Answer:22
Step-by-step explanation: since f(8) so x=8
substitiuting x in 2x+6
f(8)= 2x8+6=22
so f(8)=22
Hope this helps! :)
Step-by-step explanation:
A is the answer to the question
Answer:
3.25
Step-by-step explanation:
2 + d = 2 - 3 (d - 5) -2
d= -3d+15-2
4d=13
d= 13/4= 3.25
Answer:
c.k¹¹
Step-by-step explanation:
Anything raised to the power of 0 is one so k^0=1
k^4k^7
Since they have the same base you can just add them
4+7=11
Answer:
Step-by-step explanation:
Given that
-3a+6b=a+4b
We want to make b subject of formula
First to remove the 4b in the Right hand side of the equation
Subtract 4b from both side of the equation
-3a+6b-4b=a+4b-4b
Then we have,
-3a+2b=a
Now to remove the -3a from the left hand side of the equation add 3a to both side
Then,
-3a+2b+3a=a+3a
2b-3a+3a=4a
Then, 2b=4a
Divide both side by 2
2b/2=4a/2
b=2a.
