) no change to the graphs
3) x = 1.47, y = 4.71
coordinates at intersection = (1.47, 4.71)
Step-by-step explanation:
4x + 3y = 20
3x - 2y = -5
2) Declan's way:
8x + 6y = 40
9x - 6y = -15
No change in graphs
4x + 3y = 20, 3y = 20 - 4x multiply by 2: 6y = 40 - 8x
3x - 2y = -5, 2y = 3x + 5 multiply by 3: 6y = 9x + 15
then:
40 - 8x = 9x + 15
simplify:
add 8x to each side:
17x + 15 = 40
subtract 15 from each side:
17x = 25
x = 1.47
3y = 20 - 4x
substitute for x:
3y = 20 - 4(1.47)
reduce:
3y = 14.12
y = 4.71
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g
