The graph of the function is f(x)= x2 − 4x + 6 . What is its axis of symmetry?

1 answer:

8 0

To find the axis of symmetry you must first find the vertex of the parabola. The formula for vertex is -b/2a. So the vertex has a "x" coordinate at 4/2 or 2. so the axis of symmetry is the vertical line x = 2

Juan went out to eat dinner, and the meal cost $60.00. If Juan received an 18% discount, what was the total value of the discoun

DaniilM [7]

Answer:

The total value of the discount was $10.80.

Step-by-step explanation:

Since we are finding the value of the discount, we just need to find 18% of 60.

We can convert 18% into a decimal.

18%=0.18

Multiply.

0.18*60=10.8

The total value of the discount was $10.80.

Which ordered pair would form a proportional relationship with the point graphed below? (60,-20)

valentina_108 [34]

Given:

The graphed point is (60,-20).

To find:

The ordered pair that would form a proportional relationship with the given point.

Solution:

If y is proportional to x, then

$y\propto x$

$y=kx$

$\dfrac{y}{x}=k$

Where, k is the constant of proportionality.

For the given point,

$k=\dfrac{-20}{60}$

$k=\dfrac{-1}{3}$

For option (A),

$k=\dfrac{30}{-10}$

$k=-3\neq \dfrac{-1}{3}$

For option (B),

$k=\dfrac{-15}{30}$

$k=-\dfrac{1}{2}\neq \dfrac{-1}{3}$

For option (C),

$k=\dfrac{10}{-30}$

$k=\dfrac{-1}{3}$ .

The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.

Therefore, the correct option is C.

Gerry expands her square garden by 35 inches along its width.The area of the new garden can be found with the function below whe

muminat

Given that the initial dimension of the square garden is x, the initial area would become x². When any of the dimension is increased by 35 inches then, the area is increased by 35x. The statement that describes 35x is the additional area of the figure after it was extended for 35 inches.
