Answer:

-4

Step-by-step explanation:

This looks like point-slope form, which I find personally hideous. Let's change it to slope-intercept form to ease my conscience. (remember that slope-intercept form is y=mx+b, where m=slope and b=y-intercept!)

y - 5 = -4(x-8)

y - 5 = -4x + 32

y = -4x + 37

It's in slope-intercept form now! And -4 looks to be our m.

So the slope is -4.

Perfect patios is building a rectangular deck for a customer. According to the customer's specifications ,the perimeter should b

Paul [167]

Answer:

The length and width of the deck will be 11 meters and 9 meters respectively.

Step-by-step explanation:

The length of the rectangular deck is $l$ meter and width is $w$ meter.

The perimeter of the deck should be 40 meters. So, the first equation will be...

$2(l+w)= 40\\ \\ \Rightarrow l+w = 20 ..................................(1)$

The difference between twice the length and twice the width should be 4 meters. So, the second equation will be....

$2l-2w= 4\\ \\ \Rightarrow l-w= 2 .................................(2)$

Adding equation (1) and (2), we will get.....

$(l+w)+(l-w)= 20+2\\ \\ 2l= 22\\ \\ l= \frac{22}{2}= 11$

Now plugging this $l=11$ into equation (1), we will get....

$11+w= 20\\ \\ \Rightarrow w=20-11= 9$

So, the length and width of the deck will be 11 meters and 9 meters respectively.

Area = length × width

Joseph: 12 × 9 = 108 feet
Alana: 25 × 7 = 175 feet

175 feet - 108 feet = 67 feet

Answer: Alana's garden is greater by 67 feet compared to Joseph's
