Veronica takes of an hour to write of a page of calligraphy.
How long will it take Veronica to write one page of calligraphy?

Answers

Using proportions, it is found that it will take Veronica 4/3 of an hour to write one page of calligraphy.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, it is found that she takes 1/3 of an hour to write 1/4 of a page of calligraphy. How long it takes her to write a page?

The rule of three is:

1/3 hour - 1/4 page

x hours - 1 page

Applying cross multiplication:

[tex]\frac{x}{4} = \frac{1}{3}[/tex]

[tex]x = \frac{4}{3}[/tex]

It will take Veronica 4/3 of an hour to write one page of calligraphy.

x = 77

x = Adam

x + 8 = Holly

Therefore, Adam - 77 / Holly - 85.

Answer:

k = 9

Step-by-step explanation:

For this, we can factor the top expression to look like the bottom expression.

So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.

18[tex]x^{2}[/tex]            11x

1 and 18       19   - No

2 and 9       11    - Yes

3 and 6       9    - No

So, the numbers are 2 and 9. The expression should now look like this:

[tex]x^{2}[/tex] + 2x + 9x + 18

Now, undistribute the terms.

x(x + 2) + 9(x + 2)

(x+2)(x+9)

This matches up with the bottom expression.

The value of k is 9.

what is the equation of the line that passes through the points (11, - 4) and (13,- 7) in slope-intercept form?
answer choices shown in picture

Answers

Answer:

E. None of these

Step-by-step explanation:

Points: (11, -4), (13, -7)

slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2

y - y1 = m(x - x1)

y - (-4) = (-3/2)(x - 11)

y + 4 = (-3/2)x + 33/2

y + 8/2 = (-3/2)x + 33/2

y = (-3/2)x + 25/2

Answer: E. None of these

Step-by-step explanation:

A(11,-4) B(13,-7)

x1 y1 x2 y2

y=mx+c

-4=11m+c -(i) -7=13m+c -(ii)

Subtract equation (ii) from (i)

-7=13m+c

-4=11m+c

+ - -

-3=2m

2m=-3

m=-3/2

put m=-3/2 in equation (ii)

-7=13*(-3/2)+c

c=-7+39/2

c=(-14+39)/2

c=15/2

y=mx+c

y=-3/2x+15/2

y=(-3x+15)/2

2y=-3x+15

2y+3x-15=0

Answer: x > -1

Step-by-step explanation:

1) Subtract 5 from both sides

-3(4x - 5) < 27

2) Divide both sides by -3 (Remember to change the inequality sign to face the other way, because you have multiplied/divided by a negative number)

4x - 5 > -9

3) Add 5 to both sides

4x > -4

4) Divide by 4 on both sides
