Answer:

b x 8 = 40 and 40 / 8 =b

Step-by-step explanation:

well, 8 charms makes one bracelet, so add up 8 until you run out of charms:

We only have 40 charms, so we can make 5 bracelets!

Now, plug this number (5) back into the equations:

b x 8 = 40

(5) x 8 = 40

40 = 40

this checks out!

40 - 8 = b

40 - 8 = (5)

32 = 5

32 does not equal 5, so this equation doesn't work.

40 / 8 = b

40 / 8 = (5)

5 = 5

This equation works :)

b + 8 = 40

(5) + 8 = 40

13 = 40

13 does not equal 40, so this is also a bad equation..

since b x 8 = 40 and 40 / 8 = b both produced the right results, we know those two are our answers!

y-intercept= 0

asymptote =[tex]lim_{n}[/tex]→-0 (8/x) = -∞

[tex]lim_{n}[/tex]→+0 (8/x) = +∞

range = R : { x ∈ R / {0} }

What is Range ?

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

I think the formula is:

f(x) = 8/x

(You wrote 8x; since a linear function has no asymptotes and you wrote 8x, I'm assuming the true function was 8/x.)

The amount that makes f(x) equal to 0 is the y-intercept.

Keep in mind that there is no value of x such that 8/x = 0 (because the quotient cannot be zero if the numerator is never zero).

Therefore, there is no y-intercept.

The asymmetry:

These are the four:

If the negative side of x tends to zero, then 8/x tends to negative infinity.

If x from the positive side approaches to zero, then 8/x tends to positive infinity.

These two asymptotes are expressed as follows:

[tex]lim_{n}[/tex]→-0 (8/x) = -∞

[tex]lim_{n}[/tex]→+0 (8/x) = +∞

Additionally, there are two cases where x tends to plus infinity (and 8/x goes to zero) and when x tends to minus infinity, where the function tends to zero once more. These two cases are denoted by the formulas:

[tex]lim_{n}[/tex]→-∞ (8/x) = -∞

[tex]lim_{n}[/tex]→∞ (8/x) = +∞

Lastly, the scope:

Only on limitations, y never reaches the following value:

y = 0

If so, the set of all real numbers excluding zero is the range, or

R : { x ∈ R / {0} }

Hence, y-intercept= 0

asymptote =[tex]lim_{n}[/tex]→-0 (8/x) = -∞

[tex]lim_{n}[/tex]→+0 (8/x) = +∞

range = R : { x ∈ R / {0} }

For the given parallel lines with transversal ,and the pair of interior angles 72° and (7x +24)°, the value of x = 12°.

As given in the question,

Two parallel lines with transversal are given.

72° and (7x +24)°are pair of interior angles

Simplify the given relation to get the value of x we have,

72° + (7x +24)° =180°

⇒ 7x + (72 +24)° =180°

⇒ 7x + 96° = 180°

⇒ 7x = 180° - 96°

⇒ 7x = 84°

⇒ x = 84° /7

⇒ x = 12°

Answer:

(1,3)

Step-by-step explanation:

You are at (-3,5).  Ordered pairs are written (x,y)  The x tells you how far right or left you are from the origin (0,0) and the y tells you how high above or below You are from the origin (0,0).

(-3+ 4,5 -2)  We are 3 unit to the right of (0,0) to begin with and the directions tell us to go 4 more units right.  We will now be 1 units to the right of zero.  We started at 5 units above zero, the directions tells us to move two units down.  That would be at 3.

So, our new order pair will be (1.3)

Since there are 128 fluid ounces in one gallon, we need to divide 14 by 128 to change ounces into gallons.

Since there are 60 minutes per hour, we need to multiply 14 by 60 to change per minute into per hour.

Combining these:  14 fl oz / min x (1 gal / 128 fl oz) x (60 min / hr)  =  6.5625 gal per hour.

Written as a mixed fraction:  6 9/16 gal per hour.

