Answer:
y = - 
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 7 when x = - 4, then
7 = 
( multiply both sides by - 4 )
- 28 = k
y = 
← equation of variation
When x = 5 , then
y = 
= -
Answer:
Press the png
Step-by-step explanation:
Let x and y represent the two angles.
.. x + y = 90 . . . . . . two angles are complementary
.. x -2y = 15 . . . . . . one angle is 15 more than twice the other (y = smaller angle)
Subtract the second equation from the first.
.. (x +y) -(x -2y) = (90) -(15)
.. 3y = 75
.. y = 25
The smaller angle is 25 degrees.
