4y = 42 - 3y
First, add '3y' to both of the sides.
Second, add '4y + 3y' to get '7y'.
Third, divide both sides by '7'.
Fourth, how many times does 7 go into 42? 42 ÷ 7 = '6'.

Answer:
y = 6
For lines to be perpendicular they would need to have opposite slopes, so for a slope of -3/7 the slope of a perpendicular line would be 7/3
The correct answer is that the variable does have a binomial distribution; P(success)=0.5; the number of trials is 5.
This is binomial because it has a fixed number of trials, the trials are independent of each other, the probability of success is constant from trial to trial, and there are only 2 outcomes.
Since success is getting an even number, and there are 3 even numbers out of 6, P(success)=3/6=0.5.
There are 5 trials because you are rolling the cube 5 times.
Answer is:
y = -4
There is no slope, therefore it is a horizontal line parallel to the x-axis.
Answer: x=5
Step-by-step explanation:
5 x 5 = 25 - 7 = 18
so x=5
