Answer:

1.) Polynomials are added or subtracted by changing the signs (when needed) and adding/subtracting like terms

2.)161

3.)cz

Step-by-step explanation:

2.) 81^2-80^2

  (81+80)(81-80)

    161x1

      161

3.)ab/c + xy/z = abxy/cz thus, the common denominator is cz

Hope this helps, hope your call goes well :)

Identify the type of data (qualitative/quantitative) and the level of measurement for the following variable. Explain your choic
AleksAgata [21]

Answer:

Option  C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.              

Step-by-step explanation:

We are given the following in the question:

Variable: Final exam scores (from 0 to 100) for graduating high school seniors.

The following variable is a quantitative variable.

Quantitative variable:

  • Their values are expressed in numerical.
  • They are either measured or counted.
  • Descriptive terms are not used to describe them.
  • They can either be continuous or discrete.

Since final scores have numerical values and are counted, they are quantitative variables.

Option  C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.

Level of measurement:

A score of zero means no true existence for score. That is true zero exist.

Thus, it is ratio because difference between the values in data can be compared meaningful and they have a true zero.

Write the equation of the line that passes through (2,3) and (4, 1) in point-slope form. Use (2,3) for (x1, y1).
earnstyle [38]

Answer:

y-2 = -(x-2)

Step-by-step explanation:

To find the slope

m = (y2-y1)/(x2-x1)  where (x1,y1) and (x2,y2) are two points on the line

    = (1-3)/(4-2)

   =-2/2

   =-1

The point slope form is

y-y1 = m(x-x1)  wher m is the slope and (x1,y1) is a point on the line

y-3 = -1(x-2)

y-2 = -(x-2)
