Answer:
-8-8-8
Step-by-step explanation:
Answer:
(x - 8x)²
(x - 8x) (x - 8x).
using the identity
( a - b) ² = a² + b² - 2ab
a = x
b = 8x
x² + 64x - 16x²
Since the function is y = 3x, take any value of x and multiply it to get y.
If the y-coordinate is not 3 times the x-coordinate, it is not on the graph.
0 * 3 = 0, so (0, 0) is on the graph.
5 * 3 = 15, so (5, 15) is on the graph.
9 * 3 = 27, not 3, so (9, 3) is not on the graph.
7 * 3 = 21, so (7, 21) is on the graph.
1:1.67. You divide both sides by 1.8 to reduce the smaller measurement to 1.
1.8/1.8 : 3/1.8 = 1:1.67 and there you go.
