Answer:
The answer to your question is
Step-by-step explanation:
Data
4x - 8y = -16 ------------ (I)
x - 2y = - 8 ------------ (II)
a) Solve equation II for x
x = 2y - 8
Substitute x in equation I
4(2y - 8) - 8y = -16
8y - 32 - 8y = -16
8y - 8y = 32 - 16
0 = 16 The system has no solution because y was
cancelled.
b) When a system of equations do not have solution means that the lines are parallels and different.
Answer:
Step-by-step explanation:
You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.
Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.

Hello!
I believe the next term in the velocity sequence should be 28 cm.
Answer:
option a)
0.286
Step-by-step explanation:
Given that,
number of red pens in cup = 5
number of black pens in cup = 10
number of pen randomly selected = 3
There are 5 red pens and 10 black pens. So there are 5 + 10 = 15 pens in all.
probability of having all red pens = (5/15 x 4/14 x 3/13)
= 2/91
probability of having all black pens = (10/15 x 9/14 x 8/13)
= 24/91
probability that all pen are of same colour = 24/91 + 2/91
= 2/7
≈ 0.286
