Equation parallel to y = -x is y=-x+k
so 4.5 = -7 + k so k - 11.5
Equation is y = -x + 11.5
Answer:
A = 63 m^2
Step-by-step explanation:
The area of a parallelogram is bh
A = bh
The base is 9 and the height is 7
A = 9*7
A = 63 m^2
Answer:
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).
Ordering tickets online cost $10 plus additional service charge of $8.
Therefore total cost,C = 10t + 8
Buying tickets at the door cost $12
Therefore, total cost,C = 12t
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Answer:
(-3,-4)
Step-by-step explanation:
The vertex is the minimum or maximum or a parabola.
