Step-by-step explanation:
Ellipse is your answer, because if you plug the equation into a graphing calculator and identify the conic, the term ellipse is given-
Multiply both sides by the reciprocal (-8/7). You would get 40/7 or 5.71428571
Answer:
52.5
Step-by-step explanation:
7.50 x 7
2x + -11 = k
Reorder the terms:
-11 + 2x = k
Solving
-11 + 2x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '11' to each side of the equation.
-11 + 11 + 2x = 11 + k
Combine like terms: -11 + 11 = 0
0 + 2x = 11 + k
2x = 11 + k
Divide each side by '2'.
x = 5.5 + 0.5k
Simplifying
