The number of students that earn straight A's decreases by half
each year. Currently there are 20 students who have all A's. Write
an equation to represent this scenario.

Answers

Answer 1

Step-by-step explanation:

20 ÷ 2 = S

S represents the students that have straight A's the next year. You would simply divide the current number of students by 2 and it will give you half the student number you had before. And those are the students who still are getting straight A's.

shift the graph of y=x down 2 units

Answers

Answer:

shown in drawing attached

y=x-2

Step-by-step explanation:

Shift each point down by two. First plot y=x, then shift down by 2 for each point.

please give thanks :)

You have to subtract 2 from the y-coordinate to shift the graph of y = x down to 2 units.

What is a transformation?

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

To shift the graph of y = x down 2 units, you can subtract 2 from the y-coordinate of each point on the graph.

This will be done by replacing y with y-2 in the equation, so the new equation would be y = x + (-2) which is y = x - 2

So the new equation for the graph will be y = x - 2

This will cause the graph to move down 2 units along the y-axis.

what conclusions can you draw about the roots of the equation x^3+x^2-2x+12=0​

Answers

Answer:

x=-3

Step-by-step explanation:

If x=-3, then

x³+x²-2x+12=-27+9+6+12=-27+27=0

If this is true, then x+3 is a factor. So:

x³+x²-2x+12/x+3=x²-2x+4

So the factors of x³+x²-2x+12 are:

(x+3)(x²-2x+4)

((x²-2x+4) has no real roots)........

Step 2: Rewrite

What are the coordinates of the image of vertex G after a reflection across the line y = x?​

Answers

Answer:

The coordinates of the image of vertex G are (-5, 4)

Step-by-step explanation:

Let us revise some cases of reflection

If the point (x, y) reflected across the x-axis , then its image is (x, -y) If the point (x, y) reflected across the y-axis , then its image is (-x, y) If the point (x, y) reflected across the line y = x , then its image is (y, x) If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)

From the given figure

∵ The line of the reflection is y = x

→ That means we will switch the coordinates of the point to find its image

∵ The coordinates of vertex G are (4, -5)

∴ The x-coordinate = 4 and the y-coordinate = -5

→ Switch the two coordinates

∴ The coordinates of its image G' are (-5, 4)

∴ The coordinates of the image of vertex G are (-5, 4)
