The expression 8a+5c can be used to find the cost of an all you can eat buffet lunch for a adults c for children what is the cost of the lunch for 2 adults and 4 children

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

your answer is b.

x = 33.9

y = 65.6

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
