2. Graph the solution set to the following inequality: 7-y<2x

nirvana33 [79]

Step-by-step explanation:

First solve for y,

7-y<2x

7-2x<y

y>-2x+7

your y intercept would be (0,7)

and your slope would be -2/1 so, you go down 2 and 1 to the right.

Since this is a greater than symbol, we have to shade above the line and the line would also be a dotted line.

List the members of P(fa, b, c, d}). Which are proper subsets of fa, b,c, d)?

ankoles [38]

Answer: As i understand, the set is P = {a,b,c,d}

then all the proper subsets are all the sets that belongs to P, that are different of P. Then A is a subset of P if all the elements of A belongs to P, but A is not equal to P

this is:

the sets of one element : {a}, {b}, {c}, {d} and the null set; ∅

sets of two elements: {a,b} , {a,c} , {a.d}, {b,c}, {b,d}, {c,d}

sets of three elements : {a,b,c}, {a,b,d}, {a,c,d}, {b,c,d}

and there arent sets of 4 elements or more.

The average of 8 numbers is 10. the average of 6 of the numbers is 12 what is the average of the other 2 numbers

omeli [17]

So, all 8 numbers added up would equal 80. and all 6 numbers added up would equal 72. The subtract them. 80-72 is 8. Then divide by 2 because there are 2 numbers. 8/2 is 4. (4 is your answer)
