Answer:
Step-by-step explanation:
The given equation of a parabola is,
When we compare this equation with the vertex form of the quadratic equation,
y = a(x - h)² + k
where (h, k) is the vertex,
Vertex of the parabola,
(-3, 4)
y-intercept,
x-intercepts,
(x + 3) = ±√8
x = (3 - 2√2), (3 + 2√2)
Axis of symmetry,
x = -3
Domain:
(-∞, ∞)
Range:
(-∞, 4]
This equation is not correct. Because,
And
The only possible, solution for this equation would be, x=0. Because,
for x=0 :
Answer:
see below
Step-by-step explanation:
9 is the difference of a number n and 7.
Let's break this down.
"is" represents the equal sign.
"the difference" represents subtraction.
9 = n - 7
Now let's solve the equation.
9 = n - 7
Add 7 to both sides.
16 = n
Hope this helps!
Answer:
300%
Step-by-step explanation:
By increasing the down payment from 1,000 to 4,000, how does the total purchasing cost change?
If down payment is increased from 1000 to 4000
Icecrement = 4000-1000
Increment =3000
Percentage increase = 3000/1000×100
Percentage increase = 3000/10
Percentage increas=300%
