Answer:
Lines A and B form a consistent independent system
Step-by-step explanation:
we know that
A consistent system of equations has at least one solution
In this problem
The system of Line A and Line B has only one solution, since it has only one point of intersection.
and the Line A is different to Line B
therefore
Lines A and B form a consistent independent system
(independent because Lines A and B are different)
Answer:
2) 160
3) 320
Step-by-step explanation:
you want to find out the slope so use the formula
y₂-y₁/ x₂-x₁ and plug in the numbers
320-80=240
4-1=3
divide 240/3= 80
multiply 80 * (x) so if we try and find x=2 it would be 160
80 * 3 = 240
check your work by multiplying 80 and 4 (320) which is your y value! hope this helps!
The answer is 6*square rooted*2
Answer: 
Step-by-step explanation:
Given
Rectangle has an area of 
Suppose rectangle length and width are 
and 
If each side is increased by 
Area becomes 
We can write
Substitute the value of width from (ii) in equation (i)
Width corresponding to these lengths
Therfore, we can write the length of the longer side is
