Answer: 1, 3, and 4 can form triangles. The rest can not.
Step-by-step explanation:
on triangles 1, 3, and 4, the 2 smaller sides added together are greater than the longer side.
For this case we must find a linear equation of the form:

Where,
m: slope of the line
b: cutting point with vertical axis.
For the slope we have the following equation:

Substituting values we have:

We observe that the slope of the line is not defined.
Therefore, the line is vertical.
Thus, the equation of the line is given by:

Answer:
The equation of the line is given by:

Answer:
<em>29 minutes more</em>
Step-by-step explanation:
Let m represent minutes
changing the statement to algebra, since the second company charges a different rate at night and weekend we have the equation below;
$19.99 + $0.35m > $29.99
Subtract 19.99 from both sides to isolate m and we have;
$19.99 -$19.99 + $0.35 > $29.99 - $19.99
= $0,35m > $10.00
Divide both side by 0.35 to obtain the value of m;
> 
= m > 28.57
<em>m ⩾ 29 minutes</em>
<em>The second company's will be twenty nine minutes or more costlier than the first company</em>
Answer:
The answer is 56 and that is no guess
