To graph the equation 2x + 5y = 10, Zeplyn draws a line through the points (5, 0) and (0, What is the slope of the line represented by 2x + 5y = 10?

Answers

Answer: -2/5

Step-by-step explanation:

To find the slope, we set the function use y = mx + b forms.

2x + 5y = 10

        5y = -2x + 10              Minus 2x in both side

           y = -2/5x + 10/5       Divide 5 from both side

           y = -2/5x + 2

In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.

(Round your answer to four decimal places.) 48.6364 cm (b) Calculate the sample variance and standard deviation for this data set. (Round your answers to four decimal places.) Variance Standard deviation

Answers

Answer:

[tex]Mean = 48.6364[/tex]

[tex]s^2 = 331.8545[/tex] -- Sample Variance

[tex]s = 18.2169[/tex] --- Sample Standard Deviation

Step-by-step explanation:

Given

[tex]n = 11[/tex]

[tex]Data: 24, 41 ,25 ,68 ,53 ,83 ,43 ,63 ,56 ,34 ,45[/tex]

Solving (a): The sample mean

[tex]Mean = \frac{\sum x}{n}[/tex]

So:

[tex]Mean = \frac{24 +41 +25 +68 +53 +83 +43 +63 +56 +34+ 45}{11}[/tex]

[tex]Mean = \frac{535}{11}[/tex]

[tex]Mean = 48.6364[/tex]

Solving (b): Sample variance (s^2)

This is calculated as:

[tex]s^2 = \frac{\sum (x - \bar x_i)^2}{n - 1}[/tex]

Where:

[tex]\bar x = 48.6364[/tex]

So:

[tex]s^2 = \frac{(24 -48.6364)^2 +(41 -48.6364)^2 +......................+( 45 -48.6364)^2}{11-1}[/tex]

[tex]s^2 = \frac{3318.54545456}{10}[/tex]

[tex]s^2 = 331.8545[/tex]

Solving (c): Sample Standard Deviation (s)

This is calculated as:

[tex]s = \sqrt {s^2[/tex]

[tex]s = \sqrt{331.8545[/tex]

[tex]s = 18.2169[/tex]

Solve the system using substitution.
X + 2y = -6
6x + 2y = 4
([?], [ ]

Answers

Answer:

Step-by-step explanation:

Rearrange x+2y=-6 to solve for x:

x = -2y-6

substitute -2y-6 for x into the second equation:

6x + 2y = 4

6(-2y-6) + 2y = 4

-12y-36 + 2y = 4

-10y  = 40

y  = -4

x = -2y-6 = 2

(x,y) = (2,-4)

The solution for the system of equations is (2,-4).

The given system of equations are x + 2y = -6-----(1) and 6x + 2y = 4-----(2).

How do solve systems of equations using the substitution method?

To solve a system of equations using substitution:

Step 1: Isolate one of the two variables in one of the equations.Step 2: Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. This should result in a linear equation with only one variable.Step 3: Solve the linear equation for the remaining variable.Step 4: Use the solution of Step 3 to calculate the value of the other variable in the system by using one of the original equations.

Now, rearrange x+2y=-6 to solve for x:

So, x = -2y-6

Substitute -2y-6 for x into the second equation 6x + 2y = 4.

That is, 6(-2y-6) + 2y = 4

⇒-12y-36 + 2y = 4

⇒-10y = 40

⇒y = -4

By substituting y = -4 in x = -2y-6 we get x=2.

Therefore, the solution for the system of equations is (2,-4).

Answers

Answer: One solution!!

I checked desmos and it only intersected at one point :)

Answer: The answer is ONE Solution

Step-by-step explanation:

A system of equations have no solution when their slopes are the same but they have different y-intercepts. When graphed, the lines cannot intersect for there to be a solution. Looking at both equations, they have different slopes and different y intercepts so you can rule "NO solution" out.

Secondly a system of equations have infinitely many solution if they both share the same slopes and y-intercepts.

Looking at both lines, they have different slopes and different y-intercepts, so you can also rule that out.

A system of equations have one solution if their slopes are different and y intercepts are also different. Looking at the two lines, we can notice that the slope and y-intercepts are all different.

An observer is watching a bird from the ground as shown. What is the bird's distance from the ground, in miles, as shown in the diagram? Round to the nearest tenth.

Answers

Answer:

? = 1.5 miles

Step-by-step explanation:

? = 1.473

The distance of bird from the ground is 1.47 miles.

What is a right angle triangle?

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

In the given diagram,

The distance between observer and bird = 1.9 miles,

And the distance from observer to the ground = 1.2 miles.

Let the distance of bird from ground is h miles.

To find the distance of bird from ground,

Use Pythagoreans theorem,

(1.9)² = (1.2)² + h²

3.61 = 1.44 + h²

3.61 - 1.44 = h²

2.17 = h²

h = 1.473 miles

The distance of bird from the ground is 1.47 miles.

somebody help please

Answers

Answer:

The last one

Step-by-step explanation:

The fast reason why - all the other scenarios require 3 lines: 2 lines both parallel to a 3rd, or 2 lines cut by a transversal line, etc. The diagram only shows 2 lines. So the right answer must be the one that doesn't require a third line to be present.  :)

The longer answer why - See how angles 2 & 3 have the same style of arc? That is telling you they are of equal measure. So together they are a straight angle, 180°. And they are equal to each other, so 2x = 180° --> each one must be a 90° angle.

Wherever two lines cross, if one angle is a right angle, all 4 angles at the intersection also must be right angles, so everything is perpendicular.
