To Find :
The equation of the quadratic whose Vertex is at ( −4,−5) and passes through the point (−3, −7).
Solution :
A quadratic equation in vertex form is given by :
( Here, h, k is the vertex )
y = a(x-(-4))² + (-5)
y = a(x+4)² - 5
Now, putting (-3,-7) in above equation:
-7 = a( -3 + 4 )² - 5
a(1)² = -2
a = -2
Therefore, the equation of the quadratic is y = -2(x+4)² - 5 .
Answer:
The solution to the equation is x = 0.
Step-by-step explanation:
Hi there!
First, let´s write the equation:
3/(√x+3)=1
To solve the equation, let´s start multiplying both sides by (√x+3)
3 = √x+3
subtract 3 to both sides of the equation
0 = √x
0 = x
Now, let´s check the solution:
3/(√x+3)=1
x = 0
3/(√0 + 3) = 1
3/3 = 1
1 = 1
Then, x = 0 is the solution to the equation.
