Answer:

C. (5, -3)

Step-by-step explanation:

Rewrite the first equation.

Multiply the second equation by 3 and write it under the first equation.

4x + 3y = 11

3x - 3y = 24

Now add the equations.

7x        = 35

Divide both sides by 7.

x = 5

Substitute 5 for x in the original first equation:

4(5) + 3y = 11

20 + 3y = 11

3y = -9

y = -3

Solution: (5, -3)

Answer:

C. (5, -3)

Step-by-step explanation:

4x + 3y = 11

x - y = 8  (multiply by 3) --> 3x - 3y = 24


4x + 3y = 11

3x - 3y = 24

---------------------add

7x = 35

 x = 5


5 - y = 8

y = 5 - 8

y = -3

(5, -3)

I don’t understand how to do this problem and get all the other answers, if you can help me that would be great!
Alecsey [184]

Answer:

Step-by-step explanation:

You can’t just substitute 0 for θ. 0 is a constant, not a variable.

secθ = -13/5

cosθ = 1/secθ = -5/13

sin²θ = 1 - cos²θ = 144/169

sinθ = -12/13

cscθ = 1/sinθ = -13/12

tanθ = sinθ/cosθ = 12/5

cotθ = 1/tanθ = 5/12

How do you simplify 52/45
rewona [7]

Answer:

1 (7/45)

Step-by-step explanation:

you'll see how many 45 can go into 52. Only 1 45 can fit into 52 with some leftover.

so to find the left over numbers you'll subtract 45 from 52= 7

so 7/45 is left over

Negative nine is greater than or equal to the sum of two - fifths times a number and 9.
Bumek [7]

Answer:

W is either -22.5, or less than -22.5

Step-by-step explanation:

-9>=2/5 times w (I wasn't sure what you meant by "and" 9. Like 9w?)

W has to be a negative number, or else it would be greater than 9, which would make the equation wrong.

2/5 times -22 1/2=-9. So w can be -22 1/2 or -22.5

W can then be anything "lower" (on the left side) of -22.5.

W<-22.5
