Answer: Choice A
Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin
====================================================
Explanation:
The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location
B(2,1) means we move 2 units to the right and 1 unit up
C(3,4) means we move 3 units to the right and 4 units up
Each time we plot a new point, we always start at the origin.
Answer: The answer is (a) 3 × x = y and (b) x + x + x = y.
Step-by-step explanation: Let 'x' and 'y' denote the number of hours that Tina practised last month and this month respectively.
Then, according to the given information, we have
x = 15 and y = 45.
We can write the relation between 'x' and 'y' in two forms as follows -
(a) Multiplication form : 3 × 5 = 15 implies 3 × x = y.
(b) Addition form : 15 +15 +15 = 45 implies x + x + x = y.
Thus, the answers are (3 × x = y) and (x + x + x = y).

Answer:
I'm pretty sure it's undefined, sorry if this is wrong
Step-by-step explanation:
√72 = √4 * √18 = 2√18. Therefore her answer is incorrect.
√72 = √4 * √9 * √2 = 6√2.
Since √2 is approximately 1.41,
6 * 1.41 = 8.46 = 8.5 (nearest tenth).
