Answer:

x = - 4

Step-by-step explanation:

Given

2(x - 8) = x + 5x ← distribute left side and simplify right side

2x - 16 = 6x ( subtract 6x from both sides )

- 4x - 16 = 0 ( add 16 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Answer:

see explanation

Step-by-step explanation:

Multiply through by the lowest common multiple of u, v and f, that is uvf

uvf × [tex]\frac{1}{v}[/tex] + uvf × [tex]\frac{1}{u}[/tex] = uvf × [tex]\frac{1}{f}[/tex], that is

uf + vf = uv ← factor out f on the left side → (1)

f(u + v) = uv ← divide both sides by (u + v)

f = [tex]\frac{uv}{u+v}[/tex]

(b)

Using line (1)

uf + vf = uv ( subtract uv from both sides )

uf + vf - uv = 0 ( subtract uf from both sides )

vf - uv = - uf ← factor out v on the left side

v(f - u) = - uf ← divide both sides by (f - u)

v = - [tex]\frac{uf}{f-u}[/tex]

keeping in mind that perpendicular lines have negative reciprocal slopes, let's find the slopes of these two, if they're indeed perpendicular, they'll be negative reciprocal of each other, meaning one slope will be the same as the other, but negative and upside-down, and thus their product will just be -1.

Answer:

a ) total number of sixth in 5 ribbon will be 6\times 5 = 30

b) length of each sixth will be = 5.97 inches

Step-by-step explanation:

given data:

Number of pieces of ribbon is 5

each piece length 1 yard

total number of cut in one piece of ribbon = 6

a) one piece of ribbon consist of 6 sxiths

therefore total number of sixth in 5 ribbon will be 6\times 5 = 30

b) each ribbon length is 1 yard

so, whole ribbon is divided into 1\6 yard length which is length of individual division

we know that one yard is 36 inches

therefore, in 1/6 yard = 5.97 inches

Answer:

a.  She will have 30 sixths after cutting all the ribbons.

b. 6 inches.

Step-by-step explanation:

a. You know that the lenght of each piece of ribbon is 1 yard.

She cuts each ribbon into sixths, then the lenght of each one of them is:

[tex]\frac{1}{6}\ yd[/tex]

So:

[tex]\frac{6}{6}=1\ yard[/tex]

Since Faye has 5 pieces of ribbon, after cutting all the ribbons she will have:

[tex](5)(\frac{6}{6})=\frac{30}{6}[/tex]

She will have 30 sixths after cutting all the ribbons.

b. You need make the conversion from yards to inches.

A proof that square root of 2 is irrational. ... An equation x² = a, and the principal square root ... The number under the radical sign is called the radicand. ... the given square numbers, each product of square numbers is equal to what square ... are relatively prime -- and it will be impossible to divide n· n into m· m and get 2.

Step-by-step explanation:

Rational numbers are numbers that can be represented as a fraction of two integers. For [tex]\sqrt{76 + n}[/tex] and [tex]\sqrt{2n + 26}[/tex] to be rational, the smallest value of n is 5

Given that:

[tex]\sqrt{76 + n}[/tex] and [tex]\sqrt{2n + 26}[/tex] --- correct expressions

For both numbers to be rational, we should be able to represent the numbers as a fraction of two integers.

There are no straight ways to solve this, except trial by error.

When [tex]n = 1[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 1} = \sqrt{77} = 8.77496.......[/tex]

The above is not rational

When [tex]n = 2[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 2} = \sqrt{78} = 8.83176......[/tex]

The above is not rational

When [tex]n = 3[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 3} = \sqrt{79} = 8.88819......[/tex]

The above is not rational

When [tex]n = 4[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 4} = \sqrt{80} = 8.944271......[/tex]

The above is not rational

When [tex]n = 5[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 5} = \sqrt{81} = 9[/tex]

The above is rational

So, we try [tex]n = 5[/tex] for the second expression

[tex]\sqrt{2n + 26} = \sqrt{2\times 5 + 26} = \sqrt{10 + 26}=\sqrt{36}= 6[/tex]

The above is also rational

Hence, the smallest value of n that makes each of the expression rational is [tex]n = 5[/tex]

Answer: We start with 6 reams of copy paper and 8 teachers.

a) if we distribute the paper equally between all the teachers, then each teacher receive 6/8  (here we are dividing the total number of reams by the number of people that we are are splitting it). but 6/8 is less than one, so we must open the reams in order to split them.

b) If there were twice as many reams of paper, then we will have 2*6 = 12 reams of paper, and if there where half the number of teachers, then we have 8/2 = 4 teachers.

