Answer:
No
Step-by-step explanation:
To obtain the inverse function
let y = f(x) and rearrange making x the subject, that is
y = 3x + 1 ( subtract 1 from both sides )
y - 1 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
Answer:
<em>m∠1 = 90°</em>
<em>m∠2 = 35°</em>
<em>m∠3 = 55°</em>
Step-by-step explanation:
Find the diagram attached
From the diagram:

Given that <4 = 35°

The sum of the angle on a straight line at point A is 180°. Hence:

The sum of angle in the triangle ABC is 180°, hence;
