Answer:

  • B. (-1, 13) and (3, 5)

Step-by-step explanation:

<u>Solve by elimination:</u>

  • x² - 4x + 8 = -2x + 11
  • x² - 2x = 3
  • x² - 2x + 1 = 4
  • (x - 1)² = 2²
  • x - 1 = 2 ⇒ x = 3
  • x - 1 = -2 ⇒ x = -1

<u>Find values of y:</u>

  • y = -2(3) + 11 = 5
  • y = -2(-1) + 11 = 13

<u>The pairs are:</u>

  • (3, 5) and (-1, 13)

Correct choice is B

Solve the following exponential equations.<br> 2(4^x )+ 4^(x+1 )= 342
Cloud [144]

Answer:

  x ≈ 2.91644500708

Step-by-step explanation:

The equation can be simplified to ...

  2(4^x) +4(4^x) = 342

  6(4^x) = 342

  4^x = 57

Taking logarithms, we get ...

  x = log₄(57) = log(57)/log(4)

  x ≈ 2.91644500708
