Answer:

Zelie should have divided both numbers by 14

Step-by-step explanation:

Given

[tex]Actual = 28[/tex]

[tex]Measured = 14[/tex]

Required

Spot and correct Zelie's mistake

[tex]Zelie = \frac{28 - 7}{14 - 7} = \frac{21}{7}[/tex]

Scale is calculated as:

[tex]Actual = Measured * Scale[/tex]

[tex]28 = 14 * Scale[/tex]

Divide 28 and 14 by 14

[tex]28/14 = 14/14 * Scale[/tex]

[tex]2 = 1 * Scale[/tex]

[tex]2 =Scale[/tex]

[tex]Scale = 2[/tex]

Notice at this point:

[tex]28/14 = 14/14 * Scale[/tex]

Both sides were divided by 14.

Hence, option A answers the question.

A. Zelie should have divided both numbers by 14.

Answer:

m = rise over run

Rise: y/2 - y/1

Run: x/2 - x/1

m = slope

(x_1, y_1) = coordinates of first point in the line

(x_2, y_2) = coordinates of second point in the line

Step-by-step explanation:

Answer:

slope= (y2-y1)/(x2-x1)

1) (2-1)/(3-2)

=m=1

3) (5-4)/(2-2)

= UNDEFINED (vertical line)

5) (-6-6)/(3-(-3)

(-12/6)

= -2

CHECK

y=mx+b

6=-2(-3)+b

6=6+b

b=0

y=-2x connects both of these points on a graph

Answer:

The measure of ∠JKL is 65°

Step-by-step explanation:

Consider the provided diagram.

We need to find the degree measure of ∠JKL.

It is given that ∠JKM=45° and ∠MKL=x°

Also it is given that the measure of angle JKL can be represented using the expression 3x + 5.

Thus ∠JKL=3x+5

From the figure it can be concluded that ∠JKL is equal to the sum of ∠JKM and ∠MKL

This can be written as:

∠JKL = ∠JKM+∠MKL

Substitute the respective values in the above equation.

3x+5 = 45+x

Subtract x and 5 from both the sides.

3x+5-x-5 = 45+x-x-5

2x = 40

x = 20

Thus, the measure of ∠MKL=20°

Substitute the value of x in ∠JKL = 3x+5.

∠JKL = 3(20)+5

∠JKL = 60+5

∠JKL = 65

Hence, the measure of ∠JKL is 65°

Answer:

x= -1/5

Step-by-step explanation:

1

Add 9x9x to both sides.

x+9x=-2x+9x=−2

2

Simplify  x+9xx+9x  to  10x10x.

10x=-210x=−2

3

Divide both sides by 1010.

x=-\frac{2}{10}x=−102

4

Simplify  \frac{2}{10}102  to  \frac{1}{5}51.

x=-\frac{1}{5}x=−51

In stand collection, Stan owns less than 9 cards.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Let x represnets the number of Kyle's cards and y be the number of Stan's cards.

We know that Kyle has 22 more cards than 3 times the number of cards that Stan owns, so:

k = 3s + 22 equation (1)

We also knows that together, they own less than 58 cards, so:

k + s < 58 equation (2)

Replace (1) in (2) and solve for :

s + 3s + 22 <58

s <58

Hence, Stan owns less than 9 cards.

Step-by-step explanation:

Hey there!

Given; The points are; (19,14) and (21,19).

Note: Use slope formula.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

Put all values.

[tex]m = \frac{19 - 14}{21 - 19} [/tex]

Simplify it.

[tex]m = \frac{5}{2} [/tex]

Therefore, slope(m)= 5/2.

Hope it helps...

Answer:

slope = 5/2

Step-by-step explanation:

[tex]m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }[/tex]

[tex]\frac{19-(14)}{21-(19)}[/tex]

m=[tex]\frac{5}{2}[/tex]

Answer:

$25.97

Step-by-step explanation:

You want to find 70% of $35.00 because there is a 30% markdown meaning 70% of the original price. 70% is the same as 7/10.

to get the price after markdown multiply $35.00 by 7/10 which equals $24.5

Multiply $24.5 by .06 to get the sales tax which is $1.47

So the sales tax is $1.47 and the price after markdown is $24.5 so take the sum of both. $1.47 + $24.5 = $25.97

The cost of Tyler's jacket is $23.03.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Tyler bought a jacket regularly priced $35.00.

With a 30% markdown, the cost of jacket is

30% of 35

= 30/100 ×35

= 0.3×35

= 10.5

So, the cost of jacket is 35-10.5=$24.5

Now, sales tax on $24.5

That is, 6% of $24.5

= 6/100 ×24.5

= 0.06×24.5

= 1.47

Cost of jacket is 24.5-1.47

= $23.03

Therefore, the cost of Tyler's jacket is $23.03.

Answer:

The correct option is;

y = 6

Step-by-step explanation:

The reflection of the figure of a preimage over a line of symmetry will form an image that the same coordinates as the preimage.

The line of symmetry is a line or axis that goes through the geometric figure's center and outlines the division of the the figure into two identical, symmetrical parts

The appearance of the figure on one side of the line of symmetry is a reflection of the image on the other side of the line of symmetry

In the figure included in the question, given that the shape of the figure is a rectangle the line of symmetry will be a line passing through the midpoint of a chosen side and parallel to the side adjacent to the chosen side

Therefore, the lines of symmetry are x = 4.5 and y = 6. Therefore, the most correct of the given options is y = 6.

   Option A will represent the line of reflection.

 A rectangle has two pairs of vertices. If one pair reflects over a line in such a way that it replaces the other pair, line is said to be the line of reflection.

If the pair of points A,B replaces the other pair C,D, line of reflection will be y = 6.

Similarly, the pair of vertices A,C replaces other pair B,D, line of reflection will be x = 4.5.

   Therefore, line given in Option A will represent the line of reflection.
