x is an irrational number between 7 and 10. find a value for x

Answer:-115

Step-by-step explanation:

Use distributive property!

-5 times 20 = -100

-5 times 3 = -15

-100 - 15 = 115

Answer: the answer is -115

Step-by-step explanation:

Answer:

x + y + z = - 22

Step-by-step explanation:

Reciprocal of a : - 6,

Reciprocal of b : 2

Therefore if x is the sum of the reciprocals of a and b, it will be - 6 + 2 = - 4. x will be - 4.

Respectively if y is the product of the reciprocals of a and b, it will be - 6 [tex]*[/tex] 2 = - 12. y is - 12. And if z is twice the reciprocal of a / the reciprocal of b, it will be the following,

z = 2(- 6) / 2

= - 12 / 2 = - 6

And x + y + z = - 4 - 12 - 6 = - 22. That is your solution.

Answer:

the equation is 45 + 20x= 225 and her son had a total of nine (9) classes.

Step-by-step explanation:

45 + 20x = 225 is the equation.

to solve it, we do 225-45=180

then, 180/20= 9

so x = 9

Answer:

See below.

Step-by-step explanation:

We have the rational function:

[tex]\frac{4}{x^2-1}[/tex]

The domains of rational function are the zeros of the denominator. This is because if the denominator equals 0, they the function would be undefined.

Therefore, we need to find the zeros of the denominator. Set the expression in the denominator to zero:

[tex]x^2-1=0[/tex]

Solve for x. Add 1 to both sides:

[tex]x^2=1[/tex]

Take the square root of both sides:

[tex]x=\pm \sqrt1[/tex]

Simplify:

[tex]x=\pm 1[/tex]

So, the domain is all real numbers except for x=-1 and x=1.

In interval notation, this is:

[tex](-\infty,-1)\cup(-1,1)\cup(1,\infty)[/tex]

This is interpreted as all values until -1 not including -1 until all values until 1 not including 1, and then all values there on after.

In set notation, this is:

[tex]\{x|x\in\mathbb{R}, x\neq-1, 1\}[/tex]

Answer:

[tex]\large \boxed{\mathrm{All \ real \ numbers \ except} \ x=-1 \ \mathrm{and} \ x=1}[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{4}{x^2-1}[/tex]

The domain of a rational function is all the real numbers except the numbers for which the denominator is equal to 0.

Let the denominator equal to 0.

[tex]x^2-1=0[/tex]

Solve for x.

[tex]x^2 =1 \\ \\ \\ x= -1 \ \mathrm{or} \ x=1[/tex]

When x = -1 and x = 1, the function is undefined.

The domain of the function is all real numbers except x = -1 and x = 1.

Answer:

Hey there!

The domain is the range of all the x values.

Thus, the domain would be from -3 to 5 and would be written as -3≤x≤5.

Answer:

The translation would be

X = 40% + 5 + A

Step-by-step explanation:

First, translate the words, is, more than and 'the number'.

Is means equals (=).

More Than means plus (+).

'the number' can be x.

Now, put it together.

X(The Number) =(Is) 40% +(more than) 5 +(more than) A(a number)

I hope this helps!!

The expression of the number that is 40% more than five more than a number A will be mathematically given as 40% + 5 + A.

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

The concept of algebraic expressions is the use of symbols or alphabets to represent numbers by providing their precise values.

Translate the following into an algebraic expression:

The number that is 40% more than five more than a number A.

Then the expression will be,

⇒ 40% + 5 + A

The expression of the number that is 40% more than five more than a number A will be 40% + 5 + A.

Answer:

The value of the given expression is -4.5

Step-by-step explanation:

We need to find the value of the expression [tex]-3|5-s^3|+3t[/tex] when s=2 and t=1.5

Putting the values of s and t in the given expression.

So,

[tex]-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5[/tex]

We know that, |-a|=a

So,

[tex]=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5[/tex]

So, the value of the given expression is -4.5

Answer:

-13.5 is the correct answer.

