less than 3 is a 1 or 2
probability of 1 or probability of 2
1/8 + 1/8
2/8
= 1/4
Answer: 1/4 = .25
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have:
.
Substitute:
Therefore we have 
.
Substitute the coordinates of the point (1, 1) to the equation:
<em>add 3 to both sides</em>
<h3>Answer: y = -3x + 4</h3>
We have:
Substitute:
Therefore we have 
.
Substitute the coordinates of the point (4, 1) to the equation:
<em>subtract 3 from both sides</em>
<h3>Answer:
</h3>
Answer:
He got $25 in change.
Step-by-step explanation:
Suppose the balance amount is x.
The cost of 3 pants is 3 × 25 = 75
John paid = $ 100
x = 100 – 75
x = 25
Answer:
3:2
Step-by-step explanation:
You have to divide both sides by the <u>same </u>number
Answer:
-1 x - 2
f (x) = -----------
3
Step-by-step explanation:
Then we have y = 3x + 2.
Next, interchange x and y, obtaining x = 3y + 2
Next, solve this result for y: 3y = x - 2; then divide both sides by 3:
y = (x-2)/3
Last, replace "y" with the inverse function label:
-1 x - 2
f (x) = -----------
3
