Answer:
48 is 60% of 80
Step-by-step explanation:
set it up as an equation
(100) 48 = × 80 (100)
4800 = 80x (divide both sides by 80)
x=60
meaning that 48 is 60% of 80
Answer:
c. both
Step-by-step explanation:
Given equation is
Now we need to check if the graph of is symmetric with respect to which axis?
a. x-axis c. both b. y-axis d. neither
We know that if f(-x) reflect the graph about y-axis
so let's change x by -x into given function to see if that equation remains unchanged or not
That is same as previous equation.
<u>Hence given graph is symmetric about y-axis.</u>
We know that if -f(x) reflect the graph about x-axis
so let's change y by -y into given function to see if that equation remains unchanged or not
That is same as previous equation.
<u>Hence given graph is symmetric about x-axis.</u>
So the correct choice is c. both
