Answer:
g(4) = 7 and f(g(4)) = 43
Step-by-step explanation:
First find g:
g(x) = 3x-5
g(x) = 3(4) - 5
g(x) = 12 - 5
g(x) = 7
Plug in:
f(g(4))
f(7)
Now, find f:
7^2 - 7 + 1
49 - 7 + 1
42 + 1
f(x) = 43
Answer:
convert 2/5 to a decimal, which is 0.4
multiplying a value by 10 means you should move the decimal point one unit to the right
so 10 x 2/5 = 4
Step-by-step explanation:
Order of operations
PEMDAS
There are no parenthesis
There are no exponents
Now, we do multiplication and division from left to right
(9x9) + 8 - (8/10)
=
81 + 8 - 0.8
Now, we do addition and subtraction from left to right
(81 + 8) - 0.8
89 - 0.8
=
88.2
Answer:
-5/6
Step-by-step explanation:
3(1/6+2/9)+(-2)
3(7/18)+(-2) working what is in parenthesis.
7/6-2 reduced the numbers ( 3 and 18) with greatest common divisor . which is 3
-5/6 calculate the difference
