Answer:

y + 10 = 0

Step-by-step explanation:

Slope of horizontal line is zero (0)

m = 0

By point slope form of a line.

$y-y_1 =m(x - x_1) \\ \\ y - ( - 10) = 0 \{x - ( - 7) \} \\ \\ y + 10 = 0 \{x + 7\} \\ \\y + 10 = 0 \\ \\$

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Brut [27]

Answer:

c ≈ 5.5 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

c² = 2.4² + 4.9² = 5.76 + 24.01 = 29.77 ( take square root of both sides )

c = $\sqrt{29.77}$ ≈ 5.5 cm ( to the nearest tenth )

Answer:

$12 + 4b < 7.50b$

Step-by-step explanation:

Given

Reader' Book Club

$Membership = \$12$

$Book = \$4.00$ per book

Perfect Page

$Book = \$7.50$ per book

Required

Write an inequality to represent the situation

Represent the number of books with b

First, we need to write an expression for Reader's book

This is:

= Membership + Books Read

$12 + 4b$

For Perfect Page

This is

= Books Read

$7.50b$

For Reader's club to be less than Perfect Page, we have:

$12 + 4b < 7.50b$

For a production of sweeney todd in las vegas, orchestra seats cost $42 and mezzanine seats cost $25. if a group of 14 people sh

Lesechka [4]

Answer: 8 orchestra seats and 6 mezzanine seats.

Step-by-step explanation:

Let be "o" the number of orchestra seats they bought and "m" the number of mezzanine seats they bought.

Set up a system of equations:

$\left \{ {{42o+25m=486} \atop {o+m=14}} \right.$

You can apply the Substittution Method to solve the system of equations:

1. Solve for "o" from the second equation:

$o=14-m$

2. Substitute it into the first equation and solve for "m":

$42(14-m)+25m=486\\\\588-42m+25m=486\\\\-17m=-102\\\\m=\frac{-102}{-17}\\\\m=6$

3. Substitute the value of "m" into $o=14-m$ and evaluate, in order to find the value of "o". This is:

$o=14-6\\\\o=8$
