1) x = pounds of peaches purchased
2) y = total price for the peaches
3) the formula is: y = $2x
but I'm not clear on what you need to know...
After 1 hour >> 44 miles apart
after 2 hours >> 88 miles apart
after 2.5 hours >> 110 miles apart

To simplify the expression:
-(6 x^3 - 2 x + 3) - 3 x^3 + 5 x^2 + 4 x - 7
Start with - (6 x^3 - 2 x + 3) = -6 x^3 + 2 x - 3:
-6 x^3 + 2 x - 3 - 3 x^3 + 5 x^2 + 4 x - 7
Next, combine similar terms: -3 x^3 - 6 x^3 + 5 x^2 + 4 x + 2 x - 7 - 3 = (-3 x^3 - 6 x^3) + 5 x^2 + (4 x + 2 x) + (-7 - 3):
(-3 x^3 - 6 x^3) + 5 x^2 + (4 x + 2 x) + (-7 - 3)
-3 x^3 - 6 x^3 results in -9 x^3:
-9 x^3 + 5 x^2 + (4 x + 2 x) + (-7 - 3)
Combine 4 x and 2 x to get 6 x:
-9 x^3 + 5 x^2 + 6 x + (-7 - 3)
The operation -7 - 3 yields -10:
-9 x^3 + 5 x^2 + 6 x - 10
Factoring out -1 from -9 x^3 + 5 x^2 + 6 x - 10 leads to:
Final Answer: - (9 x^3 - 5 x^2 - 6 x + 10)
Answer:
In total, Henry requires 15 pints of paint.
Step-by-step explanation:
Henry starts with 2 pints of red and 3 pints of yellow to achieve a certain color, but he has already used 9 pints of yellow paint. Thus, this is represented by:
3 x 3 = 9 (yellow)
Since whatever is done on one side must also be applied to the other, we calculate the red paint:
2 x 3 = 6 (red)
Now we consolidate the amounts:
9 + 6 = 15. (Total red and yellow paint)
This leads to the conclusion that 15 pints are needed.
