Answer:
The system of equations has infinite solutions. True for all y and x.
Given equations:
x + 4y = 0
20y = - 5x
Make x the subject for equation 1:
x + 4y = 0
x = -4y
Plug x as -4y in second equation:
20y = - 5x
20y = - 5(-4y)
20y = 20y
0 = 0
L.H.S = R.H.S
True for all y.
Therefore true for all x.
Answer:
5/12
Step-by-step explanation:
The probability of rolling an odd number is 3/6, which is 1/2
The probability of rolling a factor of 12 is 5/6 (1,2,3,4,6)
1/2 x 5/6 = 5/12
After making six monthly payments on her car loan, Thomas's savings account will be lower.
Answer:
12/20
Step-by-step explanation:
Cos is adjacent over hypotenuse
Sin is opposite over hypotenuse
Tan is opposite over adjacent
In this case, we have cosine so we would take the adjacent (12) over the hypotenuse (20), and that will be used to find the answer
