Answer:
5.74
Step-by-step explanation:
fx=5(x+4)-6
f(19)=5(19+4)-6
19f=5(23)-6
19f=115-6
19f=109
f=109÷19
f=5.74 or 19 14/19
Answer:
D
Step-by-step explanation:
this is a "strategic" guess
77-27= 50 so when you add both it add up to 77 ,
50 is the answer
Answer: 2a^5+5b
Step-by-step explanation:
This is actually pretty simple
The exponent with the same power can be subtracted so
4a^5-2a^5 is 2a^5 like 4x-2x which is equal to 2x
4b+b is equal to 5b
2a^5+5b is your answer
3y - 1 = 28
+ 1 + 1
----------------
3y = 29
---- ----
3 3
y= 9.66
