Answer:
2500 pence (C = 2500)
Step-by-step explanation:

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

Now multiply the substitutes with the co-efficient.
(10*150=1500 & 20*50=1000)
Add the addends
C = 2500
Answer:
15
Step-by-step explanation:
1st multiply the numbers: 25 × 9 = 225
2nd factor the number: 225 = √15^2
3rd apply radical rule: √15^2 = 15
Hope I helped :)
F(10) means they want you to plug in 10. The piecewise function tells you that when x is greater or equal to 3, you use 6-2x. What I am saying is that since the number you want to plug in is greater than 3, then you plug in 10 into 6-2x.
f(10)=6-2*10=-14
It might be c but I am not sure maybe ita wrong
The answer is 7/-6
