Answer 1
steps. first of record and gather like terms (-2xy^2+6xy^2)-4xy
next collect coefficient like terms (-2+6)x Xy^2-4xy
then calculate the sum or difference 4xy^2-4xy
A discrete function is a relation where the domain and the range take a specific discrete set of values and not the whole set of the real numbers.
In this case, it's okay to model the scenario with a line because all of the points will fall on the line. Only points corresponding to the integer domain values, however, actually represent the scenario.
Basically, a linear function that represents this situation serves as a prediction model to generalize this type of situation, but for this case, just the value inside the domain makes sense to this particular case.
Answer:
19 gallons
Step-by-step explanation:
We divide the total distance by the distance per gallon: 656/35. We get 18.74..., so Jon would need 19 gallons to travel 656 miles.
Answer:
-2
Step-by-step explanation:
Let's call the number x. The statement tells us that
x^2 - 10 = 3x, or
x^2-3x-10 = 0
Factoring:
(x-5)(x+2) = 0. Here, we see that there are two solutions: x = 5 and x = -2. So, the negative solution is x = -2.
