Assuming you meant to write
, then you can simplify this by first factoring the numerator and denominator.
Notice that (x+6) is common to the numerator and denominator. You can cancel this factor so long as you remember to exclude 6 from the domain.
Simplifying further, you have
, where x ≠ 6, x <span>≠ 7.</span>
Answer:What is the 11th term of this geometric sequence 5, 20, 80, 320? In the present GP, a = 5 and r = 20/5 = 4. So the 11th term of the GP = ar^10 = 5*4^10 = 5242880.
Step-by-step explanation:
Answer:
y = 70
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
y = 1/2(92+48)
y = 1/2(140)
y = 70
Answer:
697/168
Step-by-step explanation:
there goes your answer
4x - 7y = 7
3x - 9y = 7
3(4x - 7y = 7)
12x - 21y = 21
-4(3x - 9y = 7)
-12x + 36y = -28
12x - 21y = 21
-12x + 36y = -28
15y = -7
y = -7/15
4x - 7(-7/15) = 7
4x + 49/15 = 7
4x = 7 - 49/15
4x = 105/15 - 49/15
4x = 56/15
x = (56/15) / (4)
x = (56/15) * (1/4)
x = 56/60 or 14/15
So the solution is x = 14/15 and y = -7/15 or (14/15, -7/15)
Verify solution by plugging in x and y values and solving.
