There are 12 mo per year. So 4 years =48 mo. So at $415/mo x 48=$19,920.
All 3 angles have to add up to be 180 so the answer would be 90
The solutions are C = 2 and C = -2
We can find this by solving for C.
C^2 - 4 = 0 ----> add 4 to both sides
C^2 = 4 ----> Take the square root of both sides
C = 2
However, since we used the square root function, we have to include a negative form of the answer as well as the positive one we found.
Answer:y varies directly as x if y = kx for some constant, k. In other words, y/x is constant. y varies inversely as x if y = k/x for some constant, k.
Step-by-step explanation:
Answer:
D: {-4, -1, 4}
R: {0, 2}
Step-by-step explanation:
The domain of a relationship is the possible values of x. On the other hand, the range is the possible values of y. To write out the domain and range of a discrete relationship simply write the given x and y values. The x values are -4, -1, and 4. Set notation is written least to greatest and uses brackets, so the domain is {-4, -1, 4}. Do the same for the range and remember that numbers should not repeat in set notation. This gives you {0, 2}.
