Let’s assume the initial coordinates are (x,y) while the dilated coordinates are (x',y').

Thus, the dilation process can be represented as:
(x,y)............> (x',y')

Now, let’s say the dilation factor is k.
Hence:
x' = kx
y' = ky

Using this information, the student simply needs to take the initial coordinates and final coordinates and substitute them into either of the equations above to solve for k.

Example:
Assuming an original point of (2,4) expands to (4,8). Determine the dilation factor.
Let k represent the dilation coefficient.
The coordinates (x,y) are (2,4) and (x',y') are (4,8)
Thus:
x' = kx.........> 4 = k*2..........> k = 2
Alternatively:
y' = ky..........> 8 = k*4.........> k = 2
Consequently, the dilation coefficient is 2.

Hopefully, this is helpful:)

Sample Response: Identify two corresponding ordered pairs from the two shapes. Determine how much the pre-image values were multiplied to achieve the image values, as this represents your scale factor. You can obtain this by dividing the coordinates of the image by the matching coordinates of the pre-image.

What is the equation of the line that passes through the point (5, 4) and has a<br> slope of 6/5?
babunello [8412]
The equation of the line through the point (5,4) with a slope of 6/5 is y = 6/5x - 2. This is determined using the linear equation format y = mx + b. By substituting in the values, you can simplify to find the y-intercept.

In the Ma-and-Pa grocery store, shelf-space is limited and must be used effectively to increase profit. Two-cereal items, Grano
Inessa [9000]
No. Allocate 2/3 of the space to Grano and 1/3 to Wheatie. This results in approximately 57% for Wheatie and 43% for Grano—meaning 60(.57)=34.2 ft² for Wheatie and 60(.43)=25.8 ft² for Grano. Therefore, there would be about 85.5 boxes of Wheatie and 129 boxes of Grano, leading to a total profit of 129(1)+85(1.35)=$243.75. The best choice would be to place 200 boxes of Grano and 50 boxes of Wheaties on the shelf. Allocating 40 ft² to Granos (200(.2)) and 20 ft² to Wheaties (50(.4)) means that 40/60=2/3=66.6% of the space would be for Granos, and 20/60=1/3=33.3% would be for Wheaties. The total profit would be 200(1)+50(1.35)=$267.5.

Simplify the given expression, using only positive exponents. Then complete the statements that follow. [ (x2y3)−1 (x−2y2z)2 ] 2
AnnZ [9099]

Answer: y²z⁴ / x¹²

  • The exponent for x is 12

  • The exponent for y is 2

  • The exponent for z is 4

Explanation:

1) The expression to simplify:

((x^2y^3)^{-1}(x^{-2}y^2z)^2)^2

2) Rule: power of a power:

(x^{-4}y^{-6})(x^{-8}y^8z^4)

3) Rule: product of powers with identical bases

x^{(-2-8)}y^{(-6+8)}z^4

4) Add up the exponents

x^{-12}y^2z^4

5) Transfer the negative exponent to the denominator:

\frac{y^2z^4}{x^{12}}

The exponent attached to x is 12, for y it is 2, and for z it is 4.

Select the sequence of transformations that will carry rectangle A onto rectangle A'. A) reflect over y-axis, rotate 90° clockwi
PIT_PIT [9117]

Answer:

Each of the 4 arrangements will produce a rectangle.

Explanation:

Transforming a rectangle through rotation or translation will not alter its rectangular shape. This principle also applies when reflecting it across any axis. Thus, every sequence among the four provided will result in a rectangle.

Tricia is going to write Patterns A , B , and C using the rule add 15. The first number in each pattern is shown below . Use the
Inessa [9000]

Response:

The number 40 can be found in Pattern B. Additionally, following the rule, each sequence will expand.

Detailed breakdown:

Let’s build each sequence. Recall that the guideline is to "add 15" to generate each sequence starting from the provided initial number.

Pattern A.

5+20+35+50+65+80+95+110+125+140+155+170+185+200+215+...

Pattern B.

10+25+40+55+70+85+100+115+130+145+160+175+190+205+...

Pattern C.

15+30+45+60+75+90+115+130+145+160+175+190+205+...

You can see that the number 40 appears in Pattern B. Moreover, per the rule, each pattern will show an increase.
