15. I arrived at this conclusion because of the following:
29, 38 The difference is 9 between 29, and 38.
3, 8 The difference is 5 between 3, and 8.
14, 15 The difference is 1 between 14, and 15.
The pattern is 9-4= 5 and 5-4=1
So I have 9, 5, 1, a difference of 4.
Answer:
mhm
Step-by-step explanation:
The answer is MATHEMATICS.
Answer: Diameter = 4 cm
Step-by-step explanation:
20π = (π)(r^2)(5)
divide by 5 * π
4 = r^2
find the square root of both sides
2 = r
2 * 2 = d
4 = d
Answer:
(8,11)
Step-by-step explanation:
1st line
y = x+ 3
We need to find the equation of the other line
We have two points (3, 1) and (4, 3)
Slope
m = (y2-y1)/(x2-x1)
= ( 3-1)/(4-3)
= 2/1 = 2
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y =2x+b
Using the point (4,3)
3 = 2(4)+b
3 = 8+b
3-8=b
-5 =b
y = 2x-5
We have 2 lines
y =x+3 and y = 2x-5
Setting them equal to each other
x+3 = 2x-5
Subtract x from each side
x+3-x = 2x-5-x
3 = x-5
Add 5 to each side
3+5 =x-5+5
8=x
Now we can find y
y =x+3
y = 8+3
y=11
