Find the value of X in the picture.

Answer:

[tex]\frac{y + 6}{6(y - 1)} [/tex]

Step-by-step explanation:

The given expression is

[tex] \frac{ {y}^{2} + 7y + 6}{6 {y}^{2} - 6} [/tex]

The numerator is a quadratic trinomial and the denominator is different of two squares when 6 is factored.

We factor both the numerator and the denominator to obtain;

[tex] \frac{ (y + 6)(y + 1) }{6(y - 1)(y + 1)} [/tex]

Cancel out the common factors to get:

[tex] \frac{y + 6}{6(y - 1)} [/tex]

This is the simplest form since, we cannot simplify this further.

For this case we must simplify the following expression:

[tex]\frac {y ^ 2 + 7y + 6} {6y ^ 2-6}[/tex]

We factor the numerator, looking for two numbers that when multiplied by 6 and when added together give 7. These numbers are +6 and +1.

Then, rewriting the expression:

[tex]\frac {(y + 6) (y + 1)} {6 (y ^ 2-1)} =[/tex]

We rewrite the denominator:

[tex]\frac {(y + 6) (y + 1)} {6 (y + 1) (y-1)} =[/tex]

We simplify similar terms:

[tex]\frac {(y + 6)} {6 (y-1)}[/tex]

Answer:

[tex]\frac {(y + 6)} {6 (y-1)}[/tex]

【Look at the image】

Answer:

option D

Step-by-step explanation:

[tex]y+2>-3x - 3[/tex]

Subtract 2 from both sides and solve for y

[tex]y>-3x - 5[/tex]

Now graph it using a table

Replace > symbol by == sign

[tex]y=-3x - 5[/tex]

make a table

x        y=-3x-5

0        -5

-1         -2

-2        1

Graph the points (0,-5) and (-2,1)

WE have only > symbol so we use dotted line

For shading we use test point (0,0)

[tex]y>-3x - 5[/tex]

Plug in 0 for x and 0 for y

[tex]0>-3(0) - 5[/tex]

0>-5  True

So we shade the region that contains (0,0)

option D is correct

The axis of symmetry of the parabola [tex]y = -3x^2 + 3x - 13[/tex] is x = 1/2.

The axis of symmetry of a parabola in the form [tex]y = ax^2 + bx + c[/tex] is given by the formula x = -b/2a.

In the given equation [tex]y = -3x^2 + 3x - 13[/tex],

we can identify a = -3, b = 3, and c = -13.

The axis of symmetry is then calculated as x = -b/2a:

x = -3/(2*-3) = -3/-6 = 1/2

So, the correct answer is a. x = 1/2.

Answer: -2

Step-by-step explanation: Find the slope of between the two points. P is the bottom point and Q is the top point. Both x and y numbers increase, meaning that the slope is positive. The x numbers increase by 6, and the y numbers increase by 12. This means that the rise is 12, and the run is 6. The slope is 12/6 but can be simplified to 2/1. The perpendicular slope is -1/2 because the perpendicular slope of a line is opposite reciprocal. This means to make the number negative and to flip it.

Answer:

-1/2

Step-by-step explanation:

So we are asked to find the slope of a line perpendicular to the line going through Q(-6,10) and P(-12,-2).

To do this we first need to find the slope of the line going through Q(-6,10) and P(-12,-2).

We can use the slope formula for a line given two points on that line which is (y2-y1)/(x2-x1).

I like to do something I consider easier to remember and is the same thing

It is:

A) line up the points

B) subtract vertically

C) put 2nd difference over first difference

D) done unless it needs reducing

So that is exactly what I'm going to do here:

(-6, 10)

-(-12,-2)

------------

6 12

So the slope is 12/6 or 2.

Now you might prefer to write 2 as a fraction now, because I'm about to tell you to find the slope of a line that is perpendicular, you just need to take the opposite reciprocal.

Opposite means to change the sign. I'm referring to negative or positive sign.

Reciprocal means to flip the number.

Let's put 2 through that process.

Opposite of 2: -2

Reciprocal of the opposite: -1/2

I got that reciprocal there by realizing -2 is just -2/1.

Anyways the slope of a line that is perpendicular to the one that goes through P and Q is -1/2 or -0.5.

Step-by-step explanation:

This is an absolute value equation.

Firstly we will remove absolute value:

Absolute value always gives the positive result. Hence to remove the absolute value we will take both positive and negative:

|x+4|=2

x+4=2

Move the constant value to the R.H.S

x=2-4

x= -2

x+4 = -2

Move 4 to the R.H.S

x= -2 -4

x= -6

Therefore x = (-2, -6)....

Answer:

Our solutions are x= -7 , x=6

Step-by-step explanation:

x²+x-30=12

First we calculate the constants:

x²+x-30-12=0

x²+x-42=0

Now split the middle term:

x²+7x-6x-42=0

x(x+7)-6(x+7)=0

(x+7)(x-6)=0

As we know that:

a.b=0

⇒either a=0 or b=0

(x+7)=0 , (x-6)=0

x=0-7 , x=0+6

x= -7 , x=6

So our solutions are x= -7 , x=6....

