Answer:

25 x 13 = 325

Step-by-step explanation:

Answer:

Perpendicular lines have opposite reciprocal slopes, so the slope of the line is -.5

Now, y=.5x+b, so you plug in the point -2,6.

6=.5(-2)+b

6=-1+b, so b=7.

The equation is y= .5x+7

Answer:

  rational

Step-by-step explanation:

Any number that can be written with a finite number of digits is rational. The given number is rational. (It has 5 digits.)

__

Any repeating decimal is rational.

If this were -9.2222..., it would be -9 2/9 = -83/9, also a rational number.

_____

A number is irrational if it cannot be represented exactly as a decimal or repeating decimal. That is, its decimal fraction part continues forever without repeating.

Answer:

x = 0

Step-by-step explanation:

7x-3(x-1)=(2x+3)

7x - 3x + 3 = 2x + 3

4x + 3 = 2x + 3

2x = 0

x = 0

Answer:

x > -1

Step-by-step explanation:

Isolate the variable, x. Treat the > sign like an equal sign, what you do to one side, you do to the other.

Subtract 5 from both sides:

x + 5 (-5) > 4 (-5)

x > 4 - 5

x > -1

x > -1 is your answer.

~

Answer:

x > -1

Step-by-step explanation:

Step 1: Write inequality

x + 5 > 4

Step 2: Solve for x

Here we see that any value x that is greater than -1 will work.

Answer:

y = 3/4x + 1/2

Step-by-step explanation:

We can use the formula [ y2-y1/x2-x1 ] to solve for the slope.

-4-5/-6-6

-9/-12

9/12

3/4

Find the y-intercept.

y = 3/4x + b

5 = 3/4(6) + b

5 = 4.5 + b

0.5 = b

y = 3/4x + 1/2

Best of Luck!

First of all, Let's find the slope because we need it on the formula for finding the y-intercept.

From the points given in the question,

Plugging in the above formula,

➝ m = -4 - 5 / -6 - 6

➝ m = -9 / -12

➝ m = 3/4

Now finding the y-intercept[tex]:[/tex]

➝ y = mx + b

And if we put in the values from our first point (6, 5) we get

➝ 5 = 3/4 (6) + b

➝ 5 = 9/2 + b

➝ b = 5 - 9/2

➝ b = 1/2

Required equation of the line:

➝ y = 3/4x + 1/2

Answer:

[tex]\sqrt[5]{25x^{2}y^{4}z^{6} }[/tex]

Step-by-step explanation:

going to the 2/5 power is the the fifth root of a square. For fraction exponents going into radical form use the denominator as you root of and use the numerator as the exponent of the rest making sure to multiply any other exponents by that number and when there is no exponent treat it as having an exponent of one for the multiplying.  

Answer:

x = - 2, - 3

Step-by-step explanation:

Given

- 3x + 4 ≥ 9 ( subtract 4 from both sides )

- 3x ≥ 5  

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.

x ≤ - [tex]\frac{5}{3}[/tex]

The only values of x that satisfy the inequality in the interval { - 3, 3 } are

x = - 2, x = - 3

Let's see what to do buddy...

________________________________

If 99 & 100 are in Degree

_________________________________

STEP (1)

The angles 99 and 100 are in the second quarter of the trigonometric circle.

The cosine is negative in the second quarter.

To make things easier, we can use angle conversion.

Look :

[tex]we \: know \: that \: 100 = 90 + 10[/tex]

[tex]also \: we \: know \: 99 = 90 + 9[/tex]

So :

[tex] \cos(100) = \cos(90 + 10) = \cos( \frac{\pi}{2} + 10 ) \\ [/tex]

[tex] \cos(99) = \cos(90 + 9) = \cos( \frac{\pi}{2} + 9 ) \\ [/tex]

_________________________________

STEP (2)

Well now we have to do the arc deletion.

To remove the arc, we remove π/2 from the arc.

Remember that every time we remove π/2 from the arc, the trigonometric ratio changes.

That is, if it is a sine, it becomes a cosine, and if it is a cosine, it becomes a sine.

Or if it is a tangent, it becomes a cotangent, and if it is a cotangent, it becomes a tangent.

[tex]in \: second \: quarter \: cosine \: is \: negative \\ \\ \cos( \frac{\pi}{2} + 10 ) = - \sin(10) = - 0.173 [/tex]

[tex] \cos( \frac{\pi}{2} + 9 ) = - \sin(9) = - 0.156 \\ [/tex]

_________________________________

STEP (3)

[tex] \cos(100) - \cos(99) = \\ - \sin(10) - ( - \sin(9) \: ) = \\ - 0.173 - ( - 0.156) = \\ - 0.173 + 0.156 = - 0.017 [/tex]

And we're done here.

_________________________________

If 99 & 100 are in Radian

_________________________________

STEP (1)

First we need to know how many degrees 1 radian is.

