A rectangle is dilated by a scale factor of y to create a new rectangle. The area of the new rectangle is y2 times the area of the original rectangle.
True or false ?
Please help
Answer: True
Step-by-step explanation:
Suppose the length and width of the original rectangle is L and W
After dilation by a factor of y, it becomes yL and yW
Area of the original rectangle [tex]A_1=L\times W[/tex]
The area of the dilated rectangle is [tex]A_2=yL\times yW=y^2LW[/tex]
we can see that
[tex]\Rightarrow A_2=y^2A_1[/tex]

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19
A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error
Answer
b
Step-by-step explanation:
Answer:
B) There is an error in step 2.
Step-by-step explanation:
When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).
After combing your like terms, you now have the equation 2x+14=24.
You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10
This is where the student made the mistake. Instead of subtracting 14, they added 14.
The final step would be to divide by 2 on both sides.
At the end of the problem, you are left with x=5.

Bella bought packs of stickers to give to her friends. Each pack cost $4. She spent a total of $12 on stickers. How many packs did she buy?
Which equation best represents the statement above?
Question 2 options:
12s = 4
4s = 12
4 + s = 12
12 + s = 4
Given:
Bella bought packs of stickers to give to her friends.
Cost of each pack of stickers = $4
Total amount spent on packs of stickers = $12
To find:
The equation for the given statement.
Solution:
Let s be the number of packs of stickers.
Cost of one pack of stickers = $4
Cost of s packs of stickers = $4s
Total amount spent on packs of stickers is $12. So,
[tex]4s=12[/tex]
Therefore, the correct option is B.

How do I find the center and angle of rotation
9514 1404 393
Answer:
B → XC → YD → Z180° rotation about the originStep-by-step explanation:
In general, if PQ is rotated to P'Q', the center of rotation (O) will be the point of intersection of the perpendicular bisectors of PP' and QQ'. The angle of rotation will be the angle POP', or QOQ'.
__
The correspondence between preimage vertices ABCD and image vertices can be found by naming the vertices in the same order (clockwise) from one whose correspondence you know.
Here, the correspondence between A and W is given. Vertices clockwise from W are WXYZ, so those are the image points corresponding to ABCD.
__
We note that the midpoints of AW and BX are coincident at the origin. That is, the perpendicular bisectors of these segments are coincident at the origin, so the origin (point O) is the center of rotation. The rotation angle is AOW, an angle that measures 180°.
__
The image point coordinates are the opposites of the preimage point coordinates.
A(2, 2) ⇒ W(-2, -2)
B(2, 5) ⇒ X(-2, -5)
C(5, 5) ⇒ Y(-5, -5)
D(5, 2) ⇒ Z(-5, -2)
This is another indication that the rotation is 180° about the origin, since that rotation results in the mapping ...
(x, y) ⇒ (-x, -y) . . . . . rotation 180° about the origin

The higher the temperature of the air in the oven, the faster a cake will bake. Identify the independent variable. A.Time needed to bake the cake B.Type of oven C.Cake flavor D.Oven temperature
Answer:
Option D is correct
Step-by-step explanation:
An independent variable is a variable that does not change with a change in the other variables. For example, the height of a person is an independent variable.
Given: The higher the temperature of the air in the oven, the faster a cake will bake.
The independent variable is Oven temperature.
Therefore,
Option D is correct

The approximate areas of two states are listed below.
Texas: 2.69×10^5 square miles
Rhode Island: 1.21×10^3 square miles
Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.
Answer: _________________ square miles
Answer:
2.6779*10^5
Step-by-step explanation:
2.69 * 10^5 - 1.21 * 10^3
This is 2.6779*10^5 :)
The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the area of Texas be p = 2.69 x 10⁵ miles²
Let the area of Rhode Island be q = 1.21 x 10³ miles
Now , the difference of areas A = p - q
On simplifying the equation , we get
The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles
A = 10³ ( 2.69 x 100 - 1.21 )
On further simplification , we get
A = 10³ ( 269 - 1.21 )
A = 267.79 x 10³
A = 2.6779 x 10⁵ miles²
Hence , the difference in areas is 2.6779 x 10⁵ miles²

What is the equation of the line that passes through the point (-7,-4) and has an undefined slope?
Answer:
When the slope is UNDEFINED, that means the denominator of the slope formula is ZERO .
Slope formula = (y2 - y1)/(x2 - x1), and the graph is a VERTICAL line and the equation of the line is x =7 . Point (7, -4) is a point on the line.
