What is the rule? Then i will know how to it
Answer:
57 degrees
Step-by-step explanation:
Total measurement of any triangle is 180 degrees.
/_V=180-53.8-69.2=57 degrees
What you are given is f(x)=4x-8. When it says f(16)-f(0), it is telling you what the values of x should be equal to when placed into the given function. Whenever you see an x in your given function, it should be replaced with the number in parentheses after x. In this case, what you want to know is x=16 and x=0 since these are the numbers following f.
To get to your answer of 64, start out by setting up your equations.
Your first would be 4(16)-8 (since you’re filling 16 in for x).
Your next would be 4(0)-8 (since you’re filling 0 in for x).
Then you want to subtract these 2 equations from one another, as that’s what it’s asking for in the problem AKA f(16)-f(0).
4•16=64. 64-8= 56.
4•0=0. 0-8= -8.
56-(-8)= 64 since 2 negatives equal a positive.

For this you need to subtract 3 4\5 and 3 1\2. To solve these problems I personally used common denominators. Find least common factor which is 1. Think 1 times what is 5 the answer is 5. Now think 1 times 2 is what, the answer is 2. Now the common denominator will still be 2. Now do 5 time your numerator which is 20 which makes 20\1 and 2 time 1 which is 2 which make 2 over 1. So 20\1 minus 2\1 is 18\1. Then 3 minus 3. SO THE FINAL ANSWER IS 18\1.
