Pretty sure it's not.... I think a function can't have any negatives
Answer:
the set of odd numbers that are divisible by 2
Given:
The equation is:
To find:
The number that belongs in the green box and another box.
Solution:
We have,
Subtracting 2x from both sides, we get
Adding 2 on both sides, we get
We need to divide both sides by 3 to isolate the variable x.
On dividing both side by 3, we get
Therefore, the missing values are 3 and 3, and the required equation is .
Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
Write - x^4+4x^3+5x^3-20x-40 ÷ x^2-5
Word form-
x raised to the power of four plus four x to the power of three plus five x raised to the power of three minus twenty x minus fourty divided by x raised to the power of two minus five
Numerical form-
x^4+4x^3+5x^3-20x-40 ÷ x^2-5
