Find the rate of change (Pls help!)​

Answer: 11.5

Step-by-step explanation:

It’s delta y over delta x so you would take any two combination of coordinates and subtract and divide. I used 57.50-23 over 5-2... this gets you 34.5 over 3. This is also equal to 11.5 :)

(x,y)
east is an increase in x
west is a decrease in x
north is an increase in y
south is a decrease in y

so
3 east (x+3)
1 block south (y-1)
6 blocks west (x-6)
5 blocks north (y+5)

so in total, x+3-6 and y-1+5
basically x-3 and y+4
minus 3 from  and add 4 to y
(1,-2)
(1-3,-2+4)
(-2,2) is the dropoff point

the ratio of the heights of two similar triangles is 6:5 if the perimeter of the larger triangle is 49.2 feet. find the perimite
Mademuasel [1]

Answer:

41 feet

Step-by-step explanation:

We apply the theorem below:

If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.

Let x be the perimeter of the smaller triangle

If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,

6:5=49.2:x

6/5=49.2/x

Cross multiplying

6x=49.2 X 5

6x=246

x=246/6=41

The perimeter of the smaller triangle is 41 feet

Plz Help I do not understand this
loris [4]

Hello,

So Y variable is what you would start with.


20 <= he'll start off with for a

40 <= what he'll start off with for b




And X variables would be the # of hours you're working.


10 <= meaning every hour worked is worth 10 dollars

5 <= meaning every hour worked will be paid 5 dollars



So let's just say for option a he works two hours

(Option A)

10 (2) + 20

20 + 20

= 40


(Option B)

5 (2) + 40

10 + 40

50



As for your equations

Y = 10x + 40


Y= 5x + 40
