The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
Answer:
the answer is 9/ 15
Step-by-step explanation:
Sin y = p / h
= 9/ 15 (from y reference )
cos x =b/h = 9 / 15
as from x reference b= 9

Answer:
The measure of angle T is 135 degrees.
Step-by-step explanation:
Let's just say the measure of angles T and S are variables t and s.
So the equation would be...
t + s = 180
Since they are supplementary angles, they add up to 180.
Also, we know that t is 3 times s.
t = 3s
Now we can solve this system of equations.
Substitute 3s into t of the first equation.
3s + s = 180
4s = 180
s = 45
Then, since we know that the measure of angle t is 3 times the measure of angle s, we can just multiply 45 by 3 and find the measure of angle t.
45 * 3 = 135
t = 135
So the measure of angle t is 135.

An inequality to model this would be
7x + 8y ≥ 336.
We multiply the number of minutes running, x, by the number of calories burned each minute by running, 7. We multiply the number of minutes swimming, y, by the number of calories burned each minute by swimming, 8. Adding these together, it needs to be greater than or equal to 336, since she wants to burn at least that many calories.
Answer:
100 Rs 5 coins and 50 Rs 2 coins
Step-by-step explanation:
Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2 coins
Let x be the number of 5 coins
and y be the number of 2 coins
The number of Rs.5 coins are twice as many as Rs.2 coins
Replace x with 2y
So 100 Rs 5 coins and 50 Rs 2 coins
