Select the three equations that pass through the points (-4, -16) and (5,2).

dezoksy [38]

Answer:

The equation of the line is $y-2 = 2(x - 5)$ , that passes through points $(-4, -16)\ and\ (5,2)$

Step-by-step explanation:

Given points are $(-4, -16)\ and\ (5,2)$

We need to write the equation of the line that passes through these points

First, we will find slope of this line

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-(-16)}{5-(-4)}\\\\m=\frac{2+16}{5+4}\\\\m=\frac{18}{9}=2$

So, our slope is $2$ . Now, we will plug the point $(5,2)$ in the equation below.

$(y-y_1)=m(x-x_1)\\y-2=2(x-5)\\$

So, the equation of the line is $y-2 = 2(x - 5)$ .

When you add 18 to 1/4 of a number you get the number itself

JulijaS [17]

X - the number

$\frac{1}{4}x+18=x \\
18=x-\frac{1}{4}x \\
18=\frac{3}{4}x \ \ \ |\times \frac{4}{3} \\
18 \times \frac{4}{3} = x \\
6 \times 4=x \\
x=24$

The number is 24.

12. Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets. How many ways can the eight cookbooks b

Ghella [55]

Answer:

The number of ways are 40320.

Step-by-step explanation:

Consider the provided information.

Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.

We need to determine the number of different ways to put eight cookbooks on the shelf.

We need to select 8 cookbooks taking 8 at a time.

So use the permutation formula: $^{n}P_{n}$

Substitute n=8 and simplify.

$^8P_8=\frac{8!}{(8-8)!}\\8!=40320$

Hence, the number of ways are 40320.
