Answer:
2nd and 5th options
Step-by-step explanation:
the solution to a system of equations is at the point of intersection of the 2 lines.
If the lines are parallel then they never intersect and will have no solution.
The slopes m of parallel lines are equal.
The options with equal slopes , both - 2 are the
2nd and 5th options
Answer:
23ft approx
Step-by-step explanation:
Given data
Distance from tree= 10ft
Length of ladder= 25ft
We can find the height of the tree by applying the Pythagoras theorem
z^2= x^2+y^2
z= The height of the ladder
x= The distance from the tree
y= The height of the tree
25^2= 10^2+ y^2
625=100+y^2
625-100=y^2
525=y^2
y= √525
y= 22.91
Hence the height of the tree is 23ft approx
It’s the last one. Six.
