A) One solution: 5x +2y = 0 . . . . (any line with a different slope)
b) Two solutions: not possible
c) No solutions: 5x -2y = 0 . . . . (any different line with the same slope)
d) Infinitely many solutions: 10x -4y = 6 . . . . (any other equation for the same line)
Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
It helps if you can draw a figure of the problem. Make sure you memorize the definition of each trig function
Answer:
That is an acute angle.
Step-by-step explanation:
None of the angles exceed 95 degrees.
Answer with Step-by-step explanation:

In this sequence,
1st term = 4
2nd term = 7
3rd term = 12
4th term = 19
10th term = 103

in this sequence,
1st term = 2
2nd term =8
3rd term = 18
4th term =32
10th term = 200
Answer:
14/15
Step-by-step explanation:
P(S or T) = P(S) + P(T) = 3/5 + 1/3
= 9/15 + 5/15 = 14/15
