<h2>Answer:</h2>

The correct statement is: Option: C

C. The slope of the first equation is not graphed the right way.

<h2>Step-by-step explanation:</h2>

The piecewise function is given by:

f(x)=   3x+1   if  x<2

and      4     if  2≤x<5

  • This means that the graph of a function in the interval (-∞,2) is a line with a positive slope i.e. 3 and hence is a increasing line.

Also, there is a open circle at (2,7)

( since the inequality is strict i.e. x<2)

  • Also, there is a horizontal line i.e. y=4 in the interval [2,5)

       i.e. there is a open circle at (5,4).

But the graph which is plotted for x<2

The slope of a line is: 1/3 and not 3

( Slope is defined as the ratio of change in y to the change in x)

In triangle ABC, m∠ABC = (4x – 12)° and
VashaNatasha [74]

The value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .

<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , angles and vertices.

It is given that

m∠ABC = (4x – 12)°

m∠ACB = (2x + 26)°

Let m∠ACB = y degree

It is asked that if x =19 degree , is the triangle equilateral

m∠ABC = (4x – 12)° = 4 *19 -12 = 64 degree

As in an equilateral triangle , the angles are all equal and equal to 60 degree.

If the value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .
