Step-by-step explanation:

110 - 25 divided by 2 because

angle ABC = (angle AC- angle DE)÷2

First plug in g(x) into f(x)

F((g(x))=2(2x+3)

And now you plug in -8

F(g(-8))=2(-16+3)

F(g(-8))=2(-13)

F(g(-8))=-26

Answer:

The correct answer is option A. 18x + 15

Step-by-step explanation:

It is given an expression in variable x,

5(4x + 3) - 2x

To simplify the given expression

5(4x + 3) - 2x = (5 * 4x) + (5 * 3) - 2x   (open the bracket)

  = 20x + 15 - 2x

  = 20x - 2x + 15

  = 18x + 15

Therefore the correct answer is 18x + 15

The correct option is option A.  18x + 15

Answer:

option b

1 , 16, 121 , 13456

Step-by-step explanation:

Given in the question a function, f(x) = (x - 5)²

initial value [tex]x_{0}[/tex] = 4

First iteration

f(x0) = f(4) = (4 - 5)² = (-1)² = 1

x1 = 1

Second iteration

f(x1) = f(1) = (1 - 5)² = (-4)² = 16

x2 = 16

Third iteration

f(x2) = f(16) = ( 16 - 5)² = (11)² = 121

x3 = 121

Fourth iteration

f(x3) = f(121) = (121 - 5)² = (116)² = 13456

x4 = 13456

Answer:

Write 2x as a difference

Factor out x from the expression

Factor out -2 from the expression

Factor out x + 4 from the expression

Reduce the fraction with x - 2

Answer:

 x + 6

-----------      for all x EXCEPT x = -6

  x + 2

Step-by-step explanation:

Note that the numerator, x^2 + 12 x + 36, factors into (x + 6)^2, and that

the denominator factors into (x + 6)(x - 2).

Thus, the given expression reduces to:

  (x + 6)(x + 6)

-----------------------

  (x + 6)(x + 2)

and can be reduced to:

 x + 6

-----------         This is true for all x EXCEPT x = -6.  At x = -6, the expression

There are total 11 packets of squash seeds and 7 packets of basil seeds.

A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.

According to the given question.

Cost of one packet of basil seeds = $1.50

Cost of one packet of squash seeds = $2.50

Cost of 18 packets of seeds = 38

Also, b represents the number of packets of basil seeds and s represents of numbers of squash seeds.

Therefore, from the given conditions we get some system of equations

[tex]s + b = 18..(i)[/tex]

and [tex]b(1.50) + s(2.50) = 38...(ii)[/tex]

From equation (i)

[tex]s = 18-b[/tex]

Substitute the value of s in the equation (ii)

⇒[tex]1.50b+(18-b)2.50 =38[/tex]

⇒ [tex]1.50b + 45 - 2.50b = 38[/tex]

⇒[tex]-b = 38-45[/tex]

⇒ [tex]-1b =- 7[/tex]

⇒[tex]b = 7[/tex]

So, [tex]s = 18 - 7 =11[/tex]

Hence, there are total 11 packets of squash seeds and 7 packets of basil seeds.

Answer:

Center: (-9, -2)

Radius = 6

Step-by-step explanation:

The general equation of the circle is:

[tex]x^{2} + y^{2}+2gx+2fy+c=0[/tex]

The center of the circle is given as (-g, -f) and the radius of this circle is calculated as:

[tex]r=\sqrt{g^{2}+f^{2}-c}[/tex]

The given equation is:

[tex]x^{2} +y^{2}+18x+4y+49=0[/tex]

Re-writing this equation in a form similar to general form:

[tex]x^{2} +y^{2}+2(9)(x)+2(2)(y)+49=0[/tex]

Comparing this equation with general equation we get:

g = 9

f = 2

c = 49

Thus center of the given circle is (-g, -f) = (-9, -2)

The radius of the circle will be:

[tex]r=\sqrt{9^{2}+2^{2}-49}=6[/tex]

Thus the radius of the given circle is 6.

