Answer:
x = 6
Step-by-step explanation:
Answer:
x = 9.09
Step-by-step explanation:
x - 7.9 = 1.19
Add 7.9 to both sides
x = 9.09
Answer:
A non-square rhombus is not a rectangle.
Step-by-step explanation:
A parallelogram is a quadrilateral (four-sided figure) that has two pairs of parallel sides.
A rectangle is a parallelogram with four right angles.
If a parallelogram does not have four right angles, then it is not a rectangle. However it is still a parallelogram, as it has two pairs of parallel sides.
The symbol shown is a ray. A ray has an endpoint and includes all points on a line in only one direction. That is why the symbol above the letters XY has a single arrowhead. Ray XY starts at point X; it includes all points on line XY between X and Y, and also point Y and all points on the line past Y. It does not include any point past X going in the direction from Y to X.
Y = (x^2 + 6x + 9) + 7 - 9
y = (x + 3)^2 - 2 - vertex form
Vertex (-3, -2)
