Answer:
Step-by-step explanation:
We are asked to find an integer x such that 
.
First of all, we will multiply both sides of inequality by 5.
Divide both sides by 
:
Therefore, the value of x is any number greater than 5.
Answer:
4(3 + 20)
Step-by-step explanation:
The largest GCF of 12 and 80 is 4. Factor out 4 to get your answer in distributive form.
Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
