Given the preimage and image, find the dilation scale factor​
Given the preimage and image, find the dilation scale factor​ - 1

Answers

Answer 1
Answer:

Answer:

1/2

Step-by-step explanation:

the dilation factor should be 1/2

  1. if u count the dots on the sides of the preimage there are 2 dots that's the length
  2. if u count the dots on the real image it's 4
  3. therefore 2/4 to it's lowest term is 1/2
  4. so 1/2 is the scale factor
Answer 2
Answer:

Answer:

should be 1/2 as your answer

Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his. Let r equal the number of stamps Chris has. Which expression represents the number of stamps Erykah has? (Let r = the number of stamps Chris has)A. 6 - 3r
B. 3r + 6
C. 3r - 6
D. 6 + 3r

Answers

C. 3r-6 is the answer

Answer:

C

Step-by-step explanation:

let r be the number of stamps Chris has then

3times this amount is 3r and less 6 is subtract 6 from 3r, hence

Erykah has 3r - 6 stamps → C

48 divided by 6 gives you 8.

Which system of equations can be graphed to find the solution(s) to 4x2 = x2 – 7?

Answers

4x^2 = x^2 - 7

In order to find the solution by graphing we need to make two equation with x and y terms

we use Left hand side 4x^2 for first equation and right side x^2 -7 for second equation.

So the equation becomes

first equation y=4x^2

Second equation y= x^2 - 7

y= x^2 \ and \ y= x^2-7 are the system of equations that can be graphed to find solution

The system of equations that can be graphed to find the solutions of the equation 4{x^2} = {x^2} - 7 are \boxed{y = 4{x^2}{\text{ and }}y = {x^2} - 7}.

Further explanation:

Given:

The equation is 4{x^2} = {x^2} - 7.

Explanation:

The given equation is 4{x^2} = {x^2} - 7.

The left hand side of the equation is 4{x^2}

The right hand side of the equation is {x^2} - 7.

Consider the left hand side as y.

y = 4{x^2}

Consider the right hand side as y.

y = {x^2} - 7

The two equations are y = {x^2} - 7 and y = 4{x^2}

The system of equations that can be graphed to find the solutions of the equation 4{x^2} = {x^2} - 7 are \boxed{y = 4{x^2}{\text{ and }}y = {x^2} - 7}.

Factorise it step by step
4r²-7r+3

Answers

To factor the quadratic expression 4r² - 7r + 3, we can use the factoring method. We're looking for two binomials in the form (ar + b)(cr + d) where ac = 4, ad + bc = -7, and bd = 3. Here's how to factor it step by step:

Step 1: Multiply the leading coefficient (4) by the constant term (3). This gives us 4 * 3 = 12.

Step 2: Find two numbers that multiply to 12 (the result from step 1) and add up to the middle coefficient (-7). These numbers are -4 and -3 because (-4) * (-3) = 12, and (-4) + (-3) = -7.

Step 3: Rewrite the middle term (-7r) using the numbers from step 2 (-4 and -3). We split the middle term like this:
4r² - 4r - 3r + 3

Step 4: Group the terms and factor by grouping:
(4r² - 4r) - (3r - 3)

Step 5: Factor out the greatest common factor from each group:
4r(r - 1) - 3(r - 1)

Step 6: Now you can see that (r - 1) is a common factor in both terms. Factor it out:
(r - 1)(4r - 3)

So, the factored form of the quadratic expression 4r² - 7r + 3 is (r - 1)(4r - 3).

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle.Always, sometimes, or never

Answers

Answer:

Polygon: A polygon is a simple closed curve entirely made up of line segments.

1. As starting from triangle

Three kind of triangles: Isosceles, Scalene , and equilateral triangle

In none of these  measure of an exterior angle at the vertex of the triangle equals the measure of the adjacent interior angle.

2. Quadrilateral = Parallelogram, Rhombus, Rectangle, Square, Kite, Trpzm

Apart from Rectangle and Square none other quadrilateral have The measure of an exterior angle at the vertex of the quadrilateral equals the measure of the adjacent interior angle.

we can also consider other polygons also like pentagon,hexagon,heptagon.

Decagon and found that it is not always possible that measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle.

So, the correct option is Sometimes.
so an exterior angle at the vertex of a polygon not can being never equal the measure of the adjacent interior angle
