Answer and Step-by-step explanation:
is the equation to find the axis of symmetry of a quadratic equation.
-3 = a
18 = b
10 = c
Now we plug the values into the equation.
The axis of symmetry is on the line x = 3.
#teamtrees #WAP (Water And Plant)
#2 is 1 and 2 is both 78%
I assume the equation is
√(2x - 5) - √(x + 6) = 0
Note the domains for the root expressions:
• √(2x - 5) : 2x - 5 ≥ 0 ⇒ x ≥ 5/2
• √(x + 6) : x + 6 ≥ 0 ⇒ x ≥ -6
So any valid solution we find must be at least 5/2.
Move one term to the other side.
√(2x - 5) = √(x + 6)
Take squares.
(√(2x - 5))² = (√(x + 6))²
2x - 5 = x + 6
Solve for x :
x = 11
Answer:
b

Answer:
h = 7 1/2
Step-by-step explanation:
2/5 h = 3
Multiply each side by 5/2 to isolate h
5/2 * 2/5 h = 5/2 *3
h = 15/2
h = 7 1/2
