Answer:
b. infinite solutions
Step-by-step explanation:
Therefore, the graphs are the same.
If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
= (1 - tan^2 (x)) / (1 + tan^2 (x))
= (1 - (-4/3)^2) / (1 + (-4/3)^2)
= (1 - (16/9)) / (1 + (16/9))
= (9 - 16) / (9 + 16) [By multiplying numerator and denominator with 9]
= (-7) / (25)
= -7/25
Answer:
-60.75
Step-by-step explanation:
-12 / 8 = -3/2
18 / -12 = -3/2
-27 / 18 = -3/2
This is a geometric sequence with a common ratio of -3/2.
an = 8 (-3/2)^(n-1)
The sixth term is:
a₆ = 8 (-3/2)^(6-1)
a₆ = 8 (-3/2)^5
a₆ = -60.75
The answer is B. -6p-78. Pls mark brainliest.
Answer: 27/14
Step-by-step explanation:
(x+2)/x +(x-6)/3x = (2x+9)/5x
(3x+6)/3x + (x-6)/3x = (2x+9)/5x First term: [(x+2)/x]*(3/3) = (3x+6)/3x
(4x)/3x = (2x+9)/5x Combine (3x+6)/3x + (x-6)/3x [=(4x)/3x]
(4/3)*5x = 2x + 9 [(4x)/3x = 4/3] and multiply both sides by 5x
(20/3)x - 9 = 2x [(4/3)*5x] = (20/3)x; Subtract 9 from both sides
20x - 27 = 6x Multiply both sides by 3
14x = 27 Simplify
x = 27/14 And solve
