quadratic formula is used to find "zeros" or the x-intercepts, the x values where y = 0
Answer:
<u>The number of copies that will make it worth the discount card is 250.</u>
Step-by-step explanation:
1. Let's review the information provided to answer the question correctly:
Cost per copy without discount = US$ 0.08
Cost per copy with discount = US$ 0.05
Cost of discount card = US$ 7.50
2. How many copies will make it worth the discount card?
For finding out this number of copies, we will use the following equation:
x = Number of copies that will make it worth the discount card
0.08x = 0.05x + 7.50
0.03x = 7.50 (Like terms)
3x = 750 (Multiplying by 100 at both sides)
x = 250 (Dividing by 3 at both sides)
<u>The number of copies that will make it worth the discount card is 250.</u>
Answer:
3 becuase y divided by x
Step-by-step explanation:
Answer / Step-by-step explanation:
500g - 300g = 200 {200 ÷ 500 = 0.4} <u><em>---- 300g pork</em></u>
0.4 × 150g = <u><em>60g tomatoes</em></u>
0.4 × 100g = <u><em>40g butter</em></u>
0.4 × 120ml =<u><em> 48ml water</em></u>
0.4 × 45g = <u><em>18g green chilli</em></u>
0.4 × 8og = <u><em>3.2og onion</em></u>
The answer would be that 2% is greater than 0.005
The reason is because 2% when changed to a decimal form it would be 0.020
