where is the question I don't see it
Answer:
There is no possible values for the number of whole hours walking dog
Step-by-step explanation:
Let x is the number of hours working as a babysitting (x ≥ 0)
Let y is the number of hours working as a walking dogs person (y ≥0)
We have a system of inequalities:
If Joseph worked 2 hours babysitting:
2+ y ≤ 9 <=> y ≤ 7 (y > 0) and
12x + 6y ≥ 90 <=> y ≥ 11
so there is no possible values for the number of whole hours walking dogs:
Hope it will find you well.
You then draw a right triangle having one angle with measure $\theta$ degrees and label the three sides. The longest side of the triangle is called the hypotenuse, the side opposite the angle $\theta$ is called the opposite side, the third side is called the adjacent side.
