Answer:
When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.
Step-by-step explanation:
Answer:
-7x+6
Step-by-step explanation:
Use the distributive property.
Add the negative in front of each number in the parenthesis.
- (7x) -(-6)
Since 6 is negative, a negative multiplied by a negative is equal to a positive. Change the negative in front of the 6 into a positive.
-7x + 6
Check the picture below.
now, since we know what "f" is, let us use the CNT triangle with the small COR one.
Answer:
randomly choosing a marble from a bag, replacing it, and choosing again
rolling a number cube, rolling again, and trying to match the first roll
Explanation:
In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.
The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.
3/8
1/4 becomes 2/8 to be equal so he used up 2/8
3/8 + 2/8 = 5/8 + 1/8 = 6/8 + (insert birdhouse here) 8/8 / 1
3/8 - 2/8 = 1/8 - 1/8 = 0/8 + (insert birdhouse here) 2/8
