Answer:
y=3x
Step-by-step explanation:
y=3x is the one according to values in the table
You need to isolate/get x by itself in the inequality:
x - 10 < 6 - 5x Add 5x on both sides
x + 5x - 10 < 6 - 5x + 5x
6x - 10 < 6 Add 10 on both sides
6x - 10 + 10 < 6 + 10
6x < 16 Divide 6 on both sides to get x by itself
Simplify the fraction
So the 1st option
Answer:
A
Step-by-step explanation:
Answer:
cos6x.
Step-by-step explanation:
We use the identity
cosAcosB - sinAsinB = cos(A+B)
so cos5xcosx - sin5xsinx = cos(5x + x)
= cos6x.
