Answer: -17/28
Step-by-step explanation:
This is very easy.
We read f(x) as "a function of x"
Think of it as a machine. It takes in x, and gives us f(x) after doing some things to it.
f(x) = (x) × 4/7 + 9/4 ,
f(-5) = (-5) × 4/7 + 9/4
Let's work this out now!
= (-5) × 4/7 + 9/4
= -20/7 + 9/4
Now make into 1 fraction with common denominator
= -80/28 + 63/28
= -17/28
Translation- you subtract 4 from the given x-coordinate and subtract 11 from the given y-coordinate.
Answer:
10.68
Step-by-step explanation:
8.9*1.2
Well, 1 foot has 12 inches. Since there is 4 feet you multiply 12 by 4. Which is 48. Once you have 48 inches you add the extra 8 inches. So you get 56 inches
