Yes, because when you multiply 440,000 times 10 you would get 4,400,000. The 4 represents where the 1 is at right now! Therefore, the answer is yes.
Answer:
1/3
Step-by-step explanation:
Gradient=3/9=1/3
Substitute the given into the function
f(-4) = |7(-4) - 3|
now solve
f(-4) = |-28 - 3|
f(-4) = | -31|
the absolute value of |-31| is 31
so,
f(-4) = 31
Hope this helps :)
