Answer:

y = (x + 9)² - 83

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = x² + 18x - 2

Obtain vertex form by using the method of completing the square

add/subtract (half the coefficient of the x- term )²

y = x² + 2(9)x + 81 - 81 - 2

  = (x + 9)² - 83

The ANSWER IS Y=(x+9)^2-83

Answer:

d) 12(100) + 12(80) + 12(5)

Step-by-step explanation:

According to the distributive property, if a,b, c, and d are real numbers, then

a(b+c+d)=ab+ac+ad

We want to find the product 12(185).

We can expand 185 as 100+80+5

Our product then becomes;

[tex]12(185)=12(100+80+5)[/tex]

We expand using the distributive property to get;

[tex]12(185)=12(100)+12(80)+12(5)[/tex]

The correct choice is D

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

12(185)

Firstly we can write

185=100+80+5

So, it will be rewritten as

12(100+80+5)

As we know that distributive law that implies

a(b+c+d)=ab+ac+ad

So, according to distributive law, it becomes,

12(100)+12(80)+12(5)

Hence, option 'd' is correct.

Answer:

Figure A - hexagon

Figure B - triangle

Figure C - rectangle

Figure D - octagon

Step-by-step explanation:

If figure B has 3 vertices (angles), then that means it is a triangle (3 sides)

So that means figure A has 6 sides, (hexagon)

And figure D has 8 vertices, so 8 sides (octagon)

And if C has half as many, that would be 4 (rectangle)

ANSWER

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

EXPLANATION

The given function is

[tex]f(x) = {e}^{x} [/tex]

Let

[tex]y={e}^{x} [/tex]

We interchange x and y.

[tex]x={e}^{y} [/tex]

Solve for y.

[tex]y = ln(x) [/tex]

This implies that,

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

The correct answer is C

Answer:

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

Step-by-step explanation:

Given function is [tex]f\left(x\right)=e^x[/tex].

Now we need to find it's inverse so follow these steps:

Step 1: replace f(x) with y.

[tex]y=e^x[/tex]

Step 2: Switch x and y.

[tex]x=e^y[/tex]

Step 3: Solve for y.

[tex]x=e^y[/tex]

[tex]ln(x)=ln(e^y)[/tex]

[tex]ln(x)=y[/tex]

[tex]y=ln(x)[/tex]

Step 4: Replace y with [tex]f^{-1}(x)[/tex].

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

Hence final answer is [tex]f^{-1}(x)=ln(x)[/tex].

CA is a diameter of the circle, so [tex]m\widehat{AC}=180^\circ[/tex], which means [tex]m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ[/tex]. Then [tex]m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ[/tex].

This means [tex]m\angle CBO=55^\circ-35^\circ=20^\circ[/tex]. Also, if [tex]m\angle AOB=55^\circ[/tex], then [tex]m\angle BOC=180^\circ-55^\circ=125^\circ[/tex], which in turns tells us that [tex]m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ[/tex].

Answer: Please Mark Brainliest :) !!

The answer is x= 6 and y= 27.

Step-by-step explanation:

3x + 9 = 5x + 3

-2x + 9 = -3

y = 5x -3

x = 6

y = 5x -3

y = 5(6) -3

y = 27

First, when solving for x, you would need to make one of the equation into standard form, which would be Ax + By = C. So, I'm going to use y = 5x -3.

y = 5x - 3  || subtract -5x on both sides from the equal sign

5x + y = -3  || there you have one equation in standard form

Now, all you have to do now is substitute the y-intercept form equation into the standard form equation. As you can see, you would substitute the y-intercept form into the y in the standard form equation.

5x + y = -3

5x + 3x + 9 = -3  || combine like terms

8x + 9 = -3  || subtract 9 on both sides from the equal sign

8x = 6  || divide by 8 on both sides from the equal sign

x = 0.75  || final answer for x

Then for solving y, take any equation in y-intercept form and substitute with the x in the equation, which I'm going to use y = 3x + 9 in this case.

y = 3x + 9  || substitute with x

y = 3 (0.75) + 9  || multiply 3 and 0.75

y = 3.75 + 9  || add 3.75 and 9

y = 12.75  || final answer for y

Thus, x = 0.75 and y = 12.75.

