The percent change from $10 to $27

1 answer:

4 0

→ $\frac{(27-10)}{|10|}$ × 100

→ $\frac{17}{10}$ × 100

→ 1.7 × 100 = 170

→ So, that means the change is → 170% ←

The midpoint of overline AB is M(2, -2) If the coordinates of A are (-2, 1), what are the coordinates of B?

Tju [1.3M]

Answer:

(6, -5)

Step-by-step explanation:

Midpoint :

(2, -2) = (x - 2 / 2, y + 1 / 2)

Equations formed :

x - 2 / 2 = 2

x - 2 = 4
x = 6

2. y + 1 / 2 = -2

y + 1 = -4
y = -5

Coordinates of B : (x, y)

(6, -5)

What is the value of the equation f(x) =2x -3x +7 when x equals 2

Ber [7]

Answer:

Step-by-step explanation:

f(x) = 2x - 3x + 7

Plug in 2 every time you see an x within the equation: x = 2

f(2) = 2(2) - 3(2) + 7

f(2) = 4 - 6 + 7

f(2) = -2 + 7

f(2) = 5

Given the functions ƒ(x) and g(x), which of the following statements is true? x -2 -1 0 1 2 ƒ(x) -3 3 5 3 -3 g(x) = -x2 + 4x ƒ(x

Morgarella [4.7K]

Answer:

The correct option is 1.

Step-by-step explanation:

From the given table is notices that the function f(x) is a downward parabola.

The maximum value of f(x) is 5 at x=1.

The function g(x) is

$g(x)=-x^2+4x$

vertex of the parabola is

$(\frac{-b}{2a}, g(\frac{-b}{2a}))$

$(\frac{-4}{2\times 1}, g(\frac{-4}{2\times 1})$

$(2, g(2))$

Put x=2.

$g(x)=-2^2+4(2)=4$

Therefore the vertex of g(x) is (2,4). The vertex of a downward parabola is the maximum point of the function.

Therefore ƒ(x) has the greater maximum. Option 1 is correct.
