Both these expression are written in slope-intercept form. y = mx + b
m = slope
b = y-intercept
We can find the slope of each expression by finding what m is in each equation.
y = -3x + 2 -> m = -3
y = 4x - 5 -> m = 4
Remember that m = slope

Answer: 4
<u>Step-by-step explanation:</u>
To fit the maximum amount of people in one row, you would have 3 couples and 1 single = 7 parents.
If we continue the maximum amount of people for 7 rows, we get 49 parents seated.
Since a total of 54 parents are seated, that leaves 54 - 49 = 5 parents remaining to be seated in the last row. These parents can be seated as 2 couples and 1 single. If you put the single at the end of the row, there will be 4 seats between the couple and the single.

Answer:
B and D
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3 , since
- 4 × 3 = - 12 and - 4 + 3 = - 1 , then
x² - x - 12 = (x - 4)(x + 3) ← in factored form
Answer:
Step-by-step explanation:
Given
Red = 5
Blue = 3
Orange = 2
Required
Probability that the first marble is Blue
First, the total number of marble has to be calculated;
The probability of Blue being the first is calculated as thus;
<em>Hence, the required probability is 0.3</em>
