Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Less than 400 tickets in total were sold. L

miskamm [114]

Answer:

Tickets to sit on the bench (b) = 150

Tickets to sit on the lawn (l) = 200

Step-by-step explanation:

Tickets to sit on a bench (b)cost $75 each.

Tickets to sit on the lawn (l) cost $40 each

350 tickets had been sold

$19,250 had been raised through tickets sales

This forms a simultaneous equation:

b + l = 350 ... (i)

75b + 40l = 19,250 ... (ii)

Multiplying (i) by 40 and (ii) by 1 we get;

40b + 40l = 14,000 ... (i)

75b + 40l = 19,250 ... (ii)

Subtracting (ii) - (i) we get;

35b = 5250

b = 5250 ÷ 35 = 150

What is the vertex of the quadratic function given in the table?

likoan [24]

Answer:

The vertex is (-3,-2)

The vertex is basically the very top or very lowest, so you will notice how values around (-3,-2) are relatively the same in the y coordinate, but -2 is the "highest/lowest" so that's how you know it's a vertex.

If you try picturing the points in your head, you will see it make a U and at the bottom of the U is the vertex.

If x = -1, what is the value of y in the equation?y = 8x3 + 12x2 - 6x - 3

Bezzdna [24]

<h3>Answer: y = 7</h3>

Work Shown:

$y = 8x^3 + 12x^2 - 6x - 3\\\\y = 8(-1)^3 + 12(-1)^2 - 6(-1) - 3\\\\y = 8(-1) + 12(1) - 6(-1) - 3\\\\y = -8 + 12 + 6 - 3\\\\y = 7\\\\$

Explanation:

I replaced every x with -1. Then used the order of operations (PEMDAS) to simplify. Keep in mind that $(-1)^2 = (-1)*(-1) = 1$ and not $(-1)^2 = -1$
