how do you graph y= 6/5x + 1?​

Answers

Answer:

Start at postive 1 on the y axis put a dot there. From the dot go down 6 and go left 5.

Step-by-step explanation:

6/5=rise over run

1=y-axis

y=mx+b

m=slope

b=y-intersept

Step-by-step explanation:

Hey, there!!

To graph a equation, we must find the coordinates of x and y.

So, as the equation is,

[tex]y = \frac{6}{5} x + 1[/tex]

Here, the equation is for finding the coordinates of y and x should be supposed. Remember, always suppose the value in equal interval.

Now,

x = 0 1 2 3

y= 1 2.2 3.4 4.6

Here, if you are confused how do i get 1, 2.2,3.4,4.6 as y value, put the value of x such as,

[tex]y = \frac{6}{5} \times 0 + 1[/tex]

which is equal to 1.

so,in this we got values.

Now,

List coordinates,

(0,1),(1,2.2),(2,3.4),(3,4.6)

Then plot on graph!!!

We’re five and twenty two hundredths centimeters as a decimal

Answers

You answer will be 5 22/100

Five and twenty-two hundredths centimeters as a decimal will be 5.22.

What are decimal values?

A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole amounts.

Given, we need to find out the five and twenty-two hundredths centimeters as a decimal. Since five is a whole number so it will be 5 and twenty-two hundredths will be 0.22.

Therefore, 5.22 is the decimal value of the given question.

divide 68 into two parts so that the larger number exeed the smaller one by 6

Answers

Answer:

31, 37

Step-by-step explanation:

Let the smaller number be x

Therefore, longer number = x + 6

According to the given information:

x + x + 6 = 68

2x + 6 = 68

2x = 68 - 6

2x = 62

x = 62/2

x = 31

x + 6 = 31 + 6 = 37

Thus, the two parts of 68 are 31 and 37.

Answers

Answer:

Solution:

[tex]\frac{\left(y-1\right)^2}{9}-\frac{\left(x+4\right)^2}{4}=1[/tex]

Step-by-step explanation:

We have the general equation for our up - down facing hyperbola as (y - k)² / b²- (x - h)² / a²  = 1. Let's start listing the properties of this graph -

• Taking a look at the graph we see that the center point of our hyperbola here is (- 4, 1). Therefore (h, k) = (- 4,1).

• Another thing here is our key value a. This is the semi distance from the center to one of the vertices. Here it will be the distance from points (- 4,1) and (- 4,4) or 3 unit difference. Therefore a = 3.

• That leaves us with our asymptotes. Now remember that it will be in the form y = ± b / a. We already know a = 3, so we have to find b. Looking at this graph I can say that another point besides (- 4,1) that lies on the " dotted line " is (- 2, - 2). Calculating the slope of the dotted line would be as follows,

Given: (- 4,1) and (- 2, - 2)

Slope = - 2 + 4 / - 2 - 1 = 2 / 3

We have the equation y = 2 / 3x. Therefore b = 2. Let's substitute to receive our equation...

h = - 4, k = 1, b = 2, a = 3

(y - 1)² / (3)²- (x + 4)² / (2)²  = 1

(y - 1)² / 9 - (x + 4)² / 4  = 1 ~ your solution is the last one, option d

Express the following in the usual form
(a) 6.25×10-⁵

Answers

Answer:

0.0000625

Step-by-step explanation:

[tex]10^{-5}=0.00001[/tex]

[tex]6.25*10^{-5}=6.25*0.00001=0.0000625[/tex]

Answer:

So we need to express [tex]6.25 * 10^{-5}[/tex].

What is being used here is scientific notation, and when the exponent is negative, that means the number is less than 1.

As the exponent is -5, we have to move the coma 5 positions to the left (if it was positive we would have done that put to the right), so:

[tex]6.25 * 10^{-5}=0.0000625[/tex]

If you don't understand what does it mean to move the coma to the left, see this example to understand it:

We move it one time from 6.25 --> 0.625

We move it two times from 6.25 --> 0.0625

We move it three times from 6.25 --> 0.00625

We move it four time from 6.25 --> 0.000625

What we are doing is adding 0 to the left and if the exponent was positive, we would add 0 to teh right.

