Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
First, do parenthesis.
4(2+3)
Add.
3+2=5
Multiply.
4*5=20
Rewrite the equation problem.
x+20<5x
Secondly, subtract 20 from both sides.
x+20-20<5x-20
Solve.
x<5x-20
Thirdly, subtract 5x from both sides.
x-5x<5x-20-5x
Solve.
5-1=4
-4x<-20
Then, multiply -1 from both sides.
(-4x)(-1)>(-20)(-1)
Solve.
(-4x)(-1)=4x
(-20)(-1)=20
4x>20
Divide by 4 from both sides.
4x/4>20/4
Solve.
20/4=5
x>5
The solutions is 5, therefore, the correct answer is x>5.
Answer:
f(8) = 6
Step-by-step explanation:
Just plug in x=8
f(x) = 2(x - 5)
f(8) = 2(8 - 5)
f(8) = 2(3)
f(8) = 6
