<h2> the answer isthe value of x=20°</h2>
Use the y value in equation one and substitute it in equation two.
y=4x-3
y=-x-13
4x-3=-x-13
solve for x
add x to both sides
5x-3=-13
add 3 to both sides
5x=-10
divide both sides by 5
x=-2
Use x=-2 to solve for y in either equation
y=4x-3
y=4(-2)-3
y=-8-3
y=-11
(x, y) = (-2, -11)
Top right is the answer
Hope this helps! :)
Answer:
Square, Kite, Rhombus, Parallelogram, Trapezoid, Rectangle, Quadrilateral, Isosceles Trapezoid.
Step-by-step explanation:
Quadrilaterals are simply figures with exactly four sides. As you can see, the shapes listed all have four sides. Even an isosceles trapezoid (not to be confused with an isosceles triangle as the term is less commonly used then "isosceles triangle") as it is only a type of trapezoid.
