Answer:
x = 5/2 thì y = 35 và x = -5 thì y = 5
Step-by-step explanation:
thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:
4x + 25 = 2x ^ 2 + 9x
⇒2x ^ 2 + 5x - 25 = 0
⇒ x = 5/2 và x = -5
thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35
thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5
Answer:
A) $29.68
B) $5.60
Step-by-step explanation:
<u>Part A Explanation)</u>
To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>
<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>
28.00 + (28.00 * .06) = 29.68
<u>Part B Explanation)</u>
This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.
28.00 * .20 = 5.6
<em>.20 out of 1 is 20%</em>
