Use the pythagorean theorem since it's a right triangle. 12 + r is the hypotenuse and r and 24 are the legs so r squared + 24 squared = (12 + r) squared. Simplify and get r squared plus 576 equals r squared + 24r +144. Subtract r squared from both sides and then subtract 144 from both sides. You're left with 432=24r. Divide both sides by 24. r=18

-4 (2x - 3) > -28
Divide by -4 on both sides. Since we're dividing by a negative, we need to switch the sign.
2x - 3 < 7
Add 3 to both sides
2x < 10
Divide by 2 on both sides
x < 5
Answer:
total commission= $2,600
Step-by-step explanation:
Giving the following information:
He earns a 10 percent commission on the first $5,000 and 15 percent on all sales over $5,000.
<u>First, we need to structure the total commission formula:</u>
total commission= 0.10*x + 0.15*y
X= sales up to $5,000
Y= sales from $5,001 to infinity
<u>Now, sales for $19,000 sales:</u>
total commission= 0.1*5,000 + 0.15*14,000
total commission= $2,600