Answer:

x = -6 or 1

Step-by-step explanation:

x² + 5 x - 6 = 0

Factors = -6 , 1

Sum = 5

Product = -6

x ( x + 6 ) - 1 ( x + 6 ) = 0

( x + 6 ) ( x - 1 )

x + 6 = 0

x = -6

x - 1 = 0

x = 1

Subtract 0.2 by both sides and the your answer is f = -3.2

Answer:

the answer is f=-3.2

Step-by-step explanation:

because with solving linear equations you have to do the opposite of what your doing do like  f+0.2=−3 since your adding you want to subtract instead you want to subtract on both sides so we know 0.2-0.2= 0 so 0.2- -3= -3.2 so that gives us our answer -3.2

Answer:

x=8

Step-by-step explanation:

The two angles are complementary angles, so they add together to make 90 degrees

x+50 + 4x = 90

Combine like terms

5x+50 = 90

Subtract 50 from each side

5x+50-50= 90-50

5x = 40

Divide by 5

5x/ 5 = 40/5

x = 8

Answer:

The function is  [tex]f(x)=2x-1[/tex]

Step-by-step explanation:

If a function has a zero of [tex]\frac{1}{2}[/tex].

The we can write  [tex]x=\frac{1}{2}[/tex].

We need to work backwards to obtain the function:

We multiply through by 2 to get:

[tex]2x=1[/tex].

This implies that:

[tex]2x-1=0[/tex]

Hence a function with such zero is  [tex]f(x)=2x-1[/tex]

Answer:

The function is [tex]f(x)=4x-2[/tex]

Step-by-step explanation:

That a function has a zero at a certain number x means that [tex]f(x)=0[/tex]

Let's see an example,

If we have [tex]f(x)=x+2[/tex] (this is what we call function)

and we choose any value for the x,

x = 3

Now we replace it in our function

[tex]f(3)=3+2[/tex]

[tex]f(3)=5[/tex] (this is the image of 3)

Now if we say that x = -2, and replace it in our function

[tex]f(-2)=(-2)+2[/tex]

[tex]f(-2)=0[/tex] , this means that our function has a zero at x = -2

We can find the zeros of our function equaling it to zero and clearing the x, let's see

[tex]x+2=0[/tex]

[tex]x=-2[/tex]  this means that our function has a zero at x = -2

To find a function that has a zero at  [tex] \frac{1}{2}[/tex] , let's think that the result must be [tex]f(x)=0[/tex]

If we have 4 and multiply it by 1/2.

[tex]4)(\frac{1}{2})=2[/tex], now we subtract 2 from this result

[tex]-2 = 0[/tex] , the complete process would be

[tex]4)(\frac{1}{2})-2=0[/tex], we said that [tex] \frac{1}{2}[/tex], then

[tex]4x-2[/tex], now we write it as a function

[tex]f(x)=4(x)-2[/tex]  we know that by replacing the x by 1/2 the result will be zero, which means that [tex] \frac{1}{2}[/tex] is zero of this function

Answer:

Abraham Lincoln, the 16th president of the United States, was born on February 12, 1809 and died at the age of 56 on the 4th day of March 1861. Lincoln was the president of the United States for four years from 1861 to 1865. Lincoln was born in Hardin County in the state of Kentucky in a small cabin that only had one room. His parents, Thomas Lincoln and Nancy Hanks were farmers who had a large track of land that measured 348 acres on which their cabin was situated. His parents were uneducated, however.

Lincoln’s political career began in 1832 when he created a political campaign for a political party known as the Whig Party. This party was based on efforts that sought to improve navigation on the neighboring river. Ten years later, Lincoln married the love of his life, Mary Todd, with whom he had four sons. Unfortunately, only one of his four sons did not survive into adulthood. Lincoln’s participation in active national politics took a turn for the better in 1842 when he campaigned and was elected to the US House of Representatives.