Step-by-step explanation:

Step-by-step explanation:

x cos θ + y sin θ = x cos β + y sin β

Let's say x = cos A, and y = sin A.

cos A cos θ + sin A sin θ = cos A cos β + sin A sin β

Use angle sum formula.

cos(A − θ) = cos(A − β)

A − θ = ±(A − β)

A − θ = β − A

2A = θ + β

A = (θ + β) / 2

cot A = cot((θ + β) / 2)

x/y = cot((θ + β) / 2)

Take a look at the explanation below. It proves that 'x / y = cot(θ + β / 2)' using a different method.

Answer:

5 hours

Step-by-step explanation:

Ralph earned $197 in total but with an initial fee of $32 so,

197 - 32 = 165

$165 is the amount he made from the hourly fee alone. So let's divide the total by the hourly fee.

165 ÷ 33 = 5.

Answer:

k = 10

Step-by-step explanation:

30+2k+5k=100

Combine like terms

30 + 7k = 100

Subtract 30 from each side

30+7k-30 = 100-30

7k  = 70

Divide each side by 7

7k/7 = 70/7

k = 10

Answer:

k=10

Step-by-step explanation:

We are given the equation:

30+5k+2k=100

We want to find k, therefore we must isolate k on one side of the equation.

First, combine like terms on the left side of the equation. 5k and 2k can be added together.

30+5k+2k=100

30+(5k+2k)=100

30+7k=100

30 is being added to 7k. The inverse of addition is subtraction. Subtract 30 from both sides of the equation.

30-30+7k=100-30

7k= 100-30

7k= 70

k is being multiplied by 7. The inverse of multiplication is division. Divide both sides by 7.

7k/7=70/7

k=70/7

k= 10

The solution to the equation 30+5k+2k=100 is k=10

If R measures 18°,q equals 9.5 ,p equals 6.0 then we can find the length of PQ which is r using the law of cosines.

In trigonometric ratios law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. Law of cosines is as under:

[tex]c^{2} =a^{2} +b^{2} -2ab cos d[/tex]

where c is the side opposite to the angle given, a,b are the other sides and d is the angle given.

We have been given ∠R=18°, q equals 9.5 , p equals 6.0 then the length r can be calculated as under:

[tex]r^{2} =p^{2} +q^{2} -2pq cos 18[/tex]

r=[tex]\sqrt{p^{2} +q^{2} -2pq cos 18}[/tex]

Hence the length of r is equal to [tex]\sqrt{p^{2} +q^{2} -2pq cos 18}[/tex].

Answer:

The decimal point should be placed between 9 and 7

i.e

269.70

Step-by-step explanation:

In Long division method, the formula is given as:

Dividend ÷ Divisor = Quotient

We were given

26.97 ÷ 6.3

26.97 = Dividend

6.3 = Divisor

We are told in the question that:

as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number,

This means, since the Divisor 6.3 is made into an whole number = 63

It means 6.3 was multiplied by 10

6.3 × 10 = 63

In Long division, whatever rule is applied to the Divisor must be applied to the Dividend.

Since 6.3 was multiplied by 10 = 63(whole number), then the dividend must be multiplied by 10

Dividend = 26.97 × 10 = 269.7

Therefore, the place where should the decimal point be placed in the dividend is between 9 and 7

= 269.70

Answer: Between the 9 and the 7

Answer:

(g ○ f)(0) is invalid

Step-by-step explanation:

g(x) = x − 4

f(x) = 1/x

(g ○ f)(x) = 1/x - 4

(g ○ f)(0) can not be evaluated, because if x = 0, 1/x becomes invalid.

Answer:

To evaluate the composition, you need to find the value of function f first. But, f(0) is 1 over 0, and division by 0 is undefined. Therefore, you cannot find the value of the composition.

[tex]13 - 4(x - 5)[/tex]

First of all, the bracket will be solved as per the BODMAS rule.

The bracket term is:

[tex]4(x-5)[/tex]

Now, 4 will be multiplied with [tex]x[/tex] and -5.

i.e.

[tex]4(x-5)=(4\times x-4\times 5)\\\Rightarrow (4x-20)[/tex]

Now, let us put the value back in the original expression.

[tex]13 - 4(x - 5) = 13-(4x-20)[/tex]

Now, let us remove the bracket, negative sign will be multiplied with both i.e. [tex]4x[/tex] and -20

[tex]\Rightarrow 13-4x+20 (\because[/tex] negative multiplied with negative makes positive term)

Now, 13 and 20 are like terms, they will be added.
