Answer:
b=-3
Step-by-step explanation:
4b+3=-9
-3 -3
subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.
4b=-12
youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4
4b/4=-12/4
4b divided by 4 is 1. -12 divided by 4 is -3
b=-3
plug -3 in for b to make sure its correct
4(-3)+3=-9
-12+3=-9
-9=-9
<em>1.) </em><em>1</em>
<em>Let's start with 18 degrees and then subtract 12 degrees from it</em>
<em>18-12=6</em>
<em>Now let's take 6 degrees and subtract 5 from it</em>
<em>6-5=</em><em>1</em>
<em>At 2 pm the temperature was 1 degree.</em>
<em>2.) </em><em>$125</em>
<em>Start with the total amount John had ($250) and then subtract his remaining amount ($125) to find out how much he withdrew.</em>
<em>$250-$125=</em><em>$125</em><em> </em>
Convert to slope / intercept form:-
4x + 5y = -2
5y = - 4x - 2
y = -4/5 x - 2/5
the slope of this line is -4/5 and slope of line perpendicular to it is - 1 / -4/5
= 5/4 answer
The answer would be: It is 15% more likely to be delayed.

The table should look like this:
Good weather Bad Weather
Delayed 7.5% 17.5%
On Time 42.5% 32.5%
The question is asking whether the probability when "bad weather" and "on time" more likely than "On time". So, you need to find the difference between them. The calculation would be:32.5%- 17.5%= 15%</span>
C=50h+25
C=50(8)+25
C=400+25
C=$425
C=50(10)+25
C=500+25
