Find the missing number so that the equation has infinitely many solutions.
Alex17521 [72]

equation has infinitely many solutions has the same number on both sides of the equal sign

-3x -21 + x + 5 = -20x -16

-2x -16 = -20x -16

so either you have -18x on the left or +18x in the right

HELP FAST 100 POINTS 100 POINTS What is the value of the expression when a = 5, b = 4 , and c = 6?⁢ 4a2b−c 2 5 9 10
ohaa [14]

For this case we must find the value of the following expression:

4a ^ 2b-c

When:

a = 5\\b = 4\\c = 6

Substituting the given values we have:

4 (5) ^ 2 * 4-6 =\\4 (25) (4) -6=\\400-6 =\\394

Finally, the value of the expression is 394.

Answer:

The value of the expression is 394.

Which represent geometric sequences? Check all that apply.
Anon25 [30]

The sequence that represents a geometric sequence can be seen in the 1st option and the 4th option in the image attached.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a set of integers that follows a pattern in which the following term is determined by multiplying the previous one by a factor known as the common ratio (r).

\mathbf{a_n = a_{n-1}\times r} or \mathbf{a_n = a_{1}\times r^{n-1}}

\mathbf{a_2 = a_{2-1}\times r}

\mathbf{a_2 = a_{1}\times r}

\mathbf{ r= \dfrac{a_2}{a_1}}

From the options given, the options that have geometric sequences are:

  • 3/16, 3/8, 3/4, 3/2

r = (3/8)/(3/16) = (3/4)/(3/8) = 2  (proves that it is a geometric sequence)

  • 3, 9, 27, 81
  • r = 9/3 = 27/9 = 3 (proves that it is a geometric sequence)
