start with slope-intercept form:

-9-11/1+3 = -20/4 = -5

your slope is -5

next, do point-slope form:

y+9 = -5(x-1)

y+9 = -5x+5

 -9         -9

How in the world do I do this can somebody help please.
ValentinkaMS [17]

Answer:

Bl^2+4Bl*Fh

Step-by-step explanation:

I'm not quite certain what "draw a net" means here. But for part b, we are doing the formula. The bottom part is a square(assumingly so take this with a grain of salt), thus making the base equal to 3*3 cm or 9 cm^2. The triangular faces are each 3*2.24 cm or 6.72 cm^2. We then multiply this by 4 to get 26.88. Thus, the equation is Bl^2(Base length squared)+Bl*Fh(Face height, I forgot the official name sorry about that)*4 for part b.

The manager at Gabriel's Furniture Store is trying to figure out how much to charge for a bookshelf that just arrived. The books
melomori [17]

First: markup rate × wholesale price = amount of markup

Second: Well the markup rate is a percentage, you have to convert it into a decimal. Percent means "out of one hundred," so <span>80%</span> is equivalent to <span>80/100 </span>which is also equal to <span>80÷100</span>.

<span>Third: 80÷100=0.80</span>

0.80 × $93.00 = $74.40

Fourth: The markup rate is a percentage of the wholesale price that is added to get the retail price, you can find the retail price with the following equation: amount of markup + wholesale price = retail price

<span>$74.40</span> + <span>$93.00</span> = <span>$167.40</span>

The retail price of the chair should be <span>$167.40</span>.

Find the slope and the equation please<br><br>and step by step PLEASE.​
Svetllana [295]

Answer:

y = \frac{-4}{5}x + 1

Step-by-step explanation:

Slope is rise over run, or the vertical progression over the horizontal progression.

Your example has a line that heads downwards, so we know that the slope is negative. If we count the squares, the "rise" is down by 4. We count the squares going horizontally and there are 5. So, your slope is \frac{-4}{5}.

The other half of the equation is the y-intercept, or where the line crosses the y axis. It appears to be at (0 , 1), so we can say that your y-intercept is 1.
