Answer:
y = r / (k+v)
Step-by-step explanation:
First, you use the distributive property and take out y: y(k+v)=r
Then you divide both sides by (k+v): y<u>(k+v)/(k+v)</u> = r/(k+v)
Finally you get y = r / (k+v)
Answer:
I. 1/5
II. -1/14
III. 2/9
Step-by-step explanation:
(i) (-3/5) + (-2/7)
Opening up the bracket;
3/5 - 2/5 =
Lowest common multiple (LCM) = 5
(3 - 2)/5
= 1/5
(ii) (-2/7) - (-3/14)
Opening up the bracket;
-2/7 + 3/14 =
Lowest common multiple (LCM) = 14
(-4 + 3)/14 = -1/14
(iii) (-4/ 9) = (- 2/3)
Rearranging the fraction, we have;
-4/9 + 2/3 =
Lowest common multiple (LCM) = 9
(-4 + 6)/9 = 2/9
It has a ratio of 1:4, meaning for every x, you'd get 4 from your y
B. congruent, im pretty sure
3/4 To find the slope of a line you need to do rise/run. you find two solid points meaning find two points are exactly on a intersection. Then you count up how much it needs to the point then count across to the next point
