10. 12. 17<br>-- + -- + --<br>4. 6. 12​
SOVA2 [1]

Answer:

Step-by-step explanation:

I take it that what you mean is

10/4 + 12/6 + 17/12

Change all the questions so that their denominators are 12

10*3 / 4*3 + 12*2 / 6*2 + 17/12

30 / 12 + 24/12 + 17/12

(30 + 24 + 17)/12

71 / 12

5 11/12

Write an equation of the line shown in the graph in slope intercept form (y = mx + b). Show
Lena [83]

Answer:

y = 2x - 2

Step-by-step explanation:

Points on graph: (4,6) and (2, 2)

<u>Slope:</u>

m=(y2-y1)/(x2-x1)

m=(2-6)/(2-4)

m=(-4)/(-2)

m = 2

<u />

<u>Slope-intercept:</u>

y - y1 = m(x - x1)

y - 6 = 2(x - 4)

y - 6 = 2x - 8

y = 2x - 2
