Jen solved the equation 100 minus one-half x equals 92 to determine the number of questions, x, she answered incorrectly on a te

st. She began by subtracting 100 from both sides, then multiplying both sides by –2. Which best describes the accuracy of Jen’s work?
Incorrect. She needed to add 100 to both sides instead of subtracting 100.
Incorrect. She needed to multiply both sides by –2 first, then subtract 100.
Correct. She could have also subtracted 100 from both sides, then divided by Negative one-half.

Describe the pattern that you see in the table for the right column. Please help me describe it in complete sentences. Extra poi
Gwar [14]

The pattern on the table is x increases:

  • The sine of x increases
  • The cosine of x increases
  • The function sin²(x) + cos²(x) remains constant

<h3>How to describe the pattern?</h3>

The functions on the table of values are:

sin(x), cos(x) and sin²(x) + cos²(x)

To describe the pattern, we simply observe how the values of the function change, as x increases.

As x increases, on the table:

  • The sine of x increases
  • The cosine of x increases
  • The function sin²(x) + cos²(x) remains constant

Help! Due soon!!!!!!!!!
denis23 [38]

Answer:

78.75

Step-by-step explanation:

450 is increased by 75%

450 + 450*75%

Change to decimal form

450 +450*.75

450+337.5

787.5

Now decrease by 90%

787.5-787.5*90%

Change to decimal form

787.5-787.5*.9

787.5-708.75

78.75

Arrange the graphs in descending order (from highest to lowest) based on the values of their correlation coefficients.
Scrat [10]
Basically, the closer they fit to the imaginary line of best fit, the higher they are

the closer the dots are to the imaginary line, te higher the number

D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers

Which is a possible turning point for the continuous function f(x)?
babymother [125]

Answer:

We are given coordinates of a continuous function f(x)

(–2, 0)

(0, –2)

(2, –1)

(4, 0).

We need to find the possible turning point for the continuous function.

Note: Turning point is a point on the graph where slope of the curve changes from negative to positive or positive to negative.

A turning point is always lowest or highest point of the curve (where bump of the graph seen).

For the given coordinates we can see that  (–2, 0) and (4, 0) coordinates are in a same line, that is on the x-axis.

But the coordinate  (0, –2) is the lowest point on the graph.

Therefore, (0, –2) is the turning point for the continuous function given.

hoped this was helpful!
