F(x)=-4x-1 if you sub 3 into it you get 3(-4)-1 which is -13 and 2x+4=10
Answer:
x=5
Step-by-step explanation:
I just rounded up my answer but if this is not correct then it is a decimal of 4.7
Answer:
Option (2) is correct.
Step-by-step explanation:
Given expression 
We have to find an equivalence value to the expression.
<u> Radical rule</u>,
Also,
Consider the given expression,
Applying radical rule to 
Thus, the expression becomes,
Thus, option (2) is correct.
The statement third "Betty wrote an indirect proof using contradiction' and statement fourth "Ken wrote direct proof using deductive evidence" are correct.
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have Ken's statements are shown in the table:
Angle AOC = Angle BOD (given)
Angle AOB + Angle BOC = Angle BOC + Angle COD (angle addition postulate)
Angle AOB = ANgle COD (subtraction property of equality)
Ken wrote direct proof using deductive evidence.
As we can in betty's proof:
Betty wrote an indirect proof using contradiction.
Thus, the statement third "Betty wrote an indirect proof using contradiction' and statement fourth "Ken wrote direct proof using deductive evidence" are correct.
