HELP with these two.

42d = -252 (since 42 is multiplied by d, you have to divide by 42 on both sides to get what d is)

d= -6

20 = n / (-4) (since n is being divided by -4, you have to multiply by -4 on both sides to get what n is)

n= -80

Step-by-step explanation:

to get what the variable is, you have to "undo" the operation that is being done.

your answer is b ^w^ hope i

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
