10 batches, if you divide 20 by 2 then you get 10
Standard form is ax + by = c
y + 2 = -3x + 3 [distributed the -3]
3x + y + 2 = 3 [added 3x to both sides]
3x + y = 1 [subtracted 2 from both sides]
3x + y = 1 should be your answer
let's say the breakfast price was "x", so that's the 100%, and we know she gave 20% of that and that is 1.80.
so, 1.80 is 20%, and "x" is the 100%, what is "x"?
Answer:
E' (3, 1)
F' (-2, -1)
G' (-1, 4)
Step-by-step explanation:
The rule for rotating 180° is (x, y) ⇒ (-x, -y)
E is at (-3, -1). When the rule is applied, E' is at (3, 1)
F is at (2, 1). When the rule is applied, F' is at (-2, -1)
G is at (1, -4). When the rule is applied, G' is at (-1, 4)
