If $24 represents the cost of the 5 used CDs, than your formula would be "24+5x" ,x being the amount of extra CDs you purchase.
24+5(6-5)
24+5(1)
24+5
=29
6 CDs would cost $29
I hope thats right, goodluck^^
Answer:
f(-2) = -1
Step-by-step explanation:
f(x) = -x^2 + 3
f(-2) means when x is -2
Shown in the graph below, the point of solution is: (-2,-1), so when x is -2 y is -1
Answer: $74
<u>Step-by-step explanation:</u>
Let C represent the cost of a coach ticket
Let B represent the cost of a business ticket
Washington: 150C + 50B = 18,450
NY City: 170C + 100B = 27,280
Solve the system using the Elimination method:
-2(150C + 50B = 18,450) → -300C - 100B = -36,900
1(170C + 100B = 27,280) → <u>170C + 100B = 27,280 </u>
-130C = - 9,620
<u> ÷ -130 </u> <u> ÷ -130 </u>
C = 74
Answer:
Step-by-step explanation:
<h3>Given</h3>
- m∠DXB = 70° 15' 12''
- m∠DXC = 30° 30' 20''
<h3>To find</h3>
<h3>Solution</h3>
<u>According to Angle Addition postulate:</u>
<u>Therefore</u>
- m∠CXB = m∠DXB - m∠DXC
- m∠CXB = 70° 15' 12''- 30° 30' 20'' = 39° 44' 52''
