Hello from MrBillDoesMath!
Answer:
9 3/8
Discussion:
2 1/7 = 15/7
4 3/8 = 35/8
so the product
(2 1/7) * ( 4 3/8) =
15/7 * 35/8 =
15/7 * (7 * 5)/8 =
since 35 = 7*5. Cancel "7" in numerator\denominator to get
(15 * 5) / 8 =
75/8 =
9 3/8
Thank you,
MrB
C=.35x + 9.50
.35 is the amount per check so you put the x next to it because that represents how may check you use plus 9.50 per month
hope this helps
Answer:
maximum
vertex at (-1,1)
axis of symm: x = -1
2 solutions
(-2,0) and (0,0)
Step-by-step explanation:
Morse code is essentially the same as binary. That is, there are two "digits", a dot or a dash.
There are 26 letters in the English alphabet. Clearly, we can't just use one dot or dash, since that could only encode 2 letters at the most. We can't use two symbols because that could only encode 4 letters at the most. Similarly, 3 symbols means

letters at most.
We have to select the smallest power of 2 that exceeds or is equal to 26. In this case,

, so we would have to use up to 5 symbols to encode each letter in the alphabet.
Answer:
there are no solutions
Step-by-step explanation:
x-3y=-3
-2x+6y=12
multiply the first equation by 2
2( x-3y)=-3*2
2x-6y = -6
add the 2 equations together
2x-6y = -6
-2x+6y=12
-------------------
0 = -6
this is not true
so there are no solutions