Answer:

D and E

Step-by-step explanation:

2 and 3 are verticle angles

1 and 4 add up to more than 180

angles 1 2 and 3 add up to more than 180

Based on the figure, the statements are true include;

D. m∠3 ≅ m∠4 = m∠1 ≅ m∠2

E. m∠1 ≅ m∠4 are vertical angles.

In Mathematics and Euclidean Geometry, the vertical angles theorem states that two (2) opposite vertical angles that are formed whenever two lines intersect each other are always congruent, which means being equal to each other.

By applying the vertical angles theorem to the lines, we have the following congruent angles:

m∠1 ≅ m∠4

m∠2 ≅ m∠3

Based on linear pair theorem, we have the following supplementary angles;

m∠3 + m∠4 = 180°

m∠1 + m∠2 = 180°

m∠3 ≅ m∠4 = m∠1 ≅ m∠2 (transitive property).

Answer:

The answer is D. 51,200

Step-by-step explanation:

64000/x=100/80

(64000/x)*x=(100/80)*x       - we multiply both sides of the equation by x

64000=1.25*x       - we divide both sides of the equation by (1.25) to get x

64000/1.25=x

51200=x

x=51200

The number of people who were supporters of the home team is 51,200, the correct answer is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

The home team= 80%

Visiting team= 20%

Now,

If 80% of the people attending the football game were supporters of the home team, then we can find the number of people who were supporters of the home team by multiplying the total number of people attending the game by 80%:

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Given

6x² + x - 1 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 1 = - 6 and sum = + 1

The factors are + 3 and - 2

Use these factors to split the x- term

6x² + 3x - 2x - 1 = 0 ( factor the first/second and third/fourth terms )

3x(2x + 1) - 1(2x + 1) = 0 ← factor out (2x + 1) from each term

(2x + 1)(3x - 1) = 0

Equate each factor to zero and solve for x

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]

3x - 1 = 0 ⇒ 3x = 1 ⇒ x = [tex]\frac{1}{3}[/tex]

Answer:

The radius of circle is 5 cm

Step-by-step explanation:

Given a right triangle △ABC with right angle C is inscribed in a circle in which

m∠C = 90°, AC = 8 cm, BC = 6 cm

we have to find the radius of circle.

As ACB is right angles triangle where angle C is right angle.

⇒ side AB must be the diameter of circle as angle made at semi circle is 90°

[tex]Radius=AO=\frac{1}{2}AB[/tex]

By Pythagoras theorem

[tex]AB^2=AC^2+CB^2[/tex]

[tex]AB^2=8^2+6^2=64+36=100[/tex]

[tex]AB=10cm[/tex]

[tex]Radius=AO=\frac{1}{2}AB=\frac{1}{2}\times 10=5cm[/tex]

Hence, the radius of circle is 5 cm

Answer:

Step-by-step explanation:

Triangles ADB and CDB are similar. Therefore similar parts can form a proportion.

AD/DB = DB/DC

AD = ?

DB = 4

DC = 6

x/4 = 4/6    Cross multiply

6x = 16

6x/6 = 16/6

x = 2 4/6 or x = 2 2/3

It's B

ANSWER

[tex]AD =2 \frac{2}{3}[/tex]

EXPLANATION

According the Altitude Theorem, the height of the triangle is equal to the geometric mean of the two segment it creates on the hypotenuse.

This implies that:

[tex]16 = 6 AD[/tex]

Divide both sides by 6.

[tex]AD = \frac{16}{6} [/tex]

Answer:

35 in²

Step-by-step explanation:

The irregular shaped can be divided into two squares and one rectangle, so the area will be the additions of the area of the squares and the rectangle

area of square A = L *B = 3 *3 = 9in²

area of square B = L * B = 4*4 = 16in²

area of rectangle C = L * B = 5 *2 = 10in²

th area of the irregular shape = 9 in² + 16 in² + 10 in² = 35 in²

Answer: x=7

The solution of the given linear equation in one variable is x = 7.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.

Given is a linear equation in one variable, 2x+6 = 20,

We need to find its solution,

Since, the given linear equation has only one variable, so it will have only one solution.

The equation is =

2x+6 = 20

Solving for x,

2x = 20-6

2x = 14

x = 7

Hence, the solution of the given linear equation in one variable is x = 7.
