the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 0 ) and (x₂, y₂ ) = (0, - 5 )

m = [tex]\frac{-5-0}{0-3}[/tex] = [tex]\frac{5}{3}[/tex]

line crosses y-axis at (0, - 5 ) hence c = - 5

y = [tex]\frac{5}{3}[/tex] x - 5 ← in slope-intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange slope-intercept form into standard form

multiply all terms by 3

3y = 5x - 15 ( subtract 3y and add 15 to both sides )

5x - 3y = 15 ← in standard form → D

Answer:

its d on edgunity

Step-by-step explanation:

Assuming you want the y-intercept of the line through those two points, you can find it a couple of different ways.

The slope of the line is ...

... slope = (change in y)/(change in x) = (6-18)/(6-2) = -12/4 = -3

We are given the y-value for x=2. When x decreases by 2 to x=0, then the y-value changes by (-2)·(-3) = +6, from 18 to 24.

___

You can also write the equation of the line in point-slope form as ...

... y = -3(x -2) +18

Again, when x=0, the y-intercept is ...

... y = -3(0 -2) +18 = 6 +18 = 24

The y-intercept of the line through (2, 18) and (6, 6) is 24.

Remark

You have been told that the slope of the line is 2/3. That means that if the general equation is y = mx + b is the equation for the slope intercept formula and since m = the slope, then m also equals 2/3

y = (2/3)x + b

Use the point to find b

when x = 3

y = 4                       This comes from the point

4 = (2/3) * 3 + b      multiply 2/3 and 3 together

4 = 6/3 + b             Simplify 6/3

4 = 2 + b                  Subtract 2 from both sides

4 - 2 = b                   Combine

2 =  b              

Equation

y = (2/3)x + 2

Hey there!!

What is slope-intercept form ?

Ans :- y = mx + b

Where 'm' is the slope and 'b' is the y-intercept.

Given :

Slope = 2/3

Coordinate : ( 3 , 4 )

Now, plugging in all these values, we get :

... 4 = ( 2/3 )×3 + b

... 4 = 2 + b

b = 2

Hence, the y -intercept is 2.

Getting this into slope-intercept form :

y = ( 2x/3 ) + 2

Subtracting 3 gives the solution:

Step-by-step explanation:

Since we have given that

Amount of pay rate =$21

If she marked up by 78.7% , so it becomes

[tex]78.7\%\text{ of}\$21\\\\=\frac{78.7}{100}\times \$21\\\\=\$16.527[/tex]

So, our amount for pay rate becomes

[tex]21+16.527\\\\=\$37.527[/tex]

Now, he said he made a profit of 10%,so it becomes

[tex]10\%\text{ of }37.527\\\\=\frac{10}{100}\times 32.527\\\\=\$3.7527[/tex]

So, our new pay rate becomes

Your sequence has a common difference of -8, so could be considered an arithmetic sequence with first term 79. A formula for the n-th term might be ...

... a[n] = 79 -8(n -1)

or

... a[n] = 87 -8n

There are several issues with this English description, as there often are.

We assume you mean you want to divide 10 into two equal parts, then subtract one of those parts from 50.

... (10/2) is half of 10

When that is subtracted from 50, the result is

... 50 - (10/2)

We assume you want one fifth of this result. Other interpretations are that you are subtracting 10/2 from (50/5), or that you are using the difference as the denominator with 1/5 or some other number of fifths as the numerator (dividing <the difference> into 1/5).

Then your expression might be ...

... (1/5)(50 -10/2)

There are ways to write math expressions in English so they are unambiguous. This isn't one of them. It must be done very carefully, as English is often intentionally vague and subject to a variety of interpretations (as most human languages are). Good punctuation helps.

The answerer is combining terms in x with constants

that is, 13x + 5 ≠ 18x

13x + 5 + 17x - 4.5 + x

= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms

= 31x + 0.5 ← correct simplification

combining terms in x with constants

13x + 5 ≠ 18x

13x + 5 + 17x - 4.5 + x

Answer:

A) -0.18 rad

Step-by-step explanation:

arcsin(x) = a means that sin(a) = x

For example

arcsin(1) = pi/2.

It means that pi/2 is the value for which the sin is equals to 1.

arcsin(-0.18)

This is the value of x for which sin(x) = -0.18. This happens for x = -0.18 rad.

So the correct answer is:

A) -0.18 rad

Answer:

1) There were 18582 visitors on the opening weekend.

2) There were approximately 7199 visitors on the 9th weekend.

3) The number of visitors was about 15,051 after 2 weekends. 

Step-by-step explanation:

Given : The curve of best fit to model the data is given below.  

[tex]y=18582(0.90)^x[/tex]

To find : Complete the statements,

1) There were _____ visitors on the opening weekend.

2) There were approximately _____ visitors on the 9th weekend.

3) The number of visitors was about 15,051 after ______ weekends.

Solution :

[tex]y=18582(0.90)^x[/tex] is the exponential equation: 

where, y is the number of visitors and x are the weekends since opening

1. Since the opening weekend is the day of the the park's opening.

So, replace x=0 in our exponential equation to get the number of visitors on the opening weekend:

[tex]y=18582(0.90)^x\\y=18582(0.90)^0\\y=18582(1)\\y=18582[/tex]

Therefore, There were 18582 visitors on the opening weekend.

2. To find the approximate number of visitors on the ninth weekend.

We replace x=9  in our exponential equation:

[tex]y=18582(0.90)^x\\y=18582(0.90)^9\\y=7199.0475[/tex]

Rounded to the nearest integer :  y=7199

Therefore, There were approximately 7199 visitors on the 9th weekend.

3. Here, we know that the number of visitors is 15051

Since y represents the number of visitors.

So, replace y=15051 in our exponential equation and solve for x:

[tex]y=18582(0.90)^x\\\\15051=18582(0.90)^x\\\\ \frac{15051}{18582} =0.90^x\\\\0.90^x= \frac{5017}{6194} \\\\ln(0.90^x)=ln(\frac{5017}{6194})\\\\xln(0.90)=ln(\frac{5017}{6194})\\\\x= \frac{ln(\frac{5017}{6194})}{ln(0.90)} \\\\x=2.0002[/tex]

Rounded to the nearest whole number :  x=2

Therefore, The number of visitors was about 15,051 after 2 weekends.

The point-slope form:

[tex]y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-1, 6) and (7, -2). Substitute:

[tex]m=\dfrac{-2-6}{7-(-1)}=\dfrac{-8}{8}=-1\\\\y-6=-1(x-(-1))\\\\y-6=-(x+1)\\\\y-6=-x-1\qqiad|\text{add 6 to both sides}\\\\\boxed{y=-x+5}[/tex]

In order for the equation to work, x must be odd. Trying different values of x, we find 5 solutions:

(x, y, z) = (1, 4, 6), (3, 5, 7), (5, 6, 8), (7, 5, 2), (9, 6, 3)

Then the product xyz could be any of 24, 105, 240, 70, or 162.
