Is the equation proportional?
y = 2x + 6

Element and in which every element has a right inverse is a group?

Now, If both the identity and the inverse are of the same side, this is simple. For, instead of the above, say every element has a left inverse. For a∈G denote this left inverse by a−1.

Then(aa−1)(aa−1)=a(a−1a)a−1=aa−1

and we can use the fact that

cc=c

⟹c=1

to get that inverses are in fact two-sided: aa−1=1

From which it follows that

a=1⋅

a=(aa−1)a=a(a−1a)=a⋅

1 as desired. But in the scenario given we cannot use cc=c⟹c=1, and I can see no other way to prove this.

Answer:

78

Step-by-step explanation:

To compute (f.g)(5.5) , first compute g(5.5) , then use that value in f(x) to compute the composite function value

g(5.5) = -12(5.5) - 6 = -66 - 6 = -72

Use this value for x in f(x) = -x + 6

f(g(5.5)) = f(-72) = -(-72) + 6 = 72 + 6 = 78

Answer:

2x + 6 = 10

x = 2

Step-by-step explanation:

2x + 6 = 10

2x = 4

x = 2

The required number is 2 and

a. The equation is 2x + 6 = 10

b. The variable is x = 2

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Let x be the number.

Now according to the given statement,

Six more than twice a number is 2x + 6

and it is 10.

So we can write
2x + 6 = 10

Substracting by 6 to the both side we get,

2x = 4

Dividing the equation by 2 we get

x = 2

Hence,The required number is 2 and

a. The equation is 2x + 6 = 10

b. The variable is x = 2

One solution; x = 11, y = 8

Step-by-step explanation:

Step-by-step explanation:

so

formula is ( y 1 − y = m ( x 1 − x))

m is the slope

-1-y=2(3-x)

add 1 to both sides

−y−1+1=−2x+6+1

−y=−2x+7

divide both sides by -1

Converting the book's cover area from 72.5 square krylls to square blims is 0.051785 square blims.

The conversion rate refers to the rate of change of a unit of measurement to another unit.

For example, the conversion rate for 100 centimeters equals 1 meter.

To convert the higher unit to a smaller unit, we divide.

Given that 1400 kryll = 1 blim

Area of the book's cover = 72.5 square krylls

The area in square blims = 0.051785 square blims (72.5/1,400).

Thus, the converted area of the book's cover from 72.5 square krylls to square blims is 0.051785 square blims.

According to the given statement

The vertex of the function y = |x + 1| + 3 is (-1,3).

The range of the function y = |x + 1| + 3 is [3,∞)

A function that wraps an algebraic expression in absolute value symbols is known as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value.

The vertex of the function y = |x + 1| + 3

The function is given as:

y = |x + 1| + 3

The above function is an absolute value function

An absolute value function is represented as:

f(x) = a |x – h| + k

Where, the vertex is (h ,k)

So, we have:

(h ,k) = (-1,3)

Hence, the vertex of the function y = |x + 1| + 3 is (-1,3).

The range of the function y = |x + 1| + 3 is [3,∞)

excuse me friend, for you to get the next pattern, you have to know what has been done from this number to the other number.

so from 3 to 6 it was a + 3 from 6 to 11 it was a+5 from 11 to 18 it was a + 7.

if you look carefully,2,3 and 7 are odd numbers meaning that the next pattern should be an odd number (9) which will be added to the numbers at the top.

you can still say that they were increasing by 2. (3 to 5 to 7)

so you can add 2 to 7 to get a nine. then,add 9 to 18 to get a 27.

Function transformation involves changing the form of a function.

The equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

The parent function is given as:

[tex]f(x) = \sqrt[3]{x}[/tex]

First, the function is shifted left by 6 units.

The rule of this translation is:

[tex](x,y) \to (x + 6,y)[/tex]

So, we have:

[tex]f(x) = \sqrt[3]{x + 6}[/tex]

Next, the function is shifted up by 1 unit.

The rule of this translation is:

[tex](x,y) \to (x,y+1)[/tex]

So, we have:

[tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

Hence, the equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

Answer:

yes

Step-by-step explanation:

1) On average, the time Jamie cut off her mile each month is 6.5 seconds.

2) In this context, the 6.5 seconds that Jamie cut off her mile each month means that she can finish a 9-minute-mile race by less than 6.5 seconds.

The average cut-off time per month is determined by the mathematical operation of division.

Average refers to the mean of a data set divided by the number in the data set.

The race Jamie is training for = a 9-minute mile

Cut-off time achieved in 6 months = 39 seconds

Period of training = 6 months

Average cut-off time = 6.5 seconds (39/6)

Time Jamie can finish the race = 8 minutes and 53.5 seconds (9 minutes - 6.5 seconds)

Thus, Jamie can complete the race in 8 minutes and 53.5 seconds if she maintains the average.