Answer:

x - 4y = 8

Step-by-step explanation:

We are given point slope form of the equation of the line that passes through the point [tex](-4, -3)[/tex] and [tex](12,1)[/tex] which is [tex]y-1=\frac{1}{4} (x-12)[/tex].

We are to write this equation in its standard form.

From the given equation, we know that the slope is [tex]\frac{1}{4}[/tex] so we will find the y intercept.

[tex]y=mx+c[/tex]

[tex]1=\frac{1}{4}\times (12) +c[/tex]

[tex]c=-2[/tex]

Substituting the given values and the y intercept in the standard form of equation.

[tex]y=mx+c[/tex]

[tex]y=\frac{1}{4} x-2[/tex]

Rearranging this to get:

x - 4y = 8

Answer:

x - 4y = 8.

Step-by-step explanation:

y - 1 = 1/4(x - 12)

y = 1/4x - 3 + 1

y = 1/4x - 2

1/4x - y - 2 = 0

1/4x - y = 2

Multiply through by 4:

x - 4y = 8 is standard form.

A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points. A real world example would be a scatter plot of the number if balloons bought each year and a straight line going diagonally representing the average or goal of the number of balloons bought. The points may be above (signaling that the number of balloons purchased was higher than normal or exceeded the goal) or they may be below (signaling that balloon sales are lower than normal or didnt meet there goals). I hope this helps, if not then I apologize

Answer with explanation:

Line of best fit is the line which describes the relationship between two variables with the help of Linear Equation in two variables.

 The equation of line of best fit is:

   y= a x + b

Where, y and x are related with each other,that is with increase in one other may decrease or with decrease in one other may increase or Both increases in same way.

Real life Example

There are ten bulbs which have to be arranged in a rectangular room.Switch off all the Bulbs.Now you have to arrange the bulbs in the room in such a way that room has maximum intensity of light.

As ceiling of room is like two dimensional coordinate plane.Now you have arranged the bulb.You have to draw a line which is called line of best fit such that as the number of bulbs increases intensity of room increases.The line of best fit may pass all the points where bulb is located  or none of the points where bulb is located or may be single or two or three or more than these points where bulb is located.

wait is the kilometers number 412 or 41.2?

The mixed fraction 4 1/2 can be converted to the improper fraction 9/2 by multiplying the whole number by the denominator and then adding the numerator.

The question is asking you to convert a mixed fraction (4 1/2) into an improper fraction. In your case of 4 1/2, an improper fraction is a fraction where the numerator (the top number) is greater than the denominator (the bottom number). To convert a mixed number into an improper fraction, you multiply the whole number (4) by the denominator of the fractional part (2) and add the numerator of the fractional part (1). This gives you the numerator of the improper fraction.

Here's how you do it: 4*2 = 8, then add 1, which gives you 9. Your improper fraction is thus 9/2.

Answer:

The mathematical expression is : (15 - 4) x (14 - 6) square feet.

The evaluation of this expression gives 88 sq ft.

Step-by-step explanation:

The length of the shaded region is (15 - 4) feet

The width of the shaded region is (14 - 6) feet

hence the expression for area is

(15 - 4) x (14 - 6) square feet.

fyi, if you work this out, you will get

(15 - 4) x (14 - 6)

=11 x 8

= 88 square feet.

Answer:

(15 ft - 4 ft) * (14 ft - 6 ft)

Step-by-step explanation:

The shaded area is a rectangle.

area of rectangle = length * width

Length of outer rectangle = 15 ft

Length of shaded rectangle = 15 ft - 4 ft

Width of outer rectangle = 14 ft

Width of shaded rectangle = 14 ft - 6 ft

Area of shaded rectangle = length * width = (15 ft - 4 ft) * (14 ft - 6 ft)

Answer:

x=-4/V

Step-by-step explanation:

Add 4 to both sides to cancel out the 4.

So it now the equation is Vx+9=5

Subtract 9 from both sides to cancel out the 9.

Now the equation is Vx=-4

Divide V to both sides to get x alone.

The answer being x=-4/V

For this case we must find the value of "x" of the following equation:

[tex]\sqrt {x + 9} -4 = 1[/tex]

We add 4 to both sides of the equation:

[tex]\sqrt {x + 9} = 4 + 1\\\sqrt {x + 9} = 5[/tex]

We raise both sides of the equation to the square to eliminate the radical:

[tex]x + 9 = 5 ^ 2\\x + 9 = 25[/tex]

We subtract 9 from both sides of the equation:

[tex]x = 25-9\\x = 16[/tex]

Answer:

[tex]x = 16[/tex]

Glaciers are the cornerstone of life on Earth. As vast freshwater reservoirs, they support the Earth's life system and affect our daily lives, including communities that live far away. But glaciers are disappearing. The disappearing glacier reveals the tallest glacier on Everest, which has lost ice for 2,000 years since the 1990s.

Even the highest mountains in the world are not safe from climate change. Even the glaciers of Everest are unsafe from climate change, new research suggests. Glacier ice turns blue because the red (long wavelength) part of white light is absorbed by the ice and the blue (short wavelength) part is transmitted and scattered. The longer the pass light travels through the ice, the bluer it looks.
