3 + 0.45*M<=8,40. Notice the equal, because you may use all the money. Then, rearranging: M<=(8.40-3)/0.45= 12, so M<=12. Now, obviously time is positive, so you may end saying 0<=M<=12, with M=0 meaning no call! :)
Answer:
3x² - 14x + 15
Step-by-step explanation:
Step 1: Write expression
(x - 3)(3x - 5)
Step 2: FOIL
3x² - 5x - 9x + 15
Step 3: Combine like terms
3x² - 14x + 15
Answer:
f(5)=38
Step-by-step explanation:
f(5) means x=5, or in this case, a=5. We plug in 5 as A. f(5)=7(5+1)-4. f(5)=7(6)-4.
f(5)=42-4
f(5)=38
Answer:
The two multiples are 42 and 48
6 times 7 is 42
and 6 times 8 is 48
I would say that the answer would be one thousandth because it is 3 decimal places behind the whole digit
