Answer:

5/14

Step-by-step explanation:

To find the slope using two points

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

   = ( -1 - -6)/( 5 - -9)

   = ( -1 +6)/ ( 5+9)

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:

9xy = 3x . 3y

2xyz = 2x . y . z

4x . 4y = 16xy

Answer:

1, 4, 5.

Step-by-step explanation:

1. 3x * 3y is equal to 9y.

4. 2x * y * z is equal to 2xyz, since the grouped variables mean the same thing as multiplied.

5. 4x * 4y is 16xy, because 4 * 4 is 16 and x * y is xy.

Answer:

2384.83 cm³

Step-by-step explanation:

Volume = πr² * h

Volume = 3.14 * 7² * 15.5

Volume = 3.14 * 49 * 15.5

Volume = 2384.83

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.

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]

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:

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

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:

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

Answer:

This idea of reflection correlating with a mirror image is similar in math.

This complete guide to reflecting over the x axis and reflecting over the y axis will provide a step-by-step tutorial on how to perform these translations.

 First, let’s start with a reflection geometry definition

Math Definition: Reflection Over the X Axis

A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image. In this case, the x axis would be called the axis of reflection.

Math Definition: Reflection Over the Y Axis

A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image. In this case, theY axis would be called the axis of reflection.

What is the rule for a reflection across the X axis?

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
