graph A

no x-intercept

no y-intercept

H.A is y = 5

V. A. is x = 0

*****************************************

Answer: \frac{150}{31}

<u>Step by step explanation:</u>

log₆(5x + 6) - log₆(x - 4) = 2

log₆(\frac{5x+6}{x-4}) = 2

(\frac{5x+6}{x-4}) = 6²

(\frac{5x+6}{x-4}) = 36

5x + 6 = 36(x - 4)

5x + 6 = 36x - 144

       6 = 31x - 144

    150 = 31x

     \frac{150}{31} = x

**********************************************************

Answers:

  • a. (-1, -5)
  • b. up
  • c. x = -1
  • d. \frac{-2+\sqrt{15}}{3} and\frac{-2-\sqrt{15}}{3}
  • e. -2
  • f. see attachment
  • g. domain (-∞, ∞)  range [-5, ∞)

<u>Explanation:</u>

f(x) = 3x² + 6x - 2

      a=3  b=6 c=-2

x = \frac{-b}{2a} =\frac{-6}{2(3)} = \frac{-6}{6} = -1

Axis Of Symmetry: x = -1

f(-1) = 3(-1)² + 6(-1) - 2

       = 3 - 6 - 2

       = -5

Vertex: (-1, -5)

x = \frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

  = \frac{-6+/-\sqrt{6^{2}-4(3)(-2)}}{2(3)}

  = \frac{-6+/-\sqrt{36+24}}{6}

  = \frac{-6+/-\sqrt{60}}{6}

  = \frac{-6+/-2\sqrt{15}}{6}

  = \frac{-2+/-\sqrt{15}}{3}

x-intercepts: \frac{-2+/-\sqrt{15}}{3}

Toby has 75% as many comic books as Mitch. Jarrett has 25% more comic books than Mitch. If Toby has 45 comic books, how many com
RSB [31]

Answer:

Jarrett has 75 comics

Step-by-step explanation:

T = Number of comic books Toby has.

M = Number of comic books Mitch has.

J = Number of comic books Jarrett has.

Toby has 75% as many comic books as Mitch.

T = 3/4 * M

This is because 75% = 75/100 = 3/4

Jarrett has 25% more comic books than Mitch.

J = 5/4 * M

This is because 125% = 125/100 = 5/4

If Toby has 45 comic books, how many comic books does Jarrett have.

1) Substitute T = 45 and Solve for M

T = 3/4 * M

45 = 3/4 * M

45 ÷ 3/4 = M

45 * 4/3 = M

180/3 = M

M = 60

2) Substitute M = 60 and Solve for J

J = 5/4 * M

J = 5/4 * 60

J = 300/4

J = 75

Jarrett has 75 comics
