Answer:
you actually don't need a graph to be able to solve this equation. As long as you are given two data points, you can already solve for the linear equation. The most common way of writing linear equations is the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
Step-by-step explanation:
20,000,000 is the answer fren
B.
For all 3 to work together, they can paint 1 room per hour.
C.
John can paint a room at 1/4 of a room per hour.
Rick can paint a room at 1/5 of a room per hour.
Together they can paint a room at a rate of 9/20 of rooms per hour.
D.
1 = 1/4j + 1/5r + 11/20m (john, rick, molli)
E.
The least common denominator is 20
F.
1 = 1/4(0) + 1/5(0) + 11/20x
1 = 0 + 0 + 11/20x
1 = 11/20x
x = 1/(11/20)
x = 1 9/11
It will take Molli 1 hour and 49 minutes (60 x 9/11) to paint the room alone.
Tan^-1 (27/48)
x ≈ 29.36°
hope this helps!
20x + 9 = 14x + 15
<span>6x = 6 </span>
<span>x = 1 </span>
<span> So base angles are 20 + 9 means 29 degrees. To calculate the m of angle k, subtract 29 from 180: </span>
<span>180 - 29 = 151 degrees.
hope it helps</span>
