Answer:

8 Wallets cost 8 * 43 = 344 $

Step-by-step explanation:

The text provides us with the following system:

1. B = 2W + 58

2. 632 = 2B + 8W

Which can be re-evaluated to:

1.    B  - 2W = 58

2. 2B + 8W = 632

We multiply 1. with 2 and get:

1.  2B - 4W = 116

We then subtract 1. from 2. and get:

12W = 516 --(:12)--> W = 43

We then insert W = 43 into 1.:

B = 2*(43) + 58

--> B = 86 + 58 = 144

Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
nadezda [96]

Answer:

Tn = 4(-6)^n-1

Step-by-step explanation:

Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....

The sequence is a geometric sequence

Tn = ar^n-1

a is the first term

a = 4

r = -24/4 =144/-24

r = -6

Substitute

Tn = 4(-6)^n-1

Y= -3x^2-24x-46 write in vertex form
mario62 [17]

ANSWER

y= -3{(x + 4)}^{2}  + 2

EXPLANATION

The given function is:

y= -3x^2-24x-46

Factor -3 for the first 2 terms.

y= -3(x^2 + 8x)-46

We add and subtract the square of the coefficient of x.

y= -3(x^2 + 8x +  {(4)}^{2} )  - - 3( {4)}^{2} -46

Factor the perfect square trinomial.

y= -3 {(x + 4)}^{2} )  + 48 -46

The vertex form is:

y= -3{(x + 4)}^{2}  + 2
