Answer:

let x and y be the two number then according to question ,

xy=4 2/9

or, xy= 38/9

if one of the number is 38 then,

38x=38/9

or, x= 1/9 is the correct ans.

Answer:

Step-by-step explanation:

m:  y = -2x + 4

n:    y = x - 1

l:      y = 4

p:     x = -4

m: y=-2x+4

slope: 2

2/1=2

Its negative because the line is going down from left to right

y-intercept:

it crosses the y axis at (0,4)

n: y=x-1

slope: 1

1/1=1

Its positive because the line is going up from left to right

y-intercept:

it crosses the y axis at (0,-1)

l: y=4

slope: 0

A vertical line's slope is always 0

y-intercept:

it crosses the y axis at (0,4)

p: x=-4

To find the equation for a horizontal line, you need to find what x always is no matter what.

Answer:

28

Step-by-step explanation:

The Distributive property uses the number outside the parenthesis and combines it (using multiplication) with the ones inside.

So, the number 7 will be multiplied with the numbers inside the parenthesis.

7(11-7)

7 × 11 = 77

7 × -7 = -49 (It will just be the same way you multiply but with a added negative sign.)

77-49=

Answer:

The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.

Answer:

K (2,-4)

L (4,-6)

J (2,-9)

Step-by-step explanation:

The required graph of the image of △JKL after a reflection over the line y=x has been attached below.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The triangle △JKL is given in the represented graph, which vertices are as follows :

J (-9, 2)

K (-4, 2)

L (-6, 4)

The image of △JKL after a reflection over the line y = x will be triangle △J'K'L' that vertices are as follows :

K' (2,-4)

L' (4,-6)

J' (2,-9)

Hence, the required graph of the image of △JKL after a reflection over the line y=x has been attached below.

Answer:

Reyna Puti sold = 20 bottles

Step-by-step explanation:

Silver duck = Php 10 per bottle

Reyna Puti = Php 15 per bottle

Silver duck sold = 30 bottles

Reyna Puti sold = x bottles

Total sales = Php 600.00

Total = cost of Silver duck * number sold + cost of Reyna Puti * number sold

600 = 10 * 30 + 15 * x

600 = 300 + 15x

600 - 300 = 15x

300 = 15x

x = 300/15

x = 20 bottles

Reyna Puti sold = 20 bottles

Answer:

second which would be c for edg

Step-by-step explanation:

The term "off" indicates that the price of the item is reduced by the percentage off. Sales tax is however, added to the price of the item.

The total cost of the video game console is: [tex]\$476.85[/tex]

Given that:

[tex]Game = \$528[/tex]

15% off means that, the price is reduced by 15%.

So, we have:

[tex]Sales =Game - Game \times 15\%[/tex]

[tex]Sales = \$528 - \$528 \times 15\%[/tex]

[tex]Sales = \$528 -\$79.2[/tex]

[tex]Sales = \$448.8[/tex]

The total cost (when the sales tax of 6.25% is added) is:

[tex]Total = Sales + Sales \times 6.25\%[/tex]

[tex]Total = \$448.8 + \$448.8 \times 6.25\%[/tex]

[tex]Total = \$448.8 + \$28.05[/tex]

[tex]Total = \$476.85[/tex]

Hence, the total cost of the video game console is: [tex]\$476.85[/tex]
