6x + y = -2
y = -3x + 1
Substitute the value of y in first equation,
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1
Now, Substitute it in 2nd equation,
y = -3(-1) + 1
y = 3+ 1 = 4
Coordinates would be: (-1,4) Mark that point and join with origin.
Hope this helps!
1)
2(a + 3) = -12
Divide by 2
a + 3 = -6
Subtract 3
a = -9
2)
3(p + 2) = 18
Divide by 3
p + 2 = 6
Subtract 2
p = 4
3)
4(2r + 8) = 88
Dive by 4
2r + 8 = 22
Subtract 8
2r = 14
Divide by 2
r = 7
4)
2(3a + 2) = -8
Divide by 2
3a + 2 = -4
Subtract 2
3a = -6
Divide by 3
a = -2
5)
4(k + 3) = 4
Divide by 4
k + 3 = 1
Subtract 3
k = -2
I'm sorry, but the spinner that you choose does matter in this case.
For spinner A, there are 5 equal sections with a 1 being in only one of them as well. This gives you a

chance of landing on the number 1.
For spinner B, there are 6 equal sections with a 1 being in only one of them. This gives you a

chance of landing on the number 1 - a worse chance than if you were to use spinner A.
So for this question,
you have a better chance of landing on number 1 if you choose to use spinner A.
Answer:
A ≈ 78.54
Step-by-step explanation:
Area of a circle is A=πr^2
Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r
Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.
