Answer:

(–1, 5) does NOT make y < 3x + 8 true.

Step-by-step explanation:

First, let's substitute the values into the inequality. It's the one way to see if the point (–1, 5) is in the range of y < 3x + 8

5 ≟ 3(–1) + 8

5 ≟ 8 – 3

5 = 5 ✘

This means (–1, 5) does NOT make the inequality y < 3x + 8 true.

A cable TV company charges a flat fee of $25 for basic cable service, plus

vovangra [49]

Answer:

Step-by-step explanation:

Each movie costs $4 since the bill increased by $4 when the customer watched a movie.

$29 - $25 = $4

Create an equality using this information. Solve for x.

25 + 4x > 60

(25 + 4x) - 25 > (60) - 25

4x > 35

(4x)/4 > (35)/4

x > 8.75

Since the bill must stay under $60, round the answer down. The customer can watch 8 movies with the given price range.

I think the correct answer from the choices listed above is the second option. Combining probabilities is a function of mutually exclusive events.
