I think it's :
Part A ; $30 * (x) + $13
$28 * (x) + $15
Part B ; so $30 * 4 + $13 = $133 vs.
$28 * 4 + $15 = $111 so that would mean company B Would charge the least amount.
Part C ; the difference between company a and company B prices is $22.

Upper Deck $9.25
Elena-2011 [213]

Answer:

13

Step-by-step explanation:

Purchase 2 upper deck tickets:

\$100-(2*\$9.25)=\$81.50

You can then buy 13 right field bleacher tickets before you reach deficit:

\$81.50/\$6.00=13.583

Because you cannot purchase a .583 of a ticket, the most you can buy is 13.

Show that the equation 2x + 3 cos x + e ^ x = 0 has a root on the interval [- 1, 0]
ExtremeBDS [4]

If <em>x</em> = -1, you have

2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0

and if <em>x</em> = 0, you have

2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0

The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
