The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.

Sample Answer: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.

Answer:

5%

Step-by-step explanation:

Given the following question:

The item costs 60 dollars
The shipping costs was 3 dollars

What was the percent of 60 is 3?

To find the answer we divide the shipping fee by the cost and then multiply the answer by 100.

[tex]\frac{3}{60} =3\div60=0.05\times100=5[/tex]
[tex]=5[/tex]

3 dollars is "5 percent" of 60 dollars.

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is [tex]\frac{5y_2+y_1}{6}[/tex]

Let point P(x,y) cuts line joining point  [tex]A(x_1,y_1)[/tex] and [tex]B(x_2,y_2)[/tex]  in [tex]m_1:m_2[/tex] then coordinate of point P is equal to [tex](\frac{m_1x_2+m_2x_1}{m_1+m_2}, \frac{m_1y_2+m_2y_1}{m_1+m_2})[/tex]

Here given that point divides line segment from J to K into a ratio 5:1

So

[tex]m_1=5\\\\m_2=1[/tex]

Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1

We can calculated y coordinate by applying section formula as :

[tex]\frac{5y_2+1y_1}{5+1}\\\\\frac{5y_2+y_1}{6}[/tex]

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is [tex]\frac{5y_2+y_1}{6}[/tex]

The value of (8x^(3)-24x^(2)y^(2)+36x)-:6x is 4x^2/3 - 4xy^2 + 6

Step-by-step explanation:

Answer:

Step-by-step explanation:

It's Irrational.

sqrt(70) = sqrt(2 * 5 * 7)

You can't pull anything out of the right to leave the number under the root sign = to 1. That means that since all three roots are irrational, the whole number is irrational, In fact it takes only 1 number other than 1 left under the root sign to make the result irrational.

√50 = √(5 * 5 * 2)

The 5's will produce one number outside the root sign -- five. That makes the result

5√2 The result is irrational because √2 is irrational

Answer: x = 4

Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.

Answer:

He needs to sell 12 to get exactly $30 but he needs to sell at least 13 if he wants to earn more than $30

Answer:

13 or more magazines.

[tex]30 / 2.5 = 12[/tex]

[tex]12 * 2.5 = 30[/tex]

In that case, anything equal to or greater than 13 is correct.

Step-by-step explanation:

1. d = rt

Divide t from both sides.

[tex]\frac{d}{t} = r[/tex]

2. PV = nRT

Divide P from both sides.

[tex]V = \frac{nRT}{P}[/tex]

3. [tex]\frac{x}{2} -g=a\\[/tex]

Add g to both sides.

[tex]\frac{x}{2}[/tex] = g + a

Now multiply by 2 on both sides.

x = 2(g + a)

(or, x = 2g + 2a)

4. g[tex](h+\frac{3}{2} ) = 11[/tex]

Divide g from both sides.

[tex]h + 1.5 = \frac{11}{g}[/tex]

Now subtract 1.5 from both sides.

h = [tex]\frac{11}{g} -1.5[/tex]

5. [tex]a(n-2)+5=bn\\[/tex]

Answer:

12a. 45+0.5x+2x+x = 150

12b. the three unknown sides are 30ft, 60ft, and 15ft.

Step-by-step explanation:

12a. the fence is 150ft. so

45+0.5x+2x+x = 150

12.b solve the equation from 12a.

45+0.5x+2x+x = 150

7x/2 = 105

7x = 210

x= 30

0.5(30) = 15ft

2(30)=30ft

x= 30ft

the three unknown sides are 30ft, 60ft, and 15ft.

Answer:

12a. 45+0.5x+2x+x = 150

12b. the three unknown sides are 30ft, 60ft, and 15ft.

Step-by-step explanation:

12a. the fence is 150ft. so

45+0.5x+2x+x = 150

12.b solve the equation from 12a.

45+0.5x+2x+x = 150

7x/2 = 105

7x = 210

x= 30

0.5(30) = 15ft

2(30)=30ft

x= 30ft

the three unknown sides are 30ft, 60ft, and 15ft.

Answer:

Some of the possible combinations are;

1) $19 per adult, $0 per child

2) $10 peer adult, $9 per child

3) $14 peer adult, $5 per child

Step-by-step explanation:

The given information are;

The estimated number of adults to attend the fund raising dinner = 200 adults

The amount the fund raiser is trying to realize = 3800

Therefore, some of the possible combinations are;

1) 3800/200 = 19 per adult to give;

$19 per adult, $0 per child

2) Given that each adult is charged $10, we have;

Total amount from adults = $10 × 200 = $2000

The total amount to be raised from the children = The amount the fund raiser is to realize - (Total amount from adults)

∴ The total amount to be raised from the children = 3800 - 2000 = 1800

The total amount to be raised from the children = $1,800

If there are 200 children we have;

The amount charged per child = (The total amount to be raised from the children)/(The total number of children)

The amount charged per child = $1,800/200 = $9 per child

Therefore, we have;

$10 peer adult, $9 per child

3) If each of the 200 children are charged $5 each, we have;

The total amount to be raised from the children = $5 × 200 = $1,000

∴ The amount to be raised from adults = $3800 - $1000 = $2800

The amount to each adult is to be charged = $2800/200 = $14

Therefore, we have;

$14 peer adult, $5 per child.

Answer: 250

Step-by-step explanation:

The value of interest rate should be 0.085.

We have given that the interest rate is 8.5% So we have given in percentage form but we use always decimal form of interest.

To convert a percentage to a decimal, divide by 100.

So the decimal form of the 8.5% is calculated by

[tex]\frac{8.5}{100}=0.085[/tex]

Therefore the option c is correct.

Therefore we use the interest rate is 0.085.

Volume of the prism: 120cm^3

Step-by-step explanation:

volume of a prism = area of cross-section x length

so

volume of triangular prism = 4 (h) x 6 (b) divided by 2 x 10 (length)

6 x 4 = 24

24 / 2 = 12

12 x 10 = 120
