What is 2/9 + 1/9 + 1/6 in fraction form
Nikitich [7]
We get all these to have the same denominators for all the fractions.

2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18

Now we can add all the numerators.

4/18 + 2/18 + 3/18 = 9/18

Simplify our answer by dividing both numbers by 3, then by 2.

9/3 and 18/3 = 3/6= 1/2

Our final answer is 1/2

The midpoint of a line segment is (−1,6) . One endpoint of the line segment is (4,−7) .
pogonyaev

Answer:

The other coordinate is (-6,19)

Step-by-step explanation:

m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

(4,-7)

(x,y)

[(4+x)/2 , (-7+y)/2] = (-1,6)

(4 + x)/2 = -1

4 + x = -2

× = -6

(-7 + y)/2 = 6

-7 + y = 12

y = 19

(Correct me if i am wrong)

Write an algebraic rule for the trend line. Report your rule in slope intercept form.
Tju [1.3M]

Answer:

y = 5x + 20

Step-by-step explanation:

Here, we want to find the slope intercept form equation of the trend line

The general form is:

y =

mx + b

b is slope and m

is the y-intercept

b = 20

To get the slope, we select any two points and use the slope formula

we have the points;

(10,70) and (5,45)

The slope formula is;

m = (y2-y1)/(x2-x1) = (45-70)/(5-10) = -25/-5 = 5

The equation of the line is thus;

y = 5x + 20
