pogonyaev

100%-26%=74%

x=the original price

$\frac{0.74}{1}$ = $\frac{463.98}{x}$

$\frac{463.98}{0.74}$ = $\frac{0.74x}{0.74}$

627=x

The original price was $627.

allochka39001 [22]

Answer:

See explanation

Step-by-step explanation:

<u>Definition:</u> $S\times T=\{(s,t)|s\in S,\ t\in T\}$

<u>Given:</u> $S=\{4,6,8\},\ T=\{3,5,7\}$

1. Find $S\times T:$

$S\times T=\{(4,3),(4,5),(4,7),(6,3),(6,5),(6,7),(8,3),(8,5),(8,7)\}$

There are 9 elements.

2. Find $T\times S:$

$T\times S=\{(3,4),(3,6),(3,8),(5,4),(5,6),(5,8),(7,4),(7,6),(7,8)\}$

There are 9 elements.

3. Find $S\times S:$

$S\times S=\{(4,4),(4,6),(4,8),(6,4),(6,6),(6,8),(8,4),(8,6),(8,8)\}$

There are 9 elements.

4. Find $T\times T:$

$T\times T=\{(3,3),(3,5),(3,7),(5,3),(5,5),(5,7),(7,3),(7,5),(7,7)\}$

A line includes the points (0, 3) and (-1, -1). What is its equation in slope-intercept form?

SpyIntel [72]

Answer:
y = 4x+3

----------------------------------------------

Explanation:

use the slope formula first
m = (y2-y1)/(x2-x1)
m = (-1-3)/(-1-0)
m = (-4)/(-1)
m = 4
The slope is m = 4

The y intercept is b = 3 because this comes from the point (0,3)
The x value is always 0 for the y intercept. This is where the graph crosses the y axis

Since m = 4 and b = 3, we go from y = mx+b to y = 4x+3
