Subtract thats how you get it
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
Additive inverses add to zero. the additive inverse of any number is just that number multiplied by -1. the additive inverse -1.9 is+1.9 because when you add them the result is zero

Step-by-step explanation:
Start by changing the dollars into cents.
2.07 dollars = 2.07 * 100 = 207 cents
1.64 dollars = 1.64 * 100 = 164 cents.
How much does 1 ounce cost for each?
207 cents / 48 = 4.3125 cents / oz
164 / 32 = 5.125
The better buy is the 48 fluid oz jar.
