Which choice is equivalent to <br> 2^7 divided by 2^-3
harkovskaia [24]

Answer:

2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.

natta225 [31]

Answer:

25,800

Step-by-step explanation:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

75,200 - 49, 400 = 25,800

Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....
Annette [7]

Answer:

T_n =  -48* (-\frac{1}{2})^{n}

Step-by-step explanation:

Given

24, -12, 6,...

Required

Write a formula

The above sequence shows a geometric sequence because:

r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2} -- common ratio

The equation is determined using:

T_n = ar^{n-1}

Where

a = 24

Substitute values for a and r

T_n = 24* (-\frac{1}{2})^{n-1}

Apply law of indices:

T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}

T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})

T_n = 24* (-\frac{1}{2})^{n} * 1*-2

T_n =  1*-2*24* (-\frac{1}{2})^{n}

T_n =  -48* (-\frac{1}{2})^{n}

<em>The above represents the explicit formula</em>

weeeeeb [17]

Answer:

x = -14

Step-by-step explanation:

\frac{x}{2} = -7

multiply 2 on both sides

the 2's cancel out on the fraction side, leaving x = -7(2)

multiply -7 and 2 to get -14

x = -14
