I would say to divide 121.10 by 3
Here are the steps
put it into y=mx+b 4y=-5x+20
to isolate y divide both sides by y=-5/4+5
to find the xi
xi is when y=0 so plug it in to the equation 4y=-5x+20 4(0)=-5x+20
0=-5x+20 subtract 20 from each side -20=-5x the negatives cancel out 20=5x
to isolate x divide each side by 5 x=20/5
20/5=4
Answers:
m=-5/4
yi=5
xi=4
Equation = (y - 6)/(x - 4) = (5 - 6)/(1 - 4) => (y - 6)/(x - 4) = -1/-3 => 3(y - 6) = x - 4 => 3y - 18 = x - 4 => x - 3y = 14
Answer:
23 units
Step-by-step explanation:
Since both lines are chords, they're equal in length. This means we can set them equal to each other.
2x + 2x +2 = 15 + 8
This becomes 4x + 2 = 23.
Subtract two from each side to get 4x = 21.
Now divide by 4 to isolate x.
This makes x = 5.25.
Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units
Answer:
5
Step-by-step explanation:
-7 x 4 = -28
-7 x -6 = 42
-28 + 42 = 14
14 - 9 = 5
