Answer:
C. parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular
Step-by-step explanation:
Quadrilateral is referred to any four sided figure. Examples are; square, trapezium, rectangle, rhombus, kite ,parallelogram etc.
The given coordinates forms a quadrilateral ABCD with equal opposite sides and non-perpendicular adjacent sides. This is related to a quadrilateral known as parallelogram.
Therefore, the correct option is parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular.
Answer:
1/35
Step-by-step explanation:
Number of students born in a country other than the United States = 1/20
Also, 4/7 of 1/20 were born in Puerto Rico
Portion of the student body born in Puerto Rico is therefore = 4/7 of 1/20
4/7 x 1/20
Multiply through
4/140
1/35
Answer:
x = -9, y = 8
or,
(-9, 8)
Explanation:
Equation 1: 2x + 3y = 6
Equation 2: 4x - y = -44
To solve by substitution, make y subject for equation 2.
4x - y = -44
-y = -44 - 4x
y = 4x + 44
Substitute this y value into equation 1.
2x + 3(4x + 44) = 6
2x + 12x + 132 = 6
14x = 6 - 132
14x = -126
x = -9
Now, find y value:
y = 4x + 44
y = 4(-9) + 44
y = 8
To check for solution, insert x and y value in either equations.
2x + 3y = 6
insert values
2(-9) + 3(8) = 6
6 = 6
Hence, the solution is correct as both sides equal.
