Answer:

x - 2

Step-by-step explanation:

Rewrite this symbolically:  "Double a​ number, minus the sum of the number and two"

Let x represent the unknown number.

Then:           2x - (x + 2), or 2x - x - 2, or x - 2

Answer:

Composition:   [tex]f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Domain = { [tex]x\,/\,x\geq \,-4[/tex]  }

Step-by-step explanation:

Given

[tex]f(x)=4\,x-1\,\,\, and \,\,\, h(x)=\sqrt{x+4}[/tex]

The requested composition becomes:

[tex]f(x)\,^o\,h(x)=f(h(x))\\f(x)\,^o\,h(x)=f(\sqrt{x+4} )\\f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]

Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:

[tex]x+4\geq \,0[/tex]  (so the square root is defined in the Real number system)

This means [tex]x\geq \,-4[/tex]

The Domain is then all the Real x-values such that [tex]x\geq \,-4[/tex]

Answer:

[tex]y=4x^2+12x+9[/tex]

Step-by-step explanation:

Perform the square of the binomial, combine like terms, and then write the remaining expression in decreasing order of powers of x:

[tex]y=(2x+3)^2\\y=(2x+3)\,(2x+3)\\y=4x^2+6x+6x+9\\y=4x^2+12x+9[/tex]

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Answer:

Step-by-step explanation:

17 : i 12x^2(4x−3) ,

ii : 5x(x−3y) ,

iii: 5xy^2z(3x^2−5z^2)

18) since the two polynomial are equal then :

2x^3+ax^2+3x-5 = x^3+x^2-2x+a  same remainder x-2 then x=2

2(2)^3+a(2)^2+3(2)-5=(2)^3+(2)^2-2(2)+a     solve for a

-3a=9

a=-3

18 ) x^3+y^3 -125+15xy

       x^3+y^3-(5)^3-3(x)(y)(-5)   then factorize x^3+y^3

       (x+y)(x^2-xy+y^2)- (5)(5)^2-3(x)(y)(-5)   common factor x+y-5

        (x+y-5)(x^2-xy+y^2-5^2-3xy         given x+y=5

          5-5( x^2-xy+y^2-25-3xy) = 0

the value of the expression equal to zero

Answer:

D: 64 x^27 y^125

Step-by-step explanation:

You can use either a calc or your knowledge of cube roots. I will be using knowledge.

You can automatically rule out a and b as if you take the cube root of 12, no whole number comes out. You are left with c and d. Option D is correct because the cube root of 64 is a whole number (4), the cube root of 27 is a whole number (3), and the cube root of 125 is also a whole number(5).

Answer:

30

Step-by-step explanation:

180 = 90 + x + 20 + x + 10

90 = 2x + 30

x = 30

Answer:

Number of child tickets = 9

Number of adult tickets = 36

Number of senior tickets = 27

Step-by-step explanation:

Given:

The ratio of adult tickets to child tickets = 4:1

Ratio of adult  tickets to senior tickets = 4:3

Number of total tickets = 72

Find:

The number of each ticket.

Computation:

Ratio between Adult to senior to child = 4:3:1

So,

Number of child tickets = [1 / (4+3+1)]Total tickets

Number of child tickets = [1 / (8)]72

Number of child tickets = 9

Number of adult tickets = [4 / (4+3+1)]Total tickets

Number of adult tickets = 36

Number of senior tickets = [3 / (4+3+1)]Total tickets

Number of senior tickets = 27

y=(x-5)/3

which can be rewritten as B.

Answer:

c ≅ 35.4 cm.

Step-by-step explanation:

To find the length of the Hypotenuse of a triangle, the formula  a² + b² = c² will need to be used. Therefore:

26² + 24² = c² (c is the hypotenuse)

1252 = c²

√1252 = c

c ≈35.38

Round to tenths place:

c ≅ 35.4 cm. This is the Hypotenuse of the triangle.

Multiply (x)

Step-by-step explanation:

If you multiply 15.5 x 3.90 it will give you the total amount of money Chris and Jeff earned.

Answer:

multiply x

Step-by-step explanation:

If you multiply 15.5 x 3.90 it will give you the total amount of money Chris and Jeff earned.

24 is 2.5 standard deviations away from the mean.

Now it given that,

mean = 18

standard deviation = 4

value = 24

Let x be the standard deviation away from the mean.

Since we know that,

Mean + Standard deviation * x = Value

Therefore putting the value we get,

18 +  4x = 24

Subtracting 18 both the side,

or, 4x = 24 -18

or, 4x = 6

Dividing by 4 both the side we get,

or, x = 6/4

or, x = 2.25

Hence,24 is 2.5 standard deviations away from the mean.

#SPJ2

Answer:

Step-by-step explanation:

First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0

Answer:

x=0

Step-by-step explanation:

4(7-3x)=7(4-2x)

Distribute

28 -12x = 28 -14x

Subtract 28 from each side

-12x = -14x

Add 14x to each side

-12x+14x = -14x+14x

2x=0

x =0

Answer:

5.75 cm²

Step-by-step explanation:

→ Utilise the area of a triangle formula

Area of a triangle = 0.5 × Base × Height

→ Identify base and height in the triangle

Base = 4.6 cm

Height = 2.5 cm

→ Substitute in the values into the area of a triangle formula

Area of a triangle = 0.5 × 4.6 × 2.5

→ Simplify

Area of a triangle = 5.75 cm²

Area of a triangle = 1/2 x base x height

= 1/2 x 4.6 x 2.5

= 5.75 sq. cm
