Mathematics

Answer:

Step-by-step explanation:

I am very sorry if this doesnt make sense but i tried to give you an example for the first one so you could figure out the 4 and 5.

If y=12 when x=6, determine y when x=18.

Ok if y=12 and x=6 they add up to 18. So X=6 then you are going to have to times 6 by three to get x to equal 18. That means we have to times y by 3 also which equals 36. We can check this by making sure they are congruent or the same. So if the origanal question said y equals 12 and x equals 6. How do you make sure it's the right answer? What do they have in commmon? Well to get 12 you have to multiply 6 by 2 to get 12. And to get 6 you have to divide 12 by 2. So the common number is 2. So for x to equal 18 we have to figure out is the have something in common, so 18 times 3 equals 36 and if 36 divided by 3  we get 18. So the common number is 3.

Which of the following points lies in the solution set of the inequality y &gt; 3x +10?
shepuryov [24]

Since 3 is greater than -3, hence (-1, 3) lie in the solution set. Option C is correct

In order to determine the points that lie in the solution set of the inequality y > 3x +10, we will substitute the x-coordinate and see if <u>y is greater than the result.</u>

<u />

For the coordinate point (1, 10)

y > 3(1) +10

y > 13

Since 10 is not greater than 13, hence (1,10) does not lie in the solution set.

For the coordinate point (4, 20)

y > 3(4) +10

y > 22

Since 20 is not greater than 22, hence (4,20) does not lie in the solution set.

For the coordinate point (-1, 3)

y > 3(-1) +10

y > -7

Since 3 is greater than -3, hence (-1, 3) lie in the solution set.
