Answer:
![x \cdot y=1](https://tex.z-dn.net/?f=x%20%5Ccdot%20y%3D1)
Step-by-step explanation:
![(7^x)^y = 7](https://tex.z-dn.net/?f=%287%5Ex%29%5Ey%20%3D%207)
Apply exponent rule
:
![\implies7^{xy}=7^1](https://tex.z-dn.net/?f=%5Cimplies7%5E%7Bxy%7D%3D7%5E1)
![\implies x \cdot y=1](https://tex.z-dn.net/?f=%5Cimplies%20x%20%5Ccdot%20y%3D1)
Possible values for x and y: ![x=\dfrac12 \ \ \ \ \ y=2](https://tex.z-dn.net/?f=x%3D%5Cdfrac12%20%5C%20%5C%20%5C%20%5C%20%5C%20%20y%3D2)
Answer:
C
Step-by-step explanation:
120° is an angle in the second quadrant.
The reference angle is the related acute angle in the first quadrant, that is
reference angle = 180° - 120° = 60° → C
Answer:y=3/7x+3 since 3 is the y intercept and you have to hit the positive 7 in the x intercept.
Step-by-step explanation:
Notice, the graph starts off with an account balance of $10, at the 10 over the y-axis, that means the initial amount in the account, or what he initially deposited was 10 bucks.
now... let's use any of the points, say hmm the 2, 10.44.
after 2 years, he's got an extra 44 cents in it, went up to 10.44.
bearing in mind that is a linear graph, and thus is a simple interest rate.
The answer is Angle.
Rays that share and endpoint form an angle. :)
