Answer:

b = 1/3

Step-by-step explanation:

6(b+1)=8

Solving for b

Distribute

6b +6 = 8

Subtract 6 from each side

6b+6-6 = 8-6

6b = 2

Divide by 6

6b/6 = 2/6

b = 1/3

Answer:  C. Function composition

Step-by-step explanation:

If we have two functions, we can form a new function by composing one function into the other.  Such functions are known as composite functions.

For example we have two functions f and g and produces a function h such that h(x) = g(f(x)).  

It is generally a function that is written inside another function.

i.e. it is a process of using the output of one function as the input for another.

Thus, the correct option is  C.

The required term:  Function composition

Step-by-step explanation:

adjacent side:

using Pythagoras

hypo² = oppo² + adja²

(√13)² = 2² + adja²

adja²= 13 -4

adja²=9

adjacent side = 3

so tan A= oppo/adja

tan A=2/3

Answer:0 = 3x - 21

Step-by-step explanation:

From this given function we can take an  

x

common from its expression

i.e  

x

2

−

6

x

=

x

(

x

−

6

)

As we know that the product of two numbers is zero,when either one of them is zero

then in the above expression that we just factorised

the function can be zero when either  

x

=

0

or when  

x

=

6

i.e when  

x

=

0

,  

0

(

0

−

6

)

=

0

when  

x

=

6

,  

6

(

6

−

6

)

=

6

(

0

)

Finally, our prize of all that math, the zeroes of the function are  

0

and  

6

these numbers are called the zeroes of the function because when you put these values in  

x

the function gives zero.

One solution, the answer is x = 0.

Given:

Angelica reads 15 pages of a book each day.

In 10 days, she reads 200 pages.

Assume the relationship is linear.

To find:

The rate of change and initial value.

Solution:

The slope intercept form of a linear function is:

[tex]y=mx+b[/tex]            ...(i)

Where m is the slope and b is the y-intercept.

Angelica reads 15 pages of a book each day. So, the rate of change is 15 pages per day and [tex]m=15[/tex].

In 10 days, she reads 200 pages. It means the linear relation passes through the point (10,200).

Putting [tex]x=10,y=200,m=15[/tex] in (i), we get

[tex]200=15(10)+b[/tex]

[tex]200=150+b[/tex]

[tex]200-150=b[/tex]

[tex]50=b[/tex]

So, the y-intercept is 50. It means the initial number of pages angelica already read is 50.

Therefore, the rate of change is 15, it means Angelica reads 15 pages per day. The y-intercept is 50, it means the initial number of pages angelica already read is 50.

Step-by-step explanation: The multiplicative inverse is the reciprocal of the number

Answer:

8 cm and 9 cm by using a>b+c where a, b and c are sides of a triangle

===================================================

Work Shown:

a^2+b^2 = c^2

15^2+20^2 = 25^2

225+400 = 625

625 = 625

Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.

Side note: c is always the longest side.

Answer:

Hello There!!

Step-by-step explanation:

I believe the answer is 21:14. Split 104 minutes so it will be easier to calculate so it's 60 and 44. 60 minutes is 1 hour so add 1 hour to 19:30 which is 20:30 then there is 44 minutes left. There is 30 minutes left to make it 21:00 so there is 14 minutes left at the end and add that to 21:00 which is 21:14.

hope this helps,have a great day!!

If a film starts at 19:30 and lasts 104 minutes.

The film will end at 21:14.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. 

Example:

x + y + 2 is an expression.

We have,

Film start time = 19:30

Duration of the film = 104 minutes

1 hour = 60 minutes

Multiply 104/60 on both sides

104/60 x 1 hour = 104/60 x 60 minutes

1.73 hours = 104 minutes

The time the film will end:

= 19:30 + 1.73 hours

= 19:30 + 1 hour + 44 minutes

= 21:14

Thus,

The film will end at 21:14.

Answer:

1 real and 2 complex

Step-by-step explanation:

The Fundamental theorem of Algebra states that a polynomial of degree n has n zeros, some may be complex.

A cubic is a polynomial of degree 3 , then has 3 zeros.

From the graph

There is a real zero at x = 4

Thus the other 2 must be complex

Answer:

Kaylia = $48,000

Kaylia = $48,000

Keisha = $12,000

Step-by-step explanation:

Karen = 5

Kaylia = 8

Keisha = 2

Total ratio = 5 + 8 + 2

= 15

Estate value = $90 000

Karen = 5/15 × $90 000

= 1/3 × $90 000

= $90 000 / 3

= $30,000

Karen = $30,000

Kaylia = 8/15 × $90,000

= (8 * 90,000) / 15

= 720,000/15

= $48,000

Kaylia = $48,000

Keisha = 2/15 × $90,000

= 180,000/15

= $12,000

Keisha = $12,000
