A line passes through point A (14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value
that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.

?:(

Answers

Answer 1

Answer:

The equation of the line in point-slope form is [tex]y-21 = - \frac{3}{2}\cdot (x-14)[/tex].

Step-by-step explanation:

According to the statement, let [tex]A(x,y) = (14,21)[/tex] and [tex]B(x,y) = (1.25\cdot x_{A},0.75\cdot y_{A})[/tex]. The equation of the line in point-slope form is defined by the following formula:

[tex]y-y_{A} = m\cdot (x-x_{A})[/tex] (1)

Where:

[tex]x_{A}[/tex], [tex]y_{A}[/tex] - Coordinates of the point A, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

In addition, the slope of the line is defined by:

[tex]m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)

If we know that [tex]x_{A} = 14[/tex] and [tex]y_{A} = 21[/tex], then the equation of the line in point-slope form is:

[tex]x_{B} = 1.25\cdot (14)[/tex]

[tex]x_{B} = 17.5[/tex]

[tex]y_{B} = 0.75\cdot (21)[/tex]

[tex]y_{B} = 15.75[/tex]

From (2):

[tex]m = \frac{15.75-21}{17.5-14}[/tex]

[tex]m = -\frac{3}{2}[/tex]

By (1):

[tex]y-21 = - \frac{3}{2}\cdot (x-14)[/tex]

The equation of the line in point-slope form is [tex]y-21 = - \frac{3}{2}\cdot (x-14)[/tex].

The school store sells markers for $0.25 each and pencils for 0.50 each.Anthony spent $ 5.50 to buy a total of 16 markers and pencils. How many markers did Anthony buy?

Answers

Answer:

The answer to your question is Antony bought 5 pens

Step-by-step explanation:

pens = p = $0.35

pencils = n = $0.15

total amount = 12

total money spent = $2.80

Process

1.- Write equations

              p  +  n  = 12                -------------- (l)

       0.35p  +  0.15n = 2.80      --------------(ll)

2.- Solve the system of equations by elimination

Multiply equation l by - 0.35

        - 0.35p - 0.35n = -4.2

          0.35p + 0.15 n = 2.8

             0      - 0.2n = -1.4

Solve for n

                        n = -1.4 / -0.2

                        n = 7      He bought 7 pencils

3.- Find the value of p

             p + 7 = 12

             p = 12 - 7

             p = 5                He bought 5 pens

Add 7 to both the seven and the two and you get 3x = 9. Next, you divide 3 by both sides and get x = 3.

1. Let x = 3
3 x 3 - 7 = 2

2. Simplify 3 x 3 to 9
9 - 7 = 2

3. Simplify 9 - 7 to 2
2 = 2

Answer:

B

Step-by-step explanation:

x < 1 means that x is lesser than 1. A shows x is more than 1 so it is wrong. C shows x is more than -1 which is not entirely true since x could be more than -1, but not less than 1. However, the line in C stretches all the way to 8 which is more than 1 so it is wrong.  D shows that x is lesser than -1, but x could have been 0 or -1, so it is not true either.

1. Fiona Wolfe regular pay is $9 an hour and time-and-a-half for anything over 40 hours. Last week she worked 46 hours at her full-time job. She also worked 7 hours last week at a part-time job that pays $11 an hour. What total gross pay did she earn last week from both jobs?

Answers

Answer:

$518

Step-by-step explanation:

The total gross payment = full-time payment + part-time payment

Given that:

She worked 46 hours for her full-time payment and time-and-a-half for anything and she is being paid $9 per hour;

and also worked for 7 hours for her part-time payment and she is being paid $11 per hour and time-and-a-half for anything

Then, the total gross payment = $46(9 1/2) + $7(11  1/2)

The total gross payment = $46(9.5) + $7(11.5)

The total gross payment = $437 + $80.5

The total gross payment = $517.5

The total gross payment ≅ $518
