____
in which:

Parentheses are the first priority; if they occur.

then:
Exponents are the second priority if they occur.

followed by:
Multiplication and
Division;  if any of these occur; and the priority is from the left-hand side to the right-hand side—if they occur.  So; multiplication does not necessarily take priority over division.  Rather, "Multiplication and Division" are treated equally, as the "next priority", from "left to right"—as they occur/if they occur;

followed by:

Addition and
Subtraction; of any of these occur; and the priority is from the 'left-hand side to the right-hand side—if they occur.  So; addition does not necessarily take priority over subtraction.  Rather, "Addition and Subtraction" are treated equally, as the "next priority", from "left to right"—as they occur/if they occur.
____

So:  For our given problem; we can solve:

  " 8(6 + 4) " ;  which is the same as:
                " 8 * (6 + 4)  ";

 We have a "multiplication" and a "parentheses" ;
    So:  The "parentheses" take first priority:
____

     "(6 + 4) = 10 " ;

now:  " 8 * (6 + 4) " ;

            =    8 * 10 = 80 ; which is our answer:
____
Alternate method:
Note the distributive property of multiplication:
          →   a(b + c) = ab + ac  ;

So:   8 (6 + 4) = (8*6) + (8*4) ;

                      =    48 + 32;

                      =    80 ;  which is our correct answer!

Answer:

rental cost of each movie is $2.5

rental cost of each video game is $5.5

Step-by-step explanation:

use x for movie and y for video game. Then you get the equations
2x+12y=71 and 5x+3y=29

then you solve each equation for either x or y.
when you solve for y you will get
y = (71 -2x) / 12    and y = (29 -5x) / 3

because y is the same, you put those equations together
(71-2x) / 12 = (29 -5x) / 3
then solve for x and you get x = 2.5

then you put 2.5 for x in either of the original equations and solve for y.
for both equations you will get y = 5.5

The test that does not include scales for assessing test taker response biases and faking is D. Meyers-Briggs Type Indicator.

A popular objective personality measure is the Millon Clinical Multiaxial Inventory—Third Edition (MCMI-III). The MCMI-III assesses the presence of psychological disorders, including personality disorders.

The MMPI-2 is a 567-item true/false self-report questionnaire that assesses a person's psychological state. It includes nine validity scales (or 'lie' scales) that assess lying, defensiveness, faking good, and faking bad, among other things.

The MMPI-2-RF provides accurate measurement of 40 dimensional constructs related to personality and psychopathology in the context of the new paradigm (with an additional nine scales measuring protocol validity, or the individual's test-taking approach).

The Myers-Briggs Type Indicator is an introspective self-report questionnaire used in personality typology to identify different psychological preferences in how people perceive the world and make decisions. Introversion/extraversion, sensing/intuition, thinking/feeling, and judging/perceiving are the four categories. Unlike others, this first use a scale.

The equation of the line y = -x/2 + 6, with slope -1/2,

What is equation straight line?

Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

slope m = -1/2.

So the line can be formed by (y-y1) = m (x-x1)

(y-7) =  -1/2* (x+2)

y = -x/2 - 1+7

y = -x/2 + 6

Hence the equation of the line y = -x/2 + 6.

If the equation for a line "u" be represented as [y = (-2x + 10)], then the equation of line "v", being parallel to line "u" and passing through the point (-1, 2) will be [y = (-2x)].

As per the question statement, the equation for a line "u" can be represented as [y = (-2x + 10)],

And we are required to determine the equation of another line "v", which is  parallel to line "u" and passes through the point (-1, 2).

To solve this question, first we need to know about a property of parallel lines, which is, "Any straight line parallel to a line of known slope will also have the same slope"

Now, the formula to determine the equation of a straight line having a known slope, say "m" and a y-intercept of "c" goes as, [y = (mx + c)], also known as the slope-intercept form of line. Comparing the equation of line "u" with this slope-intercept form, we get, [m = (-2)] and [c = 10].

That is, the slope of line "u" is (-2), and hence, the slope of line "v" must also be (-2) since they are parallel to each other.

Also, the formula to determine the equation of a straight line having a known slope, say "m", and passing through a known point, say (x₁, y₁), goes as, [(y - y₁) = {m(x - x₁)],  and using [m = (-2)] and [(x₁, y₁) = ((-1, 2)] in this formula, we get,

[(y - 2) = (-2){x - (-1)}]

Or, [(y - 2) = (-2)(x + 1)]
Or, [(y - 2) = (-2x - 2)]

Or, [y = (-2x - 2 + 2)]

Or, [y = (-2x)]

That is,  the equation of line "v", being parallel to line "u" and passing through the point (-1, 2) will be [y = (-2x)]

Answer:

The correct answer is B. Vertical lines have an undefined slope.

The numbers replacing A, B and C in the polynomial equation  are -2, -2 and 2 respectively.

In the equation y = x² + 3x - 2,

When x = -3 ,

y = 9- 9- 2

 = -2 = A

So, A = -2

When x = 0 ,

y = 0+ 0- 2

 = -2 = B

So, B = -2

When x = 1 ,

y = 1 + 3 - 2

  =4 -2

  =2 = C

So, C = 2
