a) {(-3, 1), (0, 4), (2, 6)}
b) {(0, 2), (-2, -6), (1, 5)}

d) {(2, 6), (-3, -7), (0, 4)}
Hey, amazing people can you help me? I will give 25 points and brainlist!
Answer: C, I think!
Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.
For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.
For B, pi to the second power over 3 equals 3.2897, so that’s not it too!
For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!
I’m only in 7th grade, so I’m sorry if it’s wrong!

Which statements are true about the ordered pair (−4, 0) and the system of equations?
{2x+y=−8
{x−y=−4
Select ALL correct answers.
The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.
The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.
The ordered pair (−4, 0) is a solution to the system because it makes both equations true.
The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.

(a) 77 people (b) 3,773 people
Step-by-step explanation:
(a) 3,850 x 2% = 77
(b) 3,850 - 77 = 3,773
Answer:

population is 3850
next year it will be 2% less
a) This is asking how many people will leave population
To find this
get
3850/100
38.5= 1 percent
so multiply by 2
it equals
77= 2percent
b) Then get the (77) which is 2% and
Subtract it from original amount
3850-77=
3773

Please help!! The expression 5(3 + 7) is a (pls explain how to do it)
Answer:
the first one is product and the second one is difference
just help me i dont get this
Answer:
No they are not equivalent
Step-by-step explanation:
its pretty simple. so you do the y/x method, y over x as a fraction, -4/1, -7/2, -10/3, -13/4. So after you set them up you divide them. -4/1= -4 -7/2= - 3.5 -10/3= -3.3 -13/4= -3.4 Then you see if the answers are equivalent ( if they have the same answer) So no they are not equivalent. I hope this helps.
