Hi there!
We are given the equation 20 + 6c - 2c², and are told to factor it. Well, to do this, we can first rearrange the terms in decreasing order: -2c² + 6c + 20. Next, we see that we can take out a common factor -2 from the whole equation. This gives us -2(c² - 3c - 10). Now, we take the constant term, -10, and we find all it's factors.
-1 10
-10 1
-5 2
-2 5
Now, find the sums of the factors.
-1 + 10 = 9
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
We see that the only pair of factors that add up to -3 are -5 and 2. Now, we can factor the whole equation to -2(c + 2)(c - 5). Hope this helped!

(i’m not sure what to round it to)
subtract 192,300 from 203,400 to find the amount of change
(= 11,100)
then divide that amount from the original price (203,400)
then multiply that number by 100 to get a percent
finally round to a reasonable percent
Answer:
x-7 represents x moved 7 units to the left.
Step-by-step explanation:
The translation: (x, y) → (x - 7, y - 4) was performed on a triangle
x is translated into x-7. 7 is subtracted from x . It means x is moved 7 units to the left
y is translated into y-4. 4 is subtracted from y. It means y is moved 4 units down.
So x-7 represents x moved 7 units to the left.
31 and 15
31+15=46
31-15=16
Answer:
u can also get it on google like i did, dont cheat, etc. its not good
Step-by-step explanation:
Total Cost = (hourly rate)*(number of hours) + Fixed Initial Cost
y = 1.50x + 4
So the equation is y = 1.50x + 4
Plug in x = 12 to find y
y = 1.50x + 4
y = 1.50*12 + 4
y = 18 + 4
y = 22
It will cost $22 total to rent the bike for 12 hours.
