Probablity=desiredoutcomes/totalpossible
total possible=number of cards or number of letters which is 8 letters
desired is number is the letter "I", which is 3
3/8 is probality
in favor it is 3:5, because we are looking at odds of picking vs not picking
not is 5/8
3:5 s answer
A is answer
5 and 3/5 is 5.75 as a decimal
Answer:
- m = 4/3; b = -4
- m = 3; b = -6
Step-by-step explanation:
In each case, <em>solve for y</em>. You do this by getting the y-term by itself, then dividing by the coefficient of y.
<h3>1.</h3>
-3y = -4x +12 . . . . . subtract 4x
y = 4/3x -4 . . . . . . . divide by -3
The slope is 4/3; the y-intercept is -4.
__
<h3>2.</h3>
y = 3x -6 . . . . . . divide by 2
The slope is 3; the y-intercept is -6.

<em>Additional comment</em>
Whatever you do to one side of the equation, you must also do to the other side. When we say "subtract 4x", that means 4x is subtracted from both sides of the equation. The reason for doing that in the first equation is to eliminate the 4x term from the left side.
(Sometimes, you may see operations described as "move ...". There is no property of equality called "move." There are <em>addition</em>, <em>subtraction</em>, <em>multiplication</em>, <em>division</em>, and <em>substitution</em> properties of equality. Any equation solving process will make use of one or more of these.)
A sailboat travels 3 miles in 1.5 hours. How far does it travel in 2 hours.
= 3 miles / 1.5 hours
= 2 miles per hour
= (2 miles) * (2 hours)
= 4 miles in 2 hours.
So, in conclusion, if a sailboat travels 3 miles in 1.5 hours, it travels 4 miles in 2 hours.
To determine x intercept get y=0 then substitute in equations: y=6x-11
0=6x-11 then x= 11/6
To determine y intercept get x=0 then substitute in equations: y=6x-11
y=6(0)-11 then y=-11
