Answer

See below

Step-by-step explanation:

The given line has equation

[tex]5x - 2y =  - 6[/tex]

The slope intercept form is

[tex]y =  \frac{5}{2} x + 3[/tex]

The slope of this line is

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

The line perpendicular to this line has slope

[tex] -  \frac{2}{5} [/tex]

If this line passes through (5,-4), the point-slope form is

[tex]y + 4 =  -  \frac{2}{5} (x  - 5)[/tex]

The slope-intercept form is

[tex]y =  -  \frac{2}{5} x- 2[/tex]

The standard form is

2x+5y=-10

Answer:

a. 276 vehicles

Step-by-step explanation:

7⁄10[13½] + 3⁄10[20] + 3v - 3 = [4][5280]

[tex] \frac{10323}{( \frac{7}{10})(13 \frac{1}{2}) + ( \frac{3}{10})(20) + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 6 + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 9} = v \\ \\ \frac{10323}{18 \frac{9}{20}} = v \\ \\ 559 \frac{21}{41} = v[/tex]

Now, we check to see which answer choice this quantity is closer to. Obviously, we will take 896 and 276:

-559 21⁄41 + 896 = 336 20⁄41

559 21⁄41 - 276 = 28221⁄41 → we take this number

* 559 21⁄41 is much more closer to 276 than it is to 896.

Answer:

1 sq.unit = 9 sq.feet

Step-by-step explanation:

Length of shaded rectangle = 6 square on grid

We are given that Each square on the grid has a length of 1 unit.

So, Length of shaded rectangle = 6 units

Breadth of shaded rectangle = 4 square on grid = 4 units

Area of shaded rectangle = [tex]Length \times Breadth = 8 \times 4 = 32 units^2[/tex]

We are given that area of original square = 288 sq.feet

32 sq.unit = 288 sq.feet

1 sq.unit = [tex]\frac{288}{32} =9[/tex]

So, 1 sq.unit = 9 sq.feet

Hence Scale is 1 sq.unit = 9 sq.feet

The equation for the relationship between the number of pages left and number of hours is y = 555x - 555 * 444.

The relationship between the number of pages left to read (y) and the number of hours (x) can be represented by a linear equation.

Naoya reads at a rate of 555 pages per hour, which means he reads 555 pages in one hour. In 444 hours, he read 555 * 444 pages.

So, the equation for the relationship between the number of pages left and the number of hours is:

y = 555x - 555 * 444

In this equation:

- y represents the number of pages left to read.

- x represents the number of hours.

- 555x represents the number of pages he reads in x hours (555 pages per hour).

- 555 * 444 represents the total number of pages he read in 444 hours.

In mathematical operations, the direction can be from left to right or right to left, but in general, operations are performed according to the BODMAS/PEDMAS rule, which directs us from left to right.

In mathematical operations, the direction can be either from left to right or right to left, this largely depends on the specific operation field. However, in general, mathematics operations follow the BODMAS/PEDMAS rule, and the operations are performed from left to right.

The rule simply states: Brackets, Orders (exponential, square roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right). If you have, for example, a problem like 3 + 4 * 2, you would first perform the multiplication (4*2 = 8), then add the answer to 3, for a total of 11.

the opposite number sentence is 10=7+3

The opposite number sentence 10 - 7 = 3 will be 10 = 3 + 7.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The sentence is given below.

10 - 7 = 3

Simplify the equation, then the equation can be written as,

10 - 7 = 3

10 = 3 + 7

Answer:

y = 12x + 50

Step-by-step explanation:

Given,

The fixed amount of monthly allowance = $ 50,

Also, the earning per hour = $ 12,

If she works x hours in a month,

Then her total earning in x hours = 12x,

Also, total earning for a month ( say y ) = earning for x hours + fixed allowance

⇒ y = 12x + 50

Which is the required linear equation.

Answer:

21 / 99

Step-by-step explanation:

You want to get rid of the decimals so

Let x = 0.21212121

then 100x = 21.21212121

then 100x - x = 21

99x = 21

x = 21 / 99

So 0.2121... is equal to 21 / 99

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. The fraction equivalent of the decimal is 21/99.

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. Let x = 0.21212121... . Multiplying both sides of the equation by 100 gives 100x = 21.21212121... . Subtracting the original equation from this, we get 99x = 21, which means x = 21/99. Therefore, the decimal 0.21212121... is equal to the fraction 21/99.

Answer:

Here's what I get  

Step-by-step explanation:

Each digit in a  number has a place value, based on its distance from the decimal point.

The value of a digit  is the digit multiplied by its place value.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.  

Numbers to the left of the decimal point increase in the order: ones, tens, hundreds, thousands, etc.

Numbers to the right of the decimal point decrease in the order: tenths, hundredths, thousandths, etc.

So, we put the digits of 5.55 on the chart according to their place value.

Answer:

T'(2, - 5 )

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ), thus

T(- 2, 5 ) → T'(2, - 5 )

After a 180-degree rotation about the origin, the coordinates of point T' that is the image of T(-2,5) are (2,-5).

The coordinates of point T' after a rotation of 180 degrees about the origin are found by changing the signs of the original coordinates. The point T(-2,5) will thus be mapped to point T'(2,-5). This is because the 180-degree rotation reverses the direction of both the x and y coordinates. So, if the original point T has coordinates (x, y), then the rotated point T' will be (-x, -y).
