The answer is C because is n is positive and even it will only open up.
Y = (2/3)x + 6
3y - 5x = 9
find an expression for y from the second equation:-
y = (5/3)x + 3
Now substitute this for y in the first equation:-
(5/3) x + 3 = (2/3)x + 6 Now solve for x:-
(5/3)x - (2/3)x = 6 - 3
x = 3
Now plug x = 3 into the second equation to find the value of y:_
3y - 5(3) =9
3y = 15+9 = 24
y = 8
So the solution is x = 3, y = 8
written as a set this is {3,8}.
Answer:
The value of height of the building h = 509.2 feet
Step-by-step explanation:
From the Δ A B C

⇒ h = y
° ------- (1)
From Δ A B D

⇒ h = ( y + 300 )
° ------- (2)
Equation 1 = Equation 2
⇒ y
° = ( y + 300 )
°
⇒ 0.46 y = 0.36 y + 109.2
⇒ 0.1 y = 109.2
⇒ y = 1092 feet
Put this value of y in equation ( 1 ) we get,
⇒ h = 1092 × tan 25°
⇒ h = 509.2 feet
This is the value of height of the building.