Doing the same procedure as before, we have 12 teams for 4 teachers, then each teacher has 12/4 = 3 reams

before, each teacher received 6/8 reams, and now, each one receive 3.

if we want to know the change, we need to see the difference between these numbers, so 3 - 6/8 =  3*8/8 - 6/8

notice that i am multiplying the 3 by 8/8, this is one, but  this way i can have the same denominator in both numbers.

24/8 - 6/8 = 18/8 = 9/4 = 8/4 + 1/4 = 2 + 1/4

so each teacher receive 2 + 1/4 reams than before.

Check the picture below.

so, bearing in mind that vertical angles are equal, thus ∡AED = ∡BEC, and we know that ∡BEC = 52 = ∡AED, so those two angles added up are 104°.

now, a circle has a total of 360°, if we take away those 104° from the red angles, what's leftover is just 256°, well, the green angles there are also vertical angles and thus twins, so each one will take half of 256°.

∡BEA = 128° = ∡CED.

to find the circumference of a circle you have to multiple the diameter by pi (3.14). so if you have the circumference already just switch around the equation (since you don’t know the diameter) to 10.99 divided by 3.14 to find the diameter and you get 3.5. but thats the diameter and you have to find the radius so divide 3.5 by two and you get 1.75 and 1.75 rounded to the nearest tenths is 1.8

Answer:

A. One pound of pistachios plus 1 pound of almonds cost $20

C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.

E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.

Step-by-step explanation:

Let

x ----> the cost of one pound pistachios

y ----> the cost of one pound of almonds

we know that

x=y+4 -----> equation A

2x+3y=48 -----> equation B

substitute equation A in equation B and solve for y

2(y+4)+3y=48

2y+8+3y=48

5y=48-8

y=8

Find the value of x

x=8+4 =12

therefore

The cost of one pound pistachios is $12 and the cost of one pound of almonds is $8

Verify all statements

case A) One pound of pistachios plus 1 pound of almonds cost $20.

Is True

x+y=$12+$8=$20

case B) The pistachios cost twice as much per pound as the almonds

Is false

Because

2y=2(8)=$16

$16≠$12

case C)  Reducing the number of pounds of almonds by 1 results in a total cost of $40

Is True

Because

2x+2y=2(12)+2(8)=$40

case D) The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48.

Is false

The equation will be

2(a + 4) + 3a = 48.

case E) The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48

Is true

Because

p=a+4

Solve for a

vertex = (4, - 25 )

Step-by-step explanation:

Given a quadratic function in standard form : f(x) = ax² + bx + c : a ≠ 0

The the x- coordinate of the vertex is

[tex]x_{V}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = x² - 8x - 9 ← is in standard form

with a = 1, b = - 8, thus

[tex]x_{V}[/tex] = - [tex]\frac{-8}{2}[/tex] = 4

Substitute x = 4 into f(x) for corresponding value of y

f(4) = 4² - 8(4) - 9 = 16 - 32 - 9 = - 25

vertex = (4, - 25 )

Answer:

vertex is (4,-25)

Step-by-step explanation:

[tex]f(x) = x^2 - 8x - 9[/tex]

To find out the vertex we use formula

[tex]x=\frac{-b}{2a}[/tex]

From the given f(x), the value of a=1, b=-8 and c=-9

Plug in the values in the formula

[tex]x=\frac{-(-8)}{2(1)}[/tex]

x=4

Now find the value of y

plug in 4 for x in f(x)

[tex]f(4) = 4^2 - 8(4)- 9=-25[/tex]

The value of y is -25

The vertex is (4,-25)

Answer:
