Answer:
y = 2
Step-by-step explanation:
For the equation x - y = -1, if x = 1,
then we would plug that in to solve for the y value
1 - y = -1
Subtract 1 from both sides to find y
-y = - 2
Divide by -1 to find y
y = 2.
To double check our answer we would plug in our x-value and y-value into the equation
1 - 2 = -1
This is true, so our answer is y = 2

Answer:
-20
Step-by-step explanation:
absolute value of -3 is 3. 17 plus 3 is 20, and make it a negative
check: 17 + - 20 = - 3
Answer:
5 and 85 degrees
Step-by-step explanation:
Ok, so if 2 angles are complementary, that means when put together they equal 90 degrees.
So, let's say one angle is a.
This means the bigger angle would be 17 times the smaller angle, or 17a.
Now let's make an equation:
a + 17a = 90
Now, we have to combine the like terms:
18a = 90
Now in order to find the smaller angle, we just have to divide by 5:
a = 5
This means that the smaller angle is 5 degrees, but because the bigger angle is 17 times the size, we just multiply 5 and 17 together to get 85 degrees.
Hope this helps :)
