Answer:
5 and 13
Step-by-step explanation:
To evaluate (w ○ u)(8) , evaluate u(8) then substitute the value obtained into w(x) , that is
u(8) = = 8 + 9 = 17 , then
w(17) = = = 5
---------------------------------------
To evaluate (u ○ w )(8) , evaluate w(8) then substitute the value obtained into u(x) , that is
w(8) = = = 4 , then
u(4) = 4 + 9 = 13
Answer:
Substitute the value of 7 into the variable x. Then solve the equation.
f(7) = 10 - 2(7)
f(7) = 10 - 14
<h2><em><u>
f(7) = -4 is the answer.</u></em></h2>
6 3/7 multiplied by 21 is 135. Your answer is C. 135 <span />