So now we know that [tex]\boxed{6.25 * 10^{-5}=0.0000625}[/tex]

There are 10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles in a box. If two marbles are drawn at random without replacement, what is the probability that both marbles removed are not blue?​

Answers

Answer:

7/20

Step-by-step explanation:

10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles = 25 marbles

25-10 = 15

There are 15 not blue marbles

P( not blue ) = not blue marbles / total = 15/25 = 3/5

keep the not blue marble

25-1 = 24 marbles left

15-1 = 14 not blue marbles

P( not blue ) = not blue marbles / total = 14/24 = 7/12

P( not blue, keep, not blue) = 3/5 * 7/12 = 21/60 = 7/20

Answer:

7/20

Step-by-step explanation:

10(blue) + 4(black) + 5(white) + 6(red) = 25(total)

25(total)-10(blue)=15(not blue)

not blue/all = 15/25 = 3/5 = probability that first marble removed are not blue

If we remove 1 marble;

25-1 = 24 (total) , 15-1=14(not blue)

second not blue/all = 14/24 = 7/12 = probability that second marble removed are not blue

probability that both marbles removed are not blue : 3/5. 7/12 = 21/60

21/60 = 7/20

Step-by-step explanation:

Definition of Supplementary Angles: 2 angles adjacent to each other that add up to 180°

Step 1: Define variables

m∠AEC = 50°

m∠AED = x (unknown)

Step 2: Set up equation

50 + x = 180

Step 3: Solve for x (subtract 50 on both sides)

x = 130°

Step 4: Replace variable x

m∠AED = 130°

Answer:130°

Step-by-step explanation: 50° is on a straight line. Therefore 180-50=130

Step-by-step explanation:

Given the graph below, which of the following statements is true? On a coordinate plane, a graph shows an image with three connected lines. The first line has a negative slope and goes from (negative 5, 6) to (negative 2, 0), the second line has a positive slope and goes from (negative 2, 0) to (2, 2), and the third line has a negative slope going from (2, 2) through (4, negative 2). The graph represents a one-to-one function because every x-value is paired with only one y-value. The graph represents a one-to-one function because it is defined for all x-values. The graph does not represent a one-to-one function because it does not pass through the origin. The graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.

Answers

Answer:

The correct option is (D).

Step-by-step explanation:

A one-to-one function can be defined such the every value of x corresponds to exactly one value of y.

That is:

x₁ → y₁

x₂ → y₂

x₃ → y₃

.

.

.

and so on.

Consider the graph.

From the graph it can be seen that for y = 0 and y = 2 there are multiple x coordinates.

So, the graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.

According to the graph it can be concluded that the graph of three lines is not an one one function because the values of 'y' between 0 and 2 are paired with multiple 'x' values.

Given :

On a coordinate plane, a graph shows an image with three connected lines. The first line has a negative slope and goes from (-5, 6) to (-2, 0).The second line has a positive slope and goes from (-2, 0) to (2, 2).The third line has a negative slope going from (2, 2) through (4, -2).

Draw the graph of the three lines in order to determine the function is one-one function or not.

The equation of the line passing through (-5,6) and (-2,0) is given by:

[tex]\dfrac{y-6}{x+5}=\dfrac{0-6}{-2+5}[/tex]

[tex]\dfrac{y-6}{x+5}=\dfrac{-6}{3}[/tex]

[tex]y-6=-2(x+5)[/tex]

y + 2x + 4 = 0    --- (1)

The equation of the line passing through (-2,0) and (2,2) is given by:

[tex]\dfrac{y-0}{x+2}=\dfrac{2-0}{2+2}[/tex]

2y = x + 2   ---- (2)

The equation of the line passing through (2,2) and (4,-2) is given by:

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

y - 2 = -2(x - 2)

y + 2x = 6   ---- (3)

Now, with the help of these three equations, the graph of the three lines can be plotted. The Graph is attached below.

So, according to the graph it can be concluded that the graph of three lines is not an one one function because the values of 'y' between 0 and 2 are paired with multiple 'x' values.

Therefore, the correct option is D).
