To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:
14÷4
=3.5miles
Each of them have to run 3.5 miles.
To prove the answer, we can multiply it by 4 to see if it is the original distance:
3.5 x 4
=14miles
Therefore 3.5 is the answer.
Hope it helps!
The form is
a+bi
a is the real partt
bi is the imaginary part
add complex parts with complex and real with real
treat 'i' as x
remember, i=√-1 so i^2=-1
-2i(9-3i)-1(6-10i)
distribute
-18i+6i^2-6+10i
-18i-6-6+10i
-18i+10i-6-6
-8i-12
-12-8i
answer is -12-8i
Answer:
2.66
Step-by-step explanation:
Answer:
0.538
Step-by-step explanation:
There are 13 balls in the urn
- 7 are black and 6 are red
There are 7 chances out of 13 to pick a black ball
- 7/13
- 7 ÷ 13 = 0.53846.....
Round and get:
Answer: Choice A) y = 2x
slope = 2, y intercept = 0
===================================================
Explanation:
We can see this by noting that each y coordinate is simply doubled that of the x coordinate.
- x = 1 doubles to y = 2
- x = 2 doubles to y = 4
So in general, x doubles to 2x to get the y coordinate. Therefore, y = 2x.
----------
Alternative method:
A more thorough step by step process would have us first finding the slope
m = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(2 - 1)
m = 2/1
m = 2 is the slope
Use this slope value along with one of the points to find b. I'll use the point (x,y) = (1,2)
So,
y = mx+b
2 = 2*1+b
2 = 2+b
2-2 = b
0 = b
b = 0 is the y intercept
We go from y = mx+b to y = 2x+0, which simplifies to y = 2x
