what- A triangle is formed by the intersection of the lines y = 2x + 4, y = -x – 2, and x = 1.Is the triangle equilateral, isosceles, or scalene Graph the lines on grid paper to find the vertices of the triangle?
scalene
The sum of the length and width of a rectangle is 19 inches the length is 1 less than twice the width find the length and width of the rectangle?
Let x = length and y = width Then x + y = 19 Therefore x = 19 - y Also x = 2y - 1 (the length is 1 less than twice the width) So as x = x then 19 - y = 2y - 1 Therefore 3y = 20 which makes y = 6.666667 inches (width) and x = 19 - 6.666667 = 12.333333 inches (length) Twice the width would be 2 x 6.666667 = 13.3333333 inches and 1 less will be 12.3333333 inches (as above)
Triangle 2 is a reflection over the line x equals y of triangle 1?
x=y is the diagonal line which runs through 0,0 so all you have to do is reflect the triangle on the diagonal line. hop that helps :)
The length of a rectangle is three times its width If the perimeter of the rectangle is 48?
The perimeter of a rectangle is equal to 2*length + 2* width. In this case, we will say 2x + 2y = p = 48. Since the length is equal to 3 times the width, the equation now becomes p = 6*y + 2*y, or just p = 8y. Now since p =48, y must equal 6. And since the length is three times the width (y), the length is 18.
The length of a rectangle is 3 meters more than 2 times the width the area is 77 meters squared what is the length and width?
Let's call the lendth x and the width y x = 2y + 3 xy = 77 That is what is know in the trade as a simulataneous equation Because we have an x on its own lets substitute that equation into the second. (2y + 3)y = 77 2y2 + 3y = 77 2y2 + 3y -77 = 0 (2y - 11)(y + 7) = 0 y = 5.5 or -7 You don't get recangles with negative lengths so: y = 5.5 We can then substitute that into one of the equaitons to find x x = 2y + 3 x = 2*5.5 + 3 x = 14 So the length is 14 and the width is 5.5
what- A triangle is formed by the intersection of the lines y = 0, y = -3x + 3, and y = 3x + 3.Is the triangle equilateral, isosceles, or scalene Graph the lines on grid paper to find the vertices of the triangle?
isosceles
How do you find the perimeter of a triangle with x and y coordinates?
a circle
What formula would you to find the area of a square?
x=length of square x multiplied by y = area of square y=width of square width multiplied by length = area
How do you find the angle of a right triangle?
Need more information... All you say is how do you find the angle of a right triangle... Well 90 + X + Y = 180 90 Being the 90 Degree Angle 180 Being the entire degree measure of a triangle. X+Y is simply used to find the value of on you if you have the other. Lets say 30 is X 90 + 30 + Y = 180 120 + Y = 180 Y = 60

How do you find a missing angle of a right triangle given two sides?
180-x-y (x and y are the sides you already know) there are 180 degrees in a triangle. The remaining # is the last angle
Where would you position a triangle on a coordinate plane if you wanted to find the area of the triangle?
