The algebraic rule for a reflection over the x-axis is one for the following:
A. (x,y), -axis → (-x,y)
B. (x,y), -axis → 0,x)
C. (x,y), -axis → (x,- y)
D. (x,y)x-axis →(-x-y)

Answer:

x=√y+4 or x=−√y+4

Step-by-step explanation:

Step 1: Add 4 to both sides.

x2−4+4=y+4

x2=y+4

Step 2: Take square root.

x=√y+4 or x=−√y+4

Answer: A

Step-by-step explanation: all answer choices have the negative sign for the x-value

Answer:

Correct answer: Choice a.

Step-by-step explanation:

Reflections In The Coordinate Plane

Reflect over the x-axis:

When we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the x-axis is the point (x,-y).

Reflect over the y-axis:

When reflecting a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the y-axis is the point (-x,y).

Note that the original triangle drawn by Jack and the image triangle have the same y-coordinate, but the inverse of the x-coordinate. This matches the definition of a reflection over the y-axis.

Correct answer: Choice a.

Answer:

755

Step-by-step explanation:

First do 180x7 which will give you 1,260 then do 1,260-375-137 which gives you 755.

Kate has the $748 of money.

Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.

Given:

Over the summer,

Kate earned $180 each week for 7 weeks.

That means,

she earns = 180 x 7

= $1260

She spends,

= 375 + 137

= $512

Now, she has the money = $1260 - $512

= $748

Therefore, she has the money $748.

hope it's right

Step-by-step explanation:

FOR X:

Let's solve your equation step-by-step.

4x+3=31

Step 1: Subtract 3 from both sides.

4x+3−3=31−3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

x=7

FOR Y:

Step 1: Simplify both sides of the equation.

(3)(7)+6y=30

21+6y=30

6y+21=30

Step 2: Subtract 21 from both sides.

6y+21−21=30−21

6y=9

Step 3: Divide both sides by 6.

6y/6=9/6

y=3/2

Since the corresponding sides of similar triangles are proportional,

Step-by-step explanation:

The trick here is finding the scale used in the plotting. From the question, we can find two hints;

- Number of cat = 40. Since it has an equal scale for both men and women. It means the 40 / 2 = 20 (20 men and 20 women) has cat as their favorite pet.

- Since we know that the number of men is 20, we have to find what individual box represents. There are 4 boxes, this means each box would have  a value of 20 / 4 = 5

Dog

For men, there are basically 5 lines (or boxes, if you prefer). This means 5 * 5 = 25

For women, there are basically 6 lines (or boxes, if you prefer). This means 6 * 5 = 30

Total frequency = 30 + 25 = 55

Hamster

For men, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

For women, there is basically 1 line (or box, if you prefer). This means 1 * 5 = 5

Total frequency = 15 + 5 = 20

Other

For men, there are basically 2 lines (or boxes, if you prefer). This means 2 * 5 = 10

For women, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

Total frequency = 10 + 15 = 25

Answer:

B

Step-by-step explanation:

From the given information:

Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.

This implies that:

8x + 3(1) = 8x + 3

Also,

If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;

i.e.

6(x) + 4(1) = 6x + 4

So;

the model that can determine when Sienna will have the same amount as Jacob is:

8x + 3 = 6x + 4

Answer:

-4 is the slope

Step-by-step explanation:

Because the line is going downwards that makes it a negative and if you count the boxes rise over run. You look for the point where the line meets a box perfectly and then you count the boxes down which is 4 and across which is one which makes it -4/1. So the slope is -4.
