Answer:

y = - 5x

Step-by-step explanation:

given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

to find k use the condition y = - 10 when x = 2 , then

- 10 = 2k ( divide both sides by 2 )

- 5 = k

y = - 5x ← equation of variation

We need to reflect the given quadrilateral across the x-axis.

When we reflect a point across the x-axis, we need to negate the y-coordinate and leave the x-coordinate the same

The point of the given quadrilateral are:

(5,-2)

(2,-4)

(4,-8)

(7,-5)

When we reflect these points on the x-axis, the new points are:

(5,-(-2) = (5,2)

(2,-(-4)=(2,4)

(4,-(-8) =(4,8)

(7,-(-5)=(7,5)

What is an expression?

An expression, often referred as a mathematical model, is a continuous collection of signs that are well-formed in accordance with context-dependent principles. Numbers (predictor variables), parameters, processes, functions, brackets, capitalization, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's sequence of actions and other features. In algebra, a value might well be designated by an expression; this value may rely on the values given to the variables that the expression contains. The semantics associated with the symbols in the expression determine this value. The expression's development gains which meaning to use. It is unclear if two λ expressions are equivalent. The idioms used to represent hard figures are the same way.

Charles spent 60 hours picking up litter if each student spent the same amount of time.

According to the question,

We have the following details:

Charles and 7 other students spent a total of 480 hours picking up litter last year.

So, the total number of students including Charles are 8.

8 persons = 480 hours

So, we have to find time spent in hours for 1 person:

1 person = 480/8 hours

1 person = 60 hours

So, this one person can be any eight of them including Charles.

Hence, Charles spent 60 hours picking up litter last year with other 7 students.

What is mean by Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

g (x) is the indicated transformation of f (x).

The rule of f (x) is,

f (x) = - x + 5 ; horizontally translation 2 units left.

Now,

The rule of f (x) is,

f (x) = - x + 5 ; horizontally translation 2 units left.

Since, g (x) is the indicated transformation of f (x).

So, g (x) = f (x + 2)

Hence, We get;

g (x) = - (x + 2) + 5

      = - x - 2 + 5

      = - x + 3

Thus, The rule of the function g (x) will be;

(a) The total installment price is $5256  .

(b) The carrying charges is $1256 .

(c) The number of months needed to save the money at the monthly rate to buy the car for its cash price is  28 months .

In the question,

it is given that

Price of the car in cash = $4000

amount to be paid as installment per month = $146

time for installment = 36 months

Part(a)

the total installment price can be calculated using the formula

total price = (per month installment) * (number of months)

Substituting the values , we get

total price = 146*36

= 5256

So , total installment price = $5256

Part(b)

the carrying charges can be calculates using the formula

carrying charges = total installment price - price in cash

Substituting the values ,we get

carrying charges = 5256-4000

= 1256

So, carrying charges = $1256

Part(c)

the number of months needed to save the money at the monthly rate to buy the car for its cash price , can be calculated using the formula .

number of months = (price in cash)/(monthly rate)

= 4000/146

= 27.39

rounding , we get

≈ 28

number of months = 28 months

Therefore , (a) The total installment price is $5256  .

(b) The carrying charges is $1256 .

Answer:

Parallel to x+y=6

x+y-x=6-x

y=-x+6

y=mx+b

Slope: m=-1

As the line is parallel must have the same slope:

m=-1

And it passes through the origin, then b=0

y=mx+b

y=(-1)x+0

y=-x

In standard form:

y+x=-x+x

Answer: The equation of the line, in standard form, that passes through the origin and is parallel to x+y=6 is x+y=0

Step-by-step explanation:

The ordered pairs A. (−6, −14) and B. (−1, −7) in the form (x, y) are solutions to the equation 7x-5x=28.

A pair is considered to be ordered when two elements are written inside parantheses and are separated by a comma. The ordered pair (x, y), for instance, is represented by the notation (x, y), where 'x' is referred to as the first element and 'y' as the second element.

Depending on the context in which they are used, these elements—which can either be variables or constants—have different names. In a pair of elements that are ordered, the elements' order is somewhat significant. This indicates that (x, y) might not always be equal to (y, x).

We have given the equation 7x – 5y = 28

we know that a ordered pair (x,y)  must satisfy the equation

So let us do trial and error method

A. (−6, −14)

7(-6) – 5(-14) = 28

-42 + 70 = 28

28 = 28

ordered pair (−6, −14) in the form (x, y) satisfy for 7x – 5y = 28

B. (−1, −7)

7(-1) – 5(-7) = 28

-7 + 35 = 28

28 = 28

ordered pair (−1, −7) in the form (x, y) satisfy for 7x – 5y = 28

C. (4, 10)

7(4) – 5(10) = 28

28 - 50= 28

22 ≠ 28

ordered pair (4, 10) in the form (x, y) doesn't satisfy for 7x – 5y = 28

D. (7, 9)

7(7) – 5(9) = 28

49 - 45= 28

4 ≠ 28

ordered pair (7, 9) in the form (x, y) doesn't satisfy for 7x – 5y = 28

Thus, the ordered pairs A. (−6, −14) and B. (−1, −7) in the form (x, y) are solutions to the equation 7x-5x=28.
