Answer:
1. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Step-by-step explanation:
Answer:
g=-7x-1/x
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Well the slope is y = -3/2x and B is the only option with that slope.
Answer:
(a) and (f)
Step-by-step explanation:
Given
See attachment for table and options
First, we calculate the slope of the table
Using:
So, we have:
The equation is then calculated using:
This gives:
So, we have:
--- The given equation
and
--- The equation of the table
An equation is represented as:
Where:
m = slope or rate of change
b = y intercept
So, for the given equation:
Rate of change = 5
y intercept = 12
For the table:
Rate of change = 12
y intercept = 5
In conclusion:
(a) has the greater rate of change:
and
(f) has the greater y intercept
Option B. 12/ 125 is the answer.
Explanation
Total umber of sour ball candies = 50
Number of lemon candies = 12
Hence the probability to get a lemon candy is = 12/50
Number of cherry sour balls = 20
So, the probability to get a cherry sour ball = 20/50
So, to get the joint probability for a random selection to either get a lemon or cherry candy, we will multiply both the probabilities.
