The work of a student to solve the equation 2(4x - 4) = 8 + 4x + 4 is shown
below:
Step 1. 2(4x - 4) = 8 + 4x + 4
Step 2. 6x - 6 = 12 + 4x
Step 3. 6x - 4x = 12 + 6
Step 4.2x = 18
Step 5. x = 9
In which step did the student first make an error and what is the correct step?
(1 point)
Step 2, 8x - 6 = 2(6 + 2x + 2)
Step 2, 8x - 8 = 12 + 4x
Step 3, 6x - 4x = 12 - 6
Step 3, 6x + 4x = 12 + 6

Frontal lobe: The part of each hemisphere of the brain located behind the forehead that serves to regulate and mediate the higher intellectual functions. The frontal lobes are important for controlling thoughts, reasoning, and behaviors.

the lobe of the brain located closest to the ear. Structures in the temporal lobe are important for memory, language, and hearing, along with many other functions.

The primary visual cortex is located here and thus the occipital lobe is considered the visual center of the brain.

The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area in the skull. It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature.

Answer:

y = - x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 0) ← 2 points on the line

m = [tex]\frac{0-6}{6-0}[/tex] = [tex]\frac{-6}{6}[/tex] = - 1

The line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - x + 6 ← equation of line

On July first there were twice as many overdue books as there had been on May first, although a record number of books had been returned during the interim.Which of the following, if true, most helps to explain the apparent inconsistency in the results of the librarys policy?(A) The librarians did not keep accurate records of how many children took advantage of the grace period, and some of the children returning overdue books did not return all of their overdue books.(B) Although the grace period enticed some children to return all of their overdue books, it did not convince all of the children with overdue books to return all of their books.(C) The bookmarks became popular among the children, so in order to collect the bookmarks, many children borrowed many more books than they usually did and kept them past their due date.(D) The children were allowed to borrow a maximum of five books for a two-week period, and hence each child could keep a maximum of fifteen books beyond their due date within a two-month period.(E) Although the library forgave overdue fines during the grace period, the amount previously charged the children was minimal; hence, the forgiveness of the fines did not provide enough incentive for them to return their overdue books.
