Answer:
Step-by-step explanation:
Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.
Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :
2x - y = 2
4x - 2y = 8
put both equations in slope intercept form
y = 2x - 2
y = 2x - 4
they both have the same slope of 2.....and the y intercepts are different....meaning they are parallel lines and have no solutions
Because the left side sqrt is multiplied by 3 if it was just added it would be correct because it would cancel out and leave the 3’s. Since it’s multiplied it would change the value
Answer:
Step-by-step explanation:
10,12,13,20, 21,
Answer:
5 ft and 11 ft
Step-by-step explanation:
l= 2w+1
A=lw= 55
w(2w+1)=55
2w²+w-55=0
integer solution of quadratic equation is:
w=5 ft
l= 2*5+1=11 ft
