Which equation represents a line which is parallel to the line 7x - y = 4?

Answers

Answer:

Step-by-step explanation: step : Place the given line’s equation in slope- intercept form y = mx + b. A line parallel to this line will have the same slope.

7x - y = 4. Yields y = 7 x - 4. Therefore y = 7x - 5 is the correct answer.

PLEASE HELP if 5 more than 3 times a number is -4, what is the number?

Answers

Answer:

x = -3

hope it's helpful ❤❤❤

THANK YOU.

Hey there!

The answer to your question is "n = -3"

First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"

3n

Next, "5 more" represents addition, so "+ 5"

3n + 5

Finally, "is -4" means it is equal to -4, so "= -4"

3n + 5 = -4

Now that we have our equation, we can solve:

3n + 5 = -4

First, we subtract "5" from both sides of the equal sign:

3n = -9

Lastly, we divide both sides by "3".

n = -3
