Answer:
y=4x-17
Step-by-step explanation: Distribute the 4(x-5)
4x-20
Then add three to both sides
y=4x-17
3.70 and 3.700 are some examples to get you started.
Answer:
P( sum is prime )= 73/216
Step-by-step explanation:
The minimum value of the sum will be 3 and maximum value will be 18. So the prime numbers in this range are 3 , 5, 7, 11, 13, 17.
P(sum=3)=1/216, P(sum=5)=6/216, P(sum=7)=15/216, P(sum=11)=27/216, P(sum=13)=21/216, P(sum=17)=3/216.
The final probability will be sum of the above given probabilities.
Hence P( sum is prime )= 73/216
Answer:
A=-4 B=-8 C=8
Step-by-step explanation:
If you need to check these answers multiply the answer by the second number.
A) -4x-3=12 A negative times a negative is always positive.
B)-8x9=-72 A negative times a positive is a negative.
C) 8x-2=-16 A negative times a positive is a negative.
