A line passes through the points (4, 9) and (12, 20). What is the slope of the line?

Mashutka [201]

Answer:

$\frac{11}{8}$

Step-by-step explanation:

→ State the gradient formula

( y₂ - y₁ ) ÷ ( x₂ - x₁ )

→ Find x₁ , x₂ , y₁ and y₂

x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20

→ Substitute in the values

$\frac{20-9}{12-4}$

→ Simplify

$\frac{11}{8}$

There are nine empty seats in a theater, and six customers need to find places to sit. How many different ways can these six sea

dybincka [34]

Answer: 60480

Step-by-step explanation:

Given : The number of empty seats in a theater = 9

The number of customers need to find places to sit =6

Since order matters here, so we use permutations

The permutations of n things taking r at a time is given by :-

$^nP_r=\dfrac{n!}{(n-r)!}$

Then, the number of ways to arrange 6 seat in 9 seats :-

$^9P_6=\dfrac{9!}{(9-6)!}=\dfrac{9\times8\times7\times6\times5\times4\times3!}{3!}\\\\=60480$

Hence, the number of ways to arrange 6 seat in 9 seats = 60480

The simplest form of the given expression $3\frac{11}{12} - 1\frac{4}{12}$ is $\frac{31}{12}$

<u>Solution:</u>

Given, expression is 3 11/12 – 1 4/12 $\rightarrow 3 \frac{11}{12}-1 \frac{4}{12}$

We have to find the simplest form of the value derived from the given expression.

Now, first let us solve the given equation.

$3 \frac{11}{12}-1 \frac{4}{12}$

converting mixed fractions to improper fractions.

$=\frac{3 \times 12+11}{12}-\frac{1 \times 12+4}{12}$

$\frac{36+11}{12}-\frac{12+4}{12}=\frac{47}{12}-\frac{16}{12}=\frac{47-16}{12}=\frac{31}{12}$

As there are no common terms to cancel it is in lowest form.

Hence, the lowest form of the given expression is $\frac{31}{12}$

How is adding and subtracting radical expressions similar to adding and subtracting variables ?????

steposvetlana [31]

Answer: To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.
