Answer:
The answer is below.
Step-by-step explanation:
Answer:
h=(c/25)-4
Step-by-step explanation:
c-100 = 25h. "/25"
(c/25)-4 = h
x = 4 and y = 9 and z = 7
x(y + z - 32) = 4 · (9 + 7 - 32) =
= 4 · (16 - 32) = 4 · (-16) = <u>-</u><u>6</u><u>4</u>
(5)x19.80=y
(5)x19.80=99
Because the only info given is 19.80 and 5, those are the only definate variables-the total cost is unknown so it is represented by y. To find the total cost, one must multiply the cost of each tickets with how many tickets were bought, represented by (5)x19.80 [the 5 is in parenthesis because it is the independent variable, meaning it changes]. When multiplied together, the equation equals 99, or $99.
Axis of Symmetry: x = -b/2a
Vertex: y = Ax² + By + c
