Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2, 3), D(1, 2), E(4, 1), and F(5, 3)

alukav5142 [94]

Answer:

Option (B)

Step-by-step explanation:

CDEF is a quadrilateral having vertex C(2, 3), D(1, 2), E(4, 1), F(5, 3).

To prove that the given quadrilateral has a right angle, we will use the property of perpendicular lines.

$m_1\times m_2=-1$

where $m_1$ and $m_2$ are the slopes of the consecutive sides of the quadrilateral.

Since CD and DE are the consecutive sides of the quadrilateral, Carla is on the right track by finding the slopes of CD and DE.

Since Jonah is finding the slopes of opposite sides so he will not be able to use the property of perpendicular lines.

Option (B) will be the answer.

The table can be used to determine the solution to the system of equations, 2y − x = 8, and y − 2x = −5. Which solution can be u

SIZIF [17.4K]

The answer is (6, 7)

This is the system of two equations:
<span>2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6

Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5
y = 12 - 5
y = 7

Therefore, (x, y) = (6, 7)</span>
