Answer:
x=1, y = -3
Step-by-step explanation:
2x -y=-11
6x + y = 3
Add the two equations together
2x -y=-11
6x + y = 3
--------------------
8x = 8
Divide by 8
8x/8 = 8/8
x= 1
Now find y
6x+y = 3
6(1) +y = 3
6+y =3
Subtract 6 from each side
6+y-6 = 3-6
y = -3

Answer:
35.54 degrees
Step-by-step explanation:
For A, we have the opposite side (5) and the adjacent side (7). We can use the inverse of tan and to tan⁻¹(5/7) to get 35.54
We use the inverse of tan because tanΘ=opposite/adjacent, and we want to find the angle. We multiply both sides by the inverse bc that's what we would do if it was a number, and then get tan⁻¹(5/7)
Hope this helps. Sorry if I added too much explaination
Answer:
k+15
Step-by-step explanation:
The word "increased" indicates that there will be addition and the word "product" indicates there will be multiplication. Since it's asking for the product of 5 and 3, we can solve by multiplying those two numbers to get 15. Our variable k will then add 15. So, the final answer we get is: k+15
