Answer:

(2, -1)

Step-by-step explanation:

Whenever you reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.

(x, y) ⇒ (x, -y).

(2, 1) ⇒ (2, -1).

2) Two big bags of sugar plus one small bag of flour add up to a total of 12 kg.

alisha [4.7K]

Answer:

It's just a simultaneous equation

Step-by-step explanation:

Let a big bag of sugar = x

Let a small bag of flour = y

x+x+y = 12kg

2x+y = 12kg ... 1

x-y = 2kg ... 2

Add 1 and 2

2x+y = 12

x -y = 2

3x = 14

x = 14/3 = 4.66

Substitute value of x into 1

2(4.66)+y = 12

9.333 + y = 12

12 - 9.333= 12

y = 2.66
