Answers
Answer:
We need to solve this system of equations by substitution:
-6x-2y =20
3y=x
Yu can do it with the letter you decide
You can get the x from the second equation and replace in the first:
3y = x
-6x - 2y = 20 -> -6(3y) - 2y = 20 --> -18y - 2y = 20 --> y=-1
Then we can replace in the second one:
3*(-1) = x ---> -3 = x
So the answer is x = -3, y = -1
Solved by substitution method:

Answer:
area = 14.5 ft^2
Step-by-step explanation:
area = (6.5 x 2) + (0.5)(1.5)(2) (the base of the triangular shape is 8 - 6.5 = 1.5)
area = 13 + 1.5 = 14.5 ft^2

Lines a and b are cut by transversal f. At the intersection of lines f and a, the top left angle is 96 degrees. At the intersection of lines b and f, the bottom right angle is (6 x minus 36) degrees. What must be the value of x so that lines a and b are parallel lines cut by transversal f? 10 20 22 32
Answers
Answer: 22
Step-by-step explanation:
Lines a and b are cut by transversal f.
Then from the given information,
[tex]6x-36=96[/tex] [ If two parallel lines are cut by a transversal then, the alternate exterior angles are equal. ]
[tex]\Rightarrow\ 6x=96+36\\\\\Rightarrow\ 6x=132\\\\\Rightarrow\ x=\dfrac{132}{6}\\\\\Rightarrow\ x=22[/tex]
Hence, the value of x so that lines a and b are parallel lines cut by transversal = 22

In the triangle below, which of the following best describes Xy?
Y
40°
40°
A. Angle bisector
B. Median
C. Altitude
O
D. Perpendicular bisector
Answers
Answer:
option A is correct answer of this qn
The word which best describes XV is Angle Bisector.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given is a triangle XYZ.
Here a line segment is drawn from the vertex X to the opposite side YZ.
Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.
Here, it is not given that, YV = ZV, so it is not median.
Altitude is the perpendicular line joining the vertex to the opposite side.
Here, it is not given the line is perpendicular. so it is not altitude.
Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.
Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.
So the line is angle bisector.
Hence the correct option is Angel Bisector.
