Answer:
see below
Step-by-step explanation:
The graph opens upward if the sign of the squared term is positive. If that sign is negative, the graph opens downward. The first three equations open upward; the last opens downward.
The line of symmetry is the value of x that makes the squared term zero. Here, that is x=5 for all equations.
<u>y=2/3(x-5)^2</u>: A, D
<u>y=1/2(x-5)^2</u>: A, D
<u>y=3/4(x-5)^2</u>: A, D
<u>y=-4(x-5)^2</u>: B, D
Answer:
you are correct it is, 4a+100b
Step-by-step explanation:
Answer:
342
Step-by-step explanation:
x=5
72+72+18(5)+9+18 (5)+9=342
It should be 121, or +4 or -4 from that. But I am pretty sure it is 121
