Answer:

  1/16

Step-by-step explanation:

Of the 16 ways you can answer the 4 questions, only one of those ways has all answers correct.

Each question can be answered 2 ways, and the answer to each one is independent of the answer to any other. So, there are 2·2·2·2 = 2^4 = 16 ways to answer the 4 questions.

asambeis [7]
H(x) = x - 7
g(x) = x^2
(g * h)(x) = x^2 (x - 7)
(g * h)(5) = 5^2 (5 - 7)

WILL MARK BRAINLIEST!
Vinvika [58]

<u>Using y = mx + b</u>

8y = 4x - 16  ⇒   y = \frac{1}{2}x - 2

-x = -2y - 4  ⇒  2y - x = - 4   ⇒   2y = x - 4   ⇒   y = \frac{1}{2}x - 2

Since the equations have the same slope (\frac{1}{2}x) and y-intercepts (-2), then they are the same line.  Thus, they intersect at every point so have infinite solutions.

Answer: A
