Write the equation of the line in slope-intercept form.
(x/6) - (5/12)y = 5/8

Answers

The equation of the line in slope-intercept form is  y = (2/5)x + (-3/2)  .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is (x/6) - (5/12)y = 5/8 .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

(x/6) - (5/12)y = 5/8

On multiplying both sides of above equation by (12/5), we will get

   (2/5)x - y = 3/2

⇒ y = (2/5)x + (-3/2)                                                 equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = 2/5

Intercept = c = -3/2

The equation of the line in slope-intercept form is  y = (2/5)x + (-3/2) .

The equation of the circle with radius 1 and center at (-6 , 10) is (x + 6)^2 + (y - 10)^2 = 1.

The general form of the equation of  circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

A rental car company charges $48 per day to rent a car and $0.08 for every mile
driven. Bilquis wants to rent a car, knowing that:
. She plans to drive 175 miles.
. She has at most $110 to spend.
Write and solve an inequality which can be used to determine x, the number of days Bilquis can afford to rent while staying within her budget.

Answers

The number of days Bilquis can afford to rent while staying within her budget is 2 days.

How to solve the inequality

The question has the following data

amount charged =  $48

Rent per mile = $0.08

The mile to drive = 175 miles.

Amount to spend = 110 dollars

The inequality would be written as

48x + 0.08(175) ≤ 110

we are to solve for the value of x

this would be

48x + 14 ≤ 110

48x ≤ 110 - 14

48x ≤ 96

We have to divide through by 48

x ≤ 96 / 48

x ≤ 2

Hence we can say that the number of days Bilquis can afford to rent while staying within her budget is 2 days.

The diagrams below show two cereal boxes of different sizes and prices. (a) big box 500 g $8.00 small box 300 g $5.40 Which of the boxes is better value for money? Show your workings.​

Answers

Answer: Small box has the lowest amount when divided, that box has the best value.

Step-by-step explanation:

Given data,

Big box = 500 g

It cost is $8.00

Small box = 300 g

It cost is $ 5.40

First switch the box that's in kilograms into grams.

One kilogram=1000 grams.

Then,    Big box = 500 g = $ 8.00

            Small box = 300 g = $ 5.40

Next divide the amount in each box by the cost of each box.

           Big box = 500/8

           Big box  = 62.5

           Small box = 300/540

           Small box  = 0.5555

Therefore,

So, since small box has the lowest amount when divided, that box has the best value.

In the expression 38+27 y , which number is a coefficient?

Answers

27 is the number that is a coefficient.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

A coefficient is a number or an alphabet that is multiplied by a variable of a single term or the terms of a polynomial. For example, in the term 7x, 7 is the coefficient. The coefficient of x in the term 3xy is 3y.

The variable is a symbol for a value we don't know yet. It is usually a letter like x or y.

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.

In the expression 38 + 27y the coefficient of y is 27, 38 is the constant and y is the variable.

we can identify a coefficient since it is always associated with a variable.

Draw a right triangle with side lengths that form a Pythagorean triple. If you double the length of each side, is the resulting triangle acute, right, or obtuse? if you halve the length of each side? Explain.

Answers

If you double or halve the length of each of Pythagorean triplet the resulting triangle will always be Right Triangle.

Pythagoras Theorem states that the sum square of two sides of triangle is equal to the  square of longest side.

Let us take Pythagorean triplet as (6,8,10).

where base=6

perpendicular = 8

hypotenuse = 10

Part(a)

Let us double the length of each value

base = 12

perpendicular = 16

hypotenuse = 20

By Pythagoras Theorem

[tex]base^{2} +perpendicular^{2} =hypotenuse^{2}[/tex]

[tex]12^{2} +16^{2} =20^{2} \\ \\ 144+256=400\\ \\ 400=400[/tex]

Therefore the Triangle will be a Right Triangle as Pythagoras Theorem is satisfied.

Part (b)

Let us halve the length of each value

base=3

perpendicular = 4

hypotenuse = 5

By Pythagoras Theorem

[tex]base^{2} +perpendicular^{2} =hypotenuse^{2}\\\\3^{2} +4^{2} =5^{2}[/tex]

[tex]9+16=25\\ \\ 25=25[/tex]

Therefore the Triangle will be a Right Triangle as Pythagoras Theorem is satisfied.
