What is the value of x?

main khud dhoond rha tha asignment  ke waqt

Answer:

A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.

Answer:

Z score associated with sleeping 503 minutes = 0 minutes

Step-by-step explanation:

Given values of sleep per night for adults:

Mean value X = 503

Standard deviation σ = s

FInd:

Z score associated with sleeping 503 minutes

Computation:

⇒ P[X = 503]

⇒ P[(x - X) / σ] = [503 - 503] / s

⇒ Z score value = [0] / s

⇒ Z score value = 0

Z score associated with sleeping 503 minutes = 0 minutes

Answer:

0

Step-by-step explanation:

We can use the slope formula since we have two points

m = ( y2-y1)/(x2-x1)

   = ( -2- -2)/(3-14)

   = ( -2+2)/(3-14)

    = 0/-11

   = 0

Answer:

0 is the slope of the line that contains the points (14,-2) and (3,-2)

Step-by-step explanation:

To find , the slope is the slope of the line that contains the points (14 , -2)and (3, -2)

we using slope formula which is

Where,

m , is the slope

( y ² - y ¹ ) = ( 14 , - 2)

( x ² - x ¹) = (3, -2 )

Substitute the values into the formula

m = (( -2 )- ( -2 ) ) / (3 - 14 )

m= ( -2 + 2 ) / ( 11)

m = 0 / 11

m = 0

Therefore , 0 is the slope of the line that contains the points (14,-2) and (3,-2)

Step-by-step explanation:

There are 399 stones in the pyramid of 19 layers if there are 3 stones at the top and 2 more stones in each layer below this

An equation is an expression that shows the relationship between two or more numbers and variables.

A small pyramid has 3 stones at the top and 2 more stones in each layer below this. This can be represented as an arithmetic progression with first term (a) = 3 and difference (d) = 2, hence:

number of stones in 19 layers = [tex]\frac{19}{2}(2(3)+(19-1)2)=399[/tex]

Hitting a red light three days in a row

Solution :

Let, equation of line is y = mx + c .

Here, m is the slope( or gradient ) of the line and c is the y-intercept .

Putting point ( -6, -10 ) in above equation, we get :

-10 = -6m + c  ...1)

Also, putting point ( -3, -8 ) in above equation, we get :

-8 = -3m + c ...2)

Solving equation, 1) and 2) we get :

[tex]m = \dfrac{2}{3}\ and \ y = - 6[/tex]

Therefore, the gradient for the given x-y table is [tex]\dfrac{2}{3}[/tex] .

Answer:

-1, -17/20, -4/5, 0, 3/4

Step-by-step explanation:

Answer:

-1, -17/20, -4/5, 0, 3/4

the x intercepts would be the right and left number (-5.196,0) (5.196) usually most of times the x intercepts would have negative and positive same answers and they usually run vertically while they y intercepts is where the the x and y intercepts meet they usually meets in the y axis so that would be (0,5.4) that is my way of explaining it.

Solution :

Let, equation of line is y = mx + c .

Answer:

it's a factor the expression using GCF

Answer:

y = 3x + 4

Step-by-step explanation:

slope = (y2 -y1)/(x2 - x1)

y2 = 19

y1 = 7

x2 = 5

x1 = 1

Slope = (19 - 7)/(5 - 1)

slope = 12 / 4

slope = 3

So far what you have is

y = 3x + b                      To solve for b, use either of the two points.

x = 1

y = 7

7 = 3(1) + b

7 = 3 + b

b = 4

The final equation is

y = 3x + 4                    

We should check that with the other  point

x = 5                  Find y

y = 3(5) + 4

y = 15 + 4

y = 19              Ans it checks.

Answer:

3(2x + 1)(3x - 5)

Step-by-step explanation:

Given

18x² - 21x - 15 ← factor out 3 from each term

= 3(6x² - 7x - 5 ) ← factor the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 5 = - 30 and sum = - 7

The factors are + 3 and - 10

Use these factors to split the x- term

6x² + 3x - 10x - 5 ( factor the first/second and third/fourth terms )

3x(2x + 1) - 5(2x + 1) ← factor out (2x + 1) from each term

(2x + 1)(3x - 5)

Then

18x² - 21x - 15 = 3(2x + 1)(3x - 5)

Answer:

10.8 mi

Step-by-step explanation:

Picture a right triangle with legs 9 mi and 6 mi.  Applying the Pythagorean Theorem (d² = a² + b²), we get:

(9 mi)² + (6 mi)² = 117 mi²

This is the square of the hypotenuse (the desired distance).

Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d

The desired straight line distance traveled is 10.8 mi

Answer:

x=10

Step-by-step explanation:

To solve for x, you need to draw an imaginary line connecting the right end of side x to the left side with length 15. This forms a triangle with side lengths 6 and 8, and hypotenuse x. Using the Pythagorean Theorem to solve for x, we get 6^2 + 8^2 = x^2, 36 + 64 = 100, [tex]\sqrt{100}[/tex] = 10.

Answer:

It's 10

Step-by-step explanation:

C^2=A^2+B^2blank

C=√(A^2+B^2)

If c is x and a and b are the side lengths the we can use Pythagoras's theorem to calculate the length of the line. A=6 B=8 and in the end when you calculate all that doohickey stuff you get x=10