The following equation is used to convert degrees to radians or radians to degrees.

[tex] \frac{degree}{180} = \frac{radian}{\pi} \\ [/tex]

So we have :

[tex] \frac{d}{180} = \frac{1}{\pi} \\ [/tex]

Multiply the sides of the equation by 180 :

[tex]d = \frac{180}{\pi} = \frac{180}{3.14} = 57.32 \\ [/tex]

So 1 radian is approximately equal to 57 degrees.

And we have :

[tex]100 \: rad \: = 100 \times 57 = 5700 \: deg \\ \\ 99 \: rad \: = 99 \times 57 = 5601 \: deg[/tex]

_________________________________

STEP (2)

Let's move on to deletion.

Look : 5700° = 15 × 360° + 300°

and : 5601° = 15 × 360° + 201°

We know π rad = 3.14 × 57 = 180° deg

So 2π rad = 2 × 180 = 360 ° deg

Then :5700 = 15 × 2 π + 300° = 30 π + 300°

and :5601 = 15 × 2 π + 201° = 30 π + 201°

Remember that deleting 2π is unconditional.

[tex] \cos(30\pi + 300) = \cos(300) = \cos(360 - 60) = \cos(2\pi - 60) = \cos( - 60) = \\ cosine \: eat \: negative \\ \cos( - 60) = \cos(60) = \frac{1}{2} [/tex]

[tex] \cos(30\pi + 201) = \cos(201) = \\ \cos(180 + 21) = \cos(\pi + 21) = \\ - \cos(21) = - 0.933 [/tex]

[tex] \frac{1}{2} - ( - 0.933) = 0.500 + 0.933 = 1.433[/tex]

And we're done.

Thanks for watching buddy good luck.

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

Explanation:

In any quadrilateral, the four angles always add to 360

P+Q+R+S = 360

x+5x+x+5x = 360

12x = 360

x = 360/12

x = 30

This means

P = R = x = 30

Q = S = 5x = 5*30 = 150

So, P+Q+R+S = 30+150+30+150 = 360 which helps confirm the answer.

Answer:

x = 30

Step-by-step explanation:

the sum of all angles is 360

the picture shows that the sum equals 12x

12x=360

x= 360/12

x = 30

Step-by-step explanation:

If you add negitives you get a negitive and a plus a positive you get positive positives are bigger than negitives  

[tex]g( \: f(x) \: ) = x[/tex]

And

[tex]f( \: g(x) \: ) = x[/tex]_________________________________

So :

[tex]g(x) = {f}^{ - 1}(x) [/tex]

And

[tex]f(x) = {g}^{ - 1}(x) [/tex]

_________________________________

So to find g(x) , we must find the inverse of f(x) .

Let's do it .....

[tex]f(x) = 8 {x}^{3} + 1 [/tex]

[tex]y = 8 {x}^{3} + 1 [/tex]

Subtract the sides of the equation minus 1

[tex]y - 1 = 8 {x}^{3} [/tex]

Divided the sides of the equation by 8

[tex] \frac{y - 1}{8} = {x}^{3} \\ [/tex]

From the sides of the equation, we take the radical with interval 3

[tex] \sqrt[3]{ \frac{y - 1}{8} } = x \\ [/tex]

[tex] \sqrt[3]{ \frac{1}{8}(y - 1) } = x \\ [/tex]

[tex] \frac{1}{2} \sqrt[3]{y - 1} = x \\ [/tex]

[tex] \frac{ \sqrt[3]{y - 1} }{2} = x \\ [/tex]

So ;

[tex] {f}^{ - 1}(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]

Now we find g(x) which is :

[tex]g(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]

_________________________________

And we're done.

♥️♥️♥️♥️♥️

If f(g(x)) = x and g(f(x)) = x , than  [tex]\rm g(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex] and this can be calculated by finding the inverse of the given function f(x).

Given :

Given that f(g(x)) = x it means that:

[tex]\rm g(x) = f^{-1}(x)[/tex]

It is also given that g(f(x)) = x that means:

[tex]\rm f(x) = g^{-1}(x)[/tex]

Now, the inverse of f(x) is given by the following calculation:

[tex]\rm f(x) = 8x^3+1[/tex]

Now, replace f(x) with y in the above equation.

[tex]y = 8x^3+1[/tex]

Now, replace y with x and x with y and evaluate 'y'.

[tex]x = 8y^3 +1[/tex]

[tex]\sqrt[3]{\dfrac{x-1}{8}}=y[/tex]

Now, replace y with [tex]\rm f^{-1}(x)[/tex] in the above equation.

[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex]

[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}} = g(x)[/tex]

Answer:

X=3

Step-by-step explanation:

You'd use the distributive property and multiply everything in the parentheses by 3.

So you'd end up with 6x-12= 6  

then add 12 to both sides so you now have 6x= 18

from here you divide 6x from 18 and that equals 3
