Answer: B
Step-by-step explanation:
YOU MINUS 4 -4 WHICH IS -8 SO ITS B
Answer:
The answer is -1/2
Step-by-step explanation:
We first start by removing x in order isolate the y variable
2y = 6 - x
y = 
Further, we simplify the equation in order to get the value of m (slope)
y = 3 + 
Therefore, our slope is equivalent to -1/2
9514 1404 393
Answer:
Step-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.
Just be patient: y = -sqrt(8.41) = calculator (negative value) and so on. The last one is 0! :)
