Put a dot on -7 and -1 so the slope is 3 over 2x for the first inequality and the y is -1 do rise over run for each the slope for second is 1 over 1 put a dot for both on y axis (:
Answer:
General Solution is and the particular solution is
Step-by-step explanation:
This is a linear diffrential equation of type
..................(i)
here
The solution of equation i is given by
we have
Thus the solution becomes
This is the general solution now to find the particular solution we put value of x=2 for which y=6
we have
Thus solving for c we get c = -1/2
Thus particular solution becomes
Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius ) , then
x² + y² = ( )² , that is
x² + y² = 249 → D
The shape that best describes forest park is parallelogram. The correct answer is Option C).
<u>Step-by-step explanation</u>:
<u><em>step 1</em></u><em> :</em>
The two streets Oak and Maple are parallel.
The two streets Jefferson and Washington are parallel.
<u><em>step 2</em></u><em> :</em>
These parallel lines are intersecting each other.
<em>The properties of intersection of parallel lines:</em>
- In the figure the lines are not shown as right angle, so they are not perpendicular (angle ≠ 90° and the lines have same slope)
- The alternate interior angles are equal.
<u><em>step 3</em></u><em> :</em>
<em>The properties of parallelogram are:</em>
- Opposite sides are parallel with same slopes.
- Opposite angles are congruent (same).
<u><em>step 4</em></u><em> :</em>
- The parallel lines of the streets make the opposite sides of the parallelogram.
- The interior angles of parallel lines are the opposite angles of the parallelogram.
Thus, the shape forest park best describes parallelogram.
