Based on the transformaion of point A, the coordinate of the point she would end up is (3, -4)

The complete question is added at the end of this solution

From the question, we have the following point

Starting point = (-3, 5)

The movement is given as

9 units down and 6 units to the right

The above can be represented mathematically as

(x, y) = (x + 6, y - 9)

When the above translation is applied on point A, we have the following equation

A' = (-3 + 6, 5 - 9)

Evaluate the sum and he difference in the above equation

A' = (3, -4)

Hence, the coordinate of the point she would end up is (3, -4)

If Samantha moved point A 9 units down and 6 units to the right, at what point would she end up?

Answer:

0.5 feet of snow

Step-by-step explanation:

6 inches is half of a foot because 1 foot = 12 inches.

6 inches / (12 inches / 1 foot) = 0.5 feet of snow

If 13 cents per yard is the price, and there was $8.63 left on the card, the yards of ribbon  Leila bought is 49 yards of ribbon.

To determine the number of yards of ribbon Leila bought, we need to calculate the difference between the initial balance on the prepaid debit card and the remaining balance after the purchase.

Initial balance: $15.00

Remaining balance: $8.63

The difference between these two amounts represents the amount spent on the ribbon:

$15.00 - $8.63 = $6.37

Now, we can calculate the number of yards of ribbon by dividing the amount spent by the price per yard:

$6.37 / $0.13 = 49

Therefore, Leila bought 49 yards of ribbon.

Step-by-step explanation:

The area that would be painted will be 144 square feet

From the question, we are to determine the area of the cube-shaped shed that was painted

From the given information,

The cube-shaped shed has 6-foot high walls

From the formula for the surface area of a cube,

Surface area = 6s²

Where s is the measurement of a side

A cube has six sides

Since, the floor and ceiling are not painted,

The area of the shed that was painted will be

Surface area painted = 4s²

s = 6 feet

Thus,

Surface area painted = 4 × 6²

Surface area painted = 4 × 36
Surface area painted = 144 square feet

Hence, the area that would be painted will be 144 square feet

Answer:

b = 8 , m = - 5

Step-by-step explanation:

For this question we can use simulteanous equations to solve for m and b.

We first come up with 2 equations.

Given the first condition:

23 = -3m + b

b - 3m = 23 (Equation 1)

Now the Second Condition:

-7 = 2m + b

b + 2m = -7 (Equation 2)

Now, we will use Equation 1 - Equation 2 to eliminate b to solve for m.

-3m - (+2m) = 23 - ( - 7)

- 5m = 30

m = 30 ÷ -6 = -5

Now we substitute m into Equation 1 to solve for b.

b - 3(- 5) = 23

b + 15 = 23

b = 23 - 15 = 8

Answer: m=-6    b=5

Step-by-step explanation:

f(x)=mx+b

f(-3)=23     f(2)=7

[tex]\displaystyle\\\left \{ {{23=(m)(-3)+b} \atop {-7=(m)(2)+b}} \right. \ \ \ \ \left \{ {{23=-3m+b\ \ \ \ (1)} \atop {-7=2m+b\ \ \ \ (2)}} \right.[/tex]

Subtract equation (2) from equation (1):

-30=5m

Divide both parts of the equation by 5:

-6=m

Thus, substitute m=-6 in (2):

-7=(-6)(2)+b

-7=-12+b

-7+12=-12+b+12

5=b

The most reasonable conjecture for the number of triangles in the eighth figure in the pattern is that there are 8 triangles in the eighth figure in the pattern

The given figure represents the given parameter

From the figure, we have the following parameters

When represented as a sequence, we have the following terms

4, 6, 8.....

The above sequence represents an arithmetic sequence with the following properties

First term, a = 4

Common difference, d = 2 i.e. 6 - 4

The most reasonable conjecture for the number of triangles in the eighth figure in the pattern is calculated by the following arithmetic sequence formula

Tn = a + (n - 1) * d

So, we have

T8 = 4 + (8 - 1) * 2

Evaluate

T8 = 18

Hence, the most reasonable conjecture for the number of triangles in the eighth figure in the pattern is that there are 8 triangles in the eighth figure in the pattern

Answer: the bus's speed on the level road was 65 milles per hour

Step-by-step explanation:

Let the bus's speed on the level road is x mph

Hence, the bus's speed on the winding road is (x-20) mph

Thus,

3(x)+5(x-20)=420

3x+5x-100=420

8x-100=420

8x-100+100=420+100

8x=520

Divide both parts of the equation by 8:

x=65 mph

Answer: The preimage and final image are the same point

This applies to every point in the xy plane.

======================================================

Explanation:

Let's say we started with the example point of (5,7)

Put the coordinates of the point into the T(x,y) transformation

We'll replace every x with 5 and every y with 7

So,

T(x, y) = (x+3, y-1)

T(5, 7) = (5+3, 7-1)

T(5,7) = (8, 6)

What does this mean? It means that the original preimage point (5,7) moves to (8,6). This is a shift of 3 units right and 1 unit down.

------------------

Now we'll plug the coordinates of that result, the (8,6), into the transformation of S(x, y) = (x-3, y + 1)

Plug in x = 8 and y = 6 to get...

S(x, y) = (x-3, y + 1)

S(8, 6) = (8-3, 6 + 1)

S(8, 6) = (5, 7)

We have gone from (8,6) to (5,7). We're back where we started.

The second transformation of (x-3, y+1) shifts 3 units left and 1 unit up. Notice both of these undo the original "3 units right and 1 unit down" from earlier. So this is why we get back to the starting point. It's not a coincidence.

Therefore, transformation T and transformation S are inverse transformations of one another. They undo each other. It's like taking a step forward (transformation T) and then taking a step back (transformation S)

In terms of algebra, it's like how multiplication and division are inverses of each other.

As you can probably guess, there's nothing particularly special about (5,7). I chose two random numbers. Pick whatever two favorite numbers you want for x and y. Plug them into T(x,y) and then whatever that result is, plug it into S(x,y) to notice you should get back to your original choice of (x,y). I recommend GeoGebra as a useful tool to help with geometric transformations.

The probability that the selected number is even is 7/15.

The probability that the selected number is a multiple of 4 is 1/5.

The probability that the selected number is a prime number is 2/5.

Based on the information illustrated, the following can be deduced:

Even numbers = 2, 4, 6, 8, 10, 12, 14.

Multiple of 4 = 4, 8 and 12.

Prime numbers = 2, 3, 5, 7, 11, and 13.

Therefore, the probability that the selected number is even will be:

The orders from the person whose depth was closest to the surface to the person whose depth was the farthest from the surface as:

Brenda < Tim  < Carlton < Ali

Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order. For example, a set of natural numbers are in ascending order, such as 1, 2, 3, 4, 5, 6, 7, 8… and so on.

If the information is sorted from highest to lowest, it is said to be in descending order. For example 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 are arranged in descending order. In other words, if the numbers are arranged from the largest to the smallest number, it is said to be in descending order.

We can write, four friends went scuba diving today,

Ali dove = 70 feet,

Tim went down = 50 feet,

Carl dove = 65 feet,

Brenda reach = 48 feet below sea level.

To determine the order from the person whose death was closest to the surface to the person whose death was the farthest from the surface.

Arrange in ascending order of distance from sea level.

Brenda < Tim  < Carlton < Ali

48feet < 50 feet < 65 feet < 70 feet
