Write an equation that represents the line
Answers
Answer:
y = -2x - 3
Step-by-step explanation:
First, find slope (m) of the line using two points (0, -3) and (1, -5):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-3)}{1 - 0} = \frac{-2}{1} = -2 [/tex]
The line intercepts the y-axis at y = -3. Therefore the y-intercept (b) of the line = -3.
To write the equation that represents the line, substitute m = -2, and b = -3 into y = mx + b.
Thus:
y = -2x + (-3)
y = -2x - 3

Whats the value? 2x+2 + 2x+10 =90
Answers
Answer:
x=19.5 or 19 1/2
Step-by-step explanation:
To find what x is we need to get x on one side of the equal sign with the numbers on the other side, but first, we need to add the same variables and numbers together.
Add:
4x+12=90
Move the 12 to the other side by subtracting 12 on both sides (You use the inverse of what you want to move to the other side)
4x+12-12=90-12
4x=78
Divide:
You need to divide 4x by 4 (Since 4x is the same thing as 4*x you need the inverse of multiplication to reverse it which is division)
x=19.5 or 19 1/2 (Since 1/2 is the same thing as 0.5)

The average attendance at a local high school's football games went down from 1800 people in 2003 to
500 people in 2004. What was the percent decrease in attendance at the football games?
Answers
Step-by-step explanation:
%decrease = 1800 - 500 * 100
__________
1800
%decrease = 1300/1800 * 100
% decrease = 72.2%
Average attendance in 2003 = 1800
Average attendance in 2004 = 500
Decrease in attendance = 1800 - 500 = 1300
Decrease percentage in attendance
[tex] = \frac{1300}{1800} \times 100[/tex]
[tex] = \frac{13}{18} \times 100[/tex]
[tex] = \frac{13}{9} \times 50[/tex]
=72.22
