Answer:
Third number is 12
Step-by-step explanation:
Let 
be common difference & 
be the third number. Set up the following equations:
Solve the simultaneous equation for x-term:
Let’s make sure that we get accurately answer. Substitute x = 12 in any equations which I’ll choose (1):
Now add each terms with common difference as 7:
-2+7 = 5
5+7 = 12
12+7 = 19
19+7 = 26
So our pattern is -2, <u>5</u>, <u>12</u>, <u>19</u>, 26. Since the question only asks for third number then the answer is 12
Y-y1=m(x-x1)
m=slope
y-(-2)= (2/3)(x-3)
y+2=2/3x - 2
Answer:
-4
Step-by-step explanation:
The slope is given by
m = (y2-y1)/( x2-x1)
= ( 13-5)/(-2 -0)
= 8/-2
= -4
Answer:
it equals x=10 so i guess it's B
Step-by-step explanation:
To find the circumference of a circle using its diameter you would use πd.
If π ≈ 3.14 and d = 10 units
3.14 * 10 = 31.4 units
The answer is approximately 31.4 units.
