Answer:

B (1,1) & (2,-1)

Step-by-step explanation:

This is the answer because if a line was drawn through these 2 points the slope would be the same as line QR so therefore the two would be parallel.

Hope this helps :)

Answer: Your answer is B. (1,1) and (2, -1).

Step-by-step explanation: So if you look at the graph, and you look at point Q which is (-1,2), it goes up 2 from the Y axis and over 1 so that would give you 2 over 1. Now, if you look down at point R, (1,-2), it goes over 2 and down 1.

I hope this explains the question.

Answer:

Step-by-step explanation:

The easiest way to figure this out is to substitute in the variables. So for a, 2=-5+7 is correct, and 7=0+7 is correct as well. If you were to look at the other answers, you would see that the equation would not match up. Hope this helps!

8.4.9 On or off the line & Practice Problems

Andrews [41]

Answer:

Number of quarters → 15

Number of dimes → 2

Step-by-step explanation:

Let the number of dimes I have = y

And number of quarters = x

Since, I have amount in my pocket = $2

Therefore, 0.10y + 0.25x = 2

100(0.10y + 0.25x) = 100×2

25x + 10y = 200

5x + 2y = 40

2y = -5x + 40

y = -2.5x + 20 ---------(1)

Total number of coins in my pocket = 17

x + y = 17

y = -x + 17 ---------(2)

By using a graphing calculator we can graph these two lines (As attached)

Solution of the given system of equations will be the point of intersection of these lines.

Solution → (2, 15)

Number of quarters → 15

Number of dimes → 2

Alborosie

2.9 × 1.7 = 4.93

After 1.7 seconds, the puck's speed would be 4.93 meters per second.
