18k - 4k = -10 - 4k
18k - 4k + 4k = -10
18k = -10
k= (18/10) = (9/5) = 1.8
Answer:
7/8
Step-by-step explanation:
Answer:

Step-by-step explanation:
<h2>In the unit circle we have:</h2><h2>

</h2>
In the picture we see that x=1/3.
<h2>Using de equation of unit circle:</h2>

y is positive because y are in the first quadrant of the cartesian plane.
1) (f + g)(2) = 7 + 3 = 10 The answer is C
2) (f - g)(4) = 11 - 15 = -4 The answer is A
3) f(1) = 2(1) + 3 = 5 g(1) = 1² - 1 = 0 The answer is D
4) (f xg ) (1) = 7/3 The answer is B
Answer:
60
Step-by-step explanation:
Prime factors of 4 = 2 × 2
Prime factors of 10 = 2 × 5
Prime factors of 12 = 2 × 2 × 3
The maximum occurrence of 2 is twice
The maximum occurrence of 3 is once
The maximum occurrence of 5 is once
LCM = 2 × 2 × 3 × 5 = 60
