From the inequality given by 8x + 15 > 9x - 26, x is less than 41.

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

Solving the inequality,

8x + 15 > 9x - 26

Combine like terms in one side and the constants in the other side.

8x - 9x > -26 - 15

-x > -41

Divide both sides by -1.

x > 41

Note that when we multiply or divide by a negative number

we must reverse the inequality.

x < 41

Answer:

= 0.25m/s

Step-by-step explanation:

The formula of finding the speed, v is given by

[tex]v \: = \frac{change \: in \: distance \: d}{change \: in \: time \: t} [/tex]

The change in distance from the graph is

∆d = (8 - 6)

= 2 m

The change in time from the graph is

∆d = (20 - 12)

= 8s

Substituting to our formula, we have

[tex]v \: = \frac{2m}{8s} \\ = \frac{1}{4} \frac{m}{s} \\ = 0.25 {m}s^{ -1 } [/tex]

Therefore, the speed v, of the journey between 12 and 20 second is 0.25m/s.

The dimensions are 3 inches, 10 inches, and 13 inches.

It should be noted that the diagonal is the longest side. This will be solved by using Pythagoras theorem.

Therefore,

(2x + 6)²

4x²+ 24x + 36

Reduce to lowest term

x² + 6x + 9

x² + 3x + 3x + 9

x(x + 3) - 3(x + 3)

(x - 3) = 0

x = 0 + 3 = 3

Therefore x = 3

Therefore the dimensions will be:

Answer:

The value of x is 12 if the value of f^-1(x) = 2.

Step-by-step explanation:

It is given that f(x) = 4(x + 1), which is an inverse function.

Now,

First of all, let us understand what is a function and an inverse function;

A function in mathematics from a set X to a set Y allocates precisely one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

On the other hand;

A function that may reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

Now, let us consider the first part of the question;

We have to calculate the value of x when f^-1(x) = 2 given that f(x) = 4(x+1) is the function;

=> f(x) = 4(x + 1)

=> 4(y + 1) = x

=> x = 4y + 4

=> y = (x - 4)/4

=> f^-1(x) = (x - 4)/4

Hence, f^-1(x) = (x - 4)/4 is the inverse of f(x).

Now, let us put the value of f^-1(x) = 2 in the equation so obtained;

=> f^-1(x) = (x - 4)/4  

=> 2 = (x - 4)/4

=> 8 = (x - 4)

=> x = 12

Hence, the value of x is 12 if the value of f^-1(x) = 2.

The percentage is the hundredth of any digit or value between 1 to 100 so 35% of 900 will be 315.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The x percentage of any random y digit is given as;

⇒ (x/100) × y

Therefore,

35% of 900 →

(35/100) × 900

⇒ 35 × (900/100)

⇒ 35 × 9

⇒ 315

Hence " The 35% percentage of the amount 900 will be 315".

Answer:

.67 (See explanation for why)

Step-by-step explanation:

2/3

in order to turn this into a whole number, we are going to multiply the bottom number until it becomes any number starting with 1 and ending with a zero. this isnt possible Because 3 is a number that cannot do that.

So instead, we will multiply the number by 333

2*333 = 666

3*333 = 999

666/999 = 2/3

999 is nearly 1000, so lets write the decimal point 3 spaces inwards

.666

which can become

The longer decimal for this(when using a calculator)

would give you

And if we round,

7 is higher than 5, so it becomes .666666667

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

For any generic amounts a and b, to find how much an amount a is more than an amount b, we subtract a by b.

For this problem, the budgets are given as follows:

Hence the difference is given by:

2.6 x 10¹¹ - 2.47 x 10^9

To subtract two numbers in scientific notation, they must have the same exponent, hence:

2.47 x 10^9 = 0.247 x 10^10 = 0.0247 x 10¹¹.

Then the difference is:

2.6 x 10¹¹ - 0.0247 x 10¹¹ = 2.5753 x 10¹¹ (to subtract two numbers in scientific notation, we subtract the bases and keep the exponents).
