(3,-5)(-8,4)
slope(m) = (4 - (-5) / (-8-3) = (4 + 5) / -11 = -9/11
point slope form : y - y1 = m(x - x1)
there will be 2 answers because there is 2 sets of points
using (3,-5)
y - (-5) = -9/11(x - 3) =
y + 5 = - 9/11(x - 3) <=== here is one
using (-8,4)
y - 4 = -9/11(x - (-8) =
y - 4 = -9/11(x + 8) <== here is the other one
Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
Answer:
50
Step-by-step explanation:
The total salary was $3650.
The base salary is $3500.
$3650 - $3500 = $150
He made $150 in commission.
He makes $12 commission for every $100 he sells.
$150/$12 = 12.5
He sold 12.5 amounts of $100.
Each $100 corresponds to 4 cases.
12.5 × 4 = 50
He sold 50 cases of coffee.
