Answer:
32% of the students did not have a pet.
Step-by-step explanation:
From the total students (100%):
- 1/4 of them had a dog only,
. Then, 25% had a dog only. - 20% only had a cat.
- 15% had multiple pets.
- 0.08=8% only had other than cats or dogs.
- <u>Adding up all these cases, we obtain the proportion of students that had at least one pet:</u>
. Then, 68% of the students did have a pet. - The rest of the students
, did not have any pet.
Multiplying-
Negative times negative is positive
negative times positive is negative
positive times positive is positive
Dividing-
positive divided by positive is positive
negative divided by positive is negative
positive divided by negative is negative
negative divided by negative is positive

Answer:
Step-by-step explanation:
x² + 4x - 1 - x =x² + 4x -x - 1 { bring the like terms together and add}
= x² + 3x - 1
Easy. your starting point is going to be at -2 on the y-axis. then from that point (-2) you're going to go down 1 and then over 2. then draw a straight line through those two points. The line should be a negative line.