So, 79 + X = 180

         X=101 degrees.

Y is 79 degrees because it is an alternate interior angle to the other 79 degree angle.

Z is 101 degrees because X and Z are corresponding angles, which means they are equal.

If Z is 101 degrees, Y must be 79 degrees because Y and X make up a straight angle.

Answer:

63.7 inches to nearest tenth.

Step-by-step explanation:

The legs of the right triangles formed are 21 inches and 1/2*18 = 9 inches.

So, the hypotenuse (which is one of the congruent sides of the isosceles triangle)

= √(21^2 + 9^2

= √522 inches

Therefore, the triangles perimeter

= 2 * √522 + 18

= 63.695 inches.

The possible coordinates of the other points are (3 + √7, -1) and (3 - √7, -1)

From the question, we have

Where (x, -1) represents the other points

The distance between the points is the number of units between them

It is calculated using the following distance formula

d = √[(x₁ - x₂)²+ (y₁ - y₂)²]

Where x and y represent the coordinates of the given points

Substitute the known values in d = √[(x₁ - x₂)²+ (y₁ - y₂)²]

So, we have

d = √[(3 - x)²+ (2 + 1)²]

Evaluate the expression

d = √[(3 - x)²+ 9]

Recall that d = 4

So, we have

√[(3 - x)²+ 9] = 4

Square both sides

(3 - x)²+ 9 = 16

This gives

(3 - x)² = 7

So, we have

3 - x = ±√7

Solve for x

x = 3 ± √7

Hence, the coordinates are (3 + √7, -1) and (3 - √7, -1)

The above relation is not a function

What is a function?

A function from either a set X to just a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. The Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi are credited with the first known attempt to the concept of function. Originally, functions were the idealization of how a variable quantity depended on another quantity. A planet's location, for example, is a function of time. Historically, the notion was developed with the infinitesimal calculus at the end of the 17th century, and the functions investigated were differentiable until the 19th century.

The balcony can hold 25 people of 160-pound weight.

According to the question,

We have the following information:

The maximum weight balcony can hold = 1816 kg

Weight of 1 person = 160 pound

Now, we will convert this weight into kilogram so that both the measurements have same units.

1 pound = 0.454 kg

160 pound = 160*0.454 kg

160 pound = 72.64 kg

Now, let's take the number of people balcony can hold to be x.

So, we have:

72.64x = 1816

x = 1816/72.64

The equation of the parabola in intercept form exists

y = -2/7(x + 14)(x + 2).

The intercept form exists y = a(x - r)(x - s), where r and s exists the x-intercepts on the graph. The intercept form will tell us if there exists two x-intercepts, one x-intercept, or no x-intercepts.

Let x-intercepts of -14 and -2; passes through (-16, -8)

The equation of the parabola in intercept form y = a(x - r)(x - s)

substitute the values in the above equation, and we get

-8 = a(-16 + 14)(-16 + 2)

simplifying the above equation, we get

-8 = a(-2)(-14)

B) The extra punch she can make = 20litres

C) The ratio of fruit juice and lemonade for second batch = 7:6

What is Ratio?

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

A)

Let 3x be fruit juice and 2x be the lemonade

3x + 2x = 35litres

5x = 35

x = 35/5

x = 7

Then, required ingredient she needed

Fruit juice = 3x7 = 21 litres

Lemonade = 2x7 = 14 litres

B)

According to question

The amount of fruit juice she had = 12litre

Let x be 12litre

as we know that the ratio of fruit juice to the lemonade is 3 : 2

Thus,

Fruit juice = 3(x) = 12 litres

                    x = 12/3

                    x = 4

Fruit juice = 3 x 4 = 12litres

putting the value in lemonade

Lemonade = 2(4) = 8 litres

So, The extra punch she can make :

12 + 8 = 20litres

C)

The ratio for new second batch she added 4litres in lemonade

Then it become :

Fruit juice = 21 litres

Lemonade = 14 litres + 4litres = 18
