Answer:
Step-by-step explanation:
Assuming this integral:
We can do this as the first step:
Now we can solve the integral and we got:
So then we see that the integral on this case converges amd the values is 1/12 on this case.
All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:
2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15
This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
3 times 2.5 times 1. 05
= 3 x 2.5 x 1. 05
= 7.875
round to nearest tenth = 7.9
Answer:
not 35
Step-by-step explanation:
it 18
Simplify 140/96 into 35/24 since they have the common factor 4. Then convert it to 1 whole and 11/24
