Product of odd numbers is an odd number.
Answer:
(a) 2x + 4y ≥ 3 ; 2x + 4y ≤ 3
Step-by-step explanation:
When inequalities are involved, the resulting solution is generally a region since for a value of x, we have y greater than or less than a particular value and vice versa.
When a system of equations with inequalities are solved, the intersection of all the equations in the system is the solution.
In the first option, we see that the both equations have 2x+4y=3 as common. So, it is the solution of the first system of inequalities.
Similarly, the solution of second system of inequalities is 2x+4y>3 and the third system is none since they don't intersect at all.
Here, 2x+4y > 3 denotes a region and 2x+4y=3 is the equation of a straight line.
Hence the first system has a solution that is a line.
Answer:
Option A
Step-by-step explanation:
Given data
We are told that the weight of the rabbit is 2.8 kilograms
We also want to convert from kilograms to grams
We know that 1kg= 1000 grams
Hence 2.8 kg= x gram
Cross multiply
x= 2.8*1000
x= 2800 grams
Hence the weight in grams is 2800grams
Option A is correct
Step-by-step explanation:
Given
7x + 1 = 9x - 7
9x - 7x = 1 + 7
2x = 8
x = 8 / 2
x = 4
