-2x-6<=1
insert values of x as -1, -2, -3, -4
-4 does not work
I don't have a crush so, I'll just take the 5 points :)
Answer:
x=-19
y=55
Step-by-step explanation:
y=-3x-2.
5x+2y=15
substitute y into 5x+2y =15
5x +2 (-3x-2) = 15
distribute
5x -6x-4 = 15
combine like terms
-x-4 =15
add 4 to each side
-x-4+4 = 15+4
-x=19
multiply by -1
x = -19
now lets find y
y= -3x-2
y = -3(-19) -2
y = 57-2
y =55
Well to isolate the variable you should subtract 6 from both sides resulting in -4y > 16
Now just divide by -4, however, keep in mind that when you divide or multiply by a negative number when there is a sign, always switch the sign, so just divide by -4 and get y < 4
Answer:
The probability of selecting two democrats is 1/380
Step-by-step explanation:
- Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
- Probability of an event = Number of favourable outcomes / Total number of outcomes.
Here we are given the people as,
8 democrats, 8 republicans and 6 independent.
So total number of people are: 8+6+6=20
Probability of choosing first democrat = 1/20
Probability of choosing first democrat = 1/19
Thus P( two democrats in succession ) = 1/20 ×1/19
= 1/380
