Answer:

1) 22

2)12

3)-80

4)-16

5)-10.5

6)-10

Step-by-step explanation:

-12x + 2y when x = -2 and y = -1

= -12 (-2) + 2 (-1)

= 24 + (-2)

= 22

10 + a - b when a = -4 and b = -6

= 10 + (-4) - (-6)

= 10 - 4 + 6

= 10 + 2

= 12

8(n-3) when n = -7

= 8 (- 7 - 3)

= - 56 - 24

= - 80

3 - x + 2(-x + 4) when x = 9

= 3 - 9 + 2 (- 9 + 4)

= - 6 - 18 + 8

= - 24 + 8

= - 16

12 - (15 + y) / 6 - 8 when y = -3

= 12 - 15 + 3 / 6 - 8

= 12 - 15 + 0.5 - 8

= - 3 - 7.5

= - 10.5

15 - a(-b) when a = 5 and b = -5

= 15 - 5 (5)

= 15 - 25

= - 10

If p→qp→q, and q→rq→r, then thats all it says
Angelina_Jolie [31]
Answer: then q→r

Explanation:

If p → q

and q →r , then  you can use the law of transitivity to conclude

q→r.

That is a basic law of sillogisms.

An example will help you to understand the transivity law:

Make p, stand for 3 > 3/4, q stand for 3/4 > 15 / 20, the you can conclude that 3 > 15 / 20.

3 > 3/4

3 /4 > 15 / 20

Then, 3 > 15 /20.

This is, from the fact that you know that 3 is gretar than 3/4 and that 3/4 is greater than 15/20, you can conclude that 3 > 15 / 20. That is transitivity and is a law of logic, which you can use to get conclusions.
