Answer:
y=-4x-5
Step-by-step explanation:
The slope of the line is - 4, the equation of line is y=-4x-5
Answer:
x =
y
Step-by-step explanation:
Given x : y = 2 : 3
Express the ratios as a fraction, that is
=
( cross- multiply )
3x = 2y ( divide both sides by 3 )
x =
y
Hi there! I can help you with these! For these types of questions, all you have to do is that if there is a markup, multiply by one hundred something to get the new price, because you're including the original price and the markup. For example, if there is a 75% markup on something, you multiply by 175% (1.75). Or, if there is a markdown, basically multiply by the remaining percentage. For example, if the markdown is 35%, you multiply the original price by 65% (0.65), because that is the amount of the price that it's on sale for. With that being said, if you do this correctly, here are the answers:
1. $54
2. $2.25
3. $90
Hopefully if you're talking about the markup or markdown from these prices, those are your answers.

Answer:
x = 6
Step-by-step explanation:
The equation to solve is:

We can convert it to exponential form and find the answer. Below we show log to exponential form formula:

Now, we convert the log to exponential:

We now solve for "x",

We know the base number of log cannot be negative, so we disregard x = -6 and take x = 6 as our answer
