Answer: -1
Step-by-step explanation:
First change tan(315) to:

Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?

Answer: Directly proportional.
Step-by-step explanation:
The increase of one variable which causes the other variable to increase points to a directly proportional relationship between the two variables. Similarly, the decrease of one variable will cause a decrease in the other variable.
One variable can also be the constant multiple of the other. This means that if one changes, the other one will change in PROPORTION to it.
Bought the same number of Guppies and only Hank bought 2 additional Platies. Thus, let’s subtract the total of Hank and Martha
=> 18.33 – 13. 95 = 4.38
Thus, Hank paid an additional of 4.34 for 2 platies. Let’s divide to get the price of platies
=> 4.34 / 2 = = 2.19 (price of platies each.)
Let’s solve for price of guppies
=> 13.95 – 4.34 = 9.61
=> 9.61 / 3 = 3.20 (Price of guppies each.)
