The number has 2 digits - let's call them x and y. The positive difference between the two combinations (lowest-highest and highest-lowest) is always equal to the positive difference of x and y, multiplied by 9.

For example:

76 and 67: 76 - 67 = 9 and ((7-6)*9) = 1*9 = 9
73 and 37: 73 - 37 = 36 and ((7-3)*9) = 4*9 = 36

What is the area of the circle below, in terms of ?90 metersO 457O 907O 1807O 81007134

defon

Step 1: Write out the formula

$\begin{gathered} \text{Area of a circle = }\pi r^2 \\ \text{where } \\ r=\text{ the radius of the circle} \end{gathered}$

Step 2: Write out the given values and substitute them into the formula

$r=90m$

Therefore,

$\text{ the area of the circle = }\pi(90)^2=\pi\times8100=8100\pi m^2$

Hence, the area in terms of pi is

$8100\pi$

The last choice is the correct answer

A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3).

adell [148]

Answer:

$y=\frac{3}{2}x-3$

Step-by-step explanation:

The given line passes through: (0,-3), (2,0), and (4,3).

We first of all find the slope using $m=\frac{y_2-y_1}{x_2-x_1}$

Using $(x_1=0,y_1=-3),and\:(x_2=2,y_2=0)$ we find the slope to be

$m=\frac{0--3}{2-0}=\frac{3}{2}$

The equation is given by $y=mx+c$ , where $m=\frac{3}{2}$ is the slope and c=-3 is the y-intercept.

Therefore the equation is $y=\frac{3}{2}x-3$
