Answer:
The time required them working together to shovel the snow is T = 1.428 hours
Step-by-step explanation:
Given data
Time taken by first person to shovel the snow 
= 2 hours
Time taken by second person to shovel the snow 
= 5 hours
Time taken by both persons to shovel the snow
Put all the values in above equation we get
T = 1.428 hours
Therefore the time required them working together to shovel the snow is T = 1.428 hours
Find the axis of symmetry.
x= 1/2
Answer:
Undefined
Step-by-step explanation:
Ok so lets say we have a system of equations:
y = x + 1
x + y = 5
All you would do is plug in what is equal to the variable so:
x + x + 1 = 5
Then you would just simplify and solve
2x + 1 = 5
-1 -1
_________
2x = 4

2 2
x=2
The small right angled triangle with hypotenuse vale 5 is similar to the big triangle with b as the hypotenuse
Corresponding sides are in the same ratio so we can write
a/12 = 5/b.....(1)
Also applying pythagoras theorem to the large triangle
b^2 = 5^2 + 12^2
b^2 = 169
b = 13
So substituting in equation (1):-
a / 12 = 5 / 13
a = (5*12 ) / 13
