We have:
The given sides must also be parallel i.e.
<em>Hence, (c) is correct</em>
Answer:
The answers is the option b .6
Answer: Second option.
Step-by-step explanation:
By definition, a Quadrilateral is a flat shape that has four straight sides.
A Rectangle is a Quadrilateral and has the following properties:
1. Its Opposite sides have the same length.
2. All its angles have equal measure (They are congruent).
3. Each one of those angles measure 90 degrees (An angle with this measure is also known as "Right angle").
4. Its opposite sides are parallel.
5. Its opposite sides have equal lenght.
In this case you can observe that the figure defined by the points E, F, G, and H has four sides, four right angles and its opposite sides are parallel and have equal length.
Therefore, based on the above, you can conclude that it is a Rectangle.
This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85
Answer:
Step-by-step explanation:
Solve for y to put the equation in slope-intercept form.
3x = 4y -4 . . . . . eliminate parentheses, collect terms
3x +4 = 4y . . . . . add 4
y = 3/4x +1 . . . . . divide by 4
The slope is the x-coefficient: 3/4.
The y-intercept is the constant: 1.
