Add 3.5 to both sides
the answer is 8.9
aka 8 9/10
So the function is f(x)=2x+1
For the inverse function just replace f(x) with y and solve for x.
y=2x+1
y-1=2x
x=y/2 -1/2
Now to get the same labels replace x with f(x) and y with x to get
f(x)=x/2 - 1/2
Answer: b) FALSE
<u>Step-by-step explanation:</u>
In order to show triangle congruency, you must be able to prove one of the following theorems:
SAS: Side-Angle-Side
SSS: Side-Side-Side
AAS: Angle -Angle-Side
ASA: Angle-Side-Angle
HL: Hypotenuse-Leg <em>(can only be used for right triangles)</em>
<em />
We are only given information about two of the sides being congruent but no information on the third side or any of the angles so we canNOT prove the triangles are congruent.
