C=25
Thus, The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
I'm sorry that I'm not in calculus, but hopefully I can help.
Personally, I would choose: D.) x; in the second equation ;
because it has easier numbers to figure out, you'll get it eventually...
(4,2) is is the distance from these coordinates
2m-6=48
+6 +6
__________
2m= 42
÷2 ÷2
_________
m=21
m=21 is the answer
To find the price of the stock after 12 weeks, you would have to plug in 12 to x
That would make your equation: y = -0.91(12) + 103.47
Then, you solve:
-0.91(12) would be -10.12
Your equation will now look like this:
y = - 10.12 + 103.47
Then you add -10.12 to 103.47
-10.12 + 103.47 = 92.55
y = 92.55
After 12 weeks, the price of the stocks would be $92.55
