Explain how you would get the answer please

To find the intersection points, you take x^2 - 4x + 9 = -2x + 17

This gives x^2 - 2x - 8 = 0,

which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2

From the graph, we can see that x is positive, meaning x = 4, so a = 4.

Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.

a + b = 4 + 9 = 13. The answer is B.

El ingreso de una empresa de construcción de obras civiles se estima a través del tiempo de acuerdo con la siguiente función I(t

brilliants [131]

Usando conceptos de funciones cuadráticas, se encuentra que:

El máximo ingreso será alcanzado en 6 años.

El máximo ingreso será de 800 miles de soles.

La función que estimate el tiempo es dada por:

$I(t) = -64 + 288t - 24t^2$

Que es una función cuadrática con coeficientes $a = -24, b = 288, c = -64$ .

El año en qué se alcanzará el máximo ingreso es el <u>valor de t de el vertice</u>, o sea:

$t_V = -\frac{b}{2a} = -\frac{288}{2(-24)} = \frac{288}{48} = 6$

El máximo ingreso será alcanzado en 6 años.

El valor del máximo ingreso es el valor de <u>I de el vertice</u>, o sea:

$I_v = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}$

Entonces:

$I_v = -\frac{288^2 - 4(-24)(-64)}{4(-24)} = 800$

El máximo ingreso será de 800 miles de soles.

Answer:

A

Step-by-step explanation:

Here, we want to find the value farthest to the right here.

What this means is that we want the value that is most positive. The values farthest to the right side are the most positive;

A is 10-(-7) = 17

B is 3

C is -17

D is -3

The value farthest to the right is 17 which is A and it is the most positive value
