Answer:
x ≤ 4
Step-by-step explanation:
6x + 3 ≤ 27 subtract 3 both sides
6x ≤ 24 divide 6 both sides
x ≤ 4 There's your answer
Answer:
Changing value of "d" changes the vertical shift of the cosine graph.
Step-by-step explanation:
Question says to find about how does your cosine graph change when including the d-value.
General equation of cosine function can be given as:

In that formula, value of "d" gives vertical shift.
So changing value of "d" changes the vertical shift of the cosine graph.
answer:
set 4
Step-by-step explanation:
because when you divide the numbers 12,16 and 20 by 2 you'll get 6,8 and 10 which is a Pythagoras family....and it will form a right angle triangle
