M(x) = 5x + 4 n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
= 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
= 30x - 45 + 4
= 30x - 41

What are the coordinates of the y-intercept of the line who's equation is 12x + 13y =8???

Ierofanga [76]

Answer:

y-intercept = (0, $\frac{8}{13}$ ).

Step-by-step explanation:

Given the linear equation in standard form, 12x + 13y = 8:

We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.

12x + 13y = 8

Subtract 12x from both sides:

12x + 13y - 12x = - 12x + 8

13y = - 12x + 8

Next, divide both sides of the equation by 13 to solve for y:

$\frac{13y}{13} = \frac{-12x + 8}{13}$

$y = \frac{-12x + 8}{13}$ or $y = -\frac{12}{13} x + \frac{8}{13}$

Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is the point where the graph of the linear equation crosses the y-axis).

Let x = 0:

$y = -\frac{12}{13} x + \frac{8}{13}$

$y = -\frac{12}{13} (0) + \frac{8}{13}$

$y = \frac{8}{13}$

Therefore, the value of y when x = 0 is $\frac{8}{13}$ . This is the y-intercept, and its coordinate is (0, $\frac{8}{13}$ ).

Evalua 6+x cuando x=3

Gala2k [10]

Answer:

6+3=9

Step-by-step explanation:

Evaluando 6+3=9, porque tu tienes que intercambiar x por 3 porque x es 3. Después tu tienes que buscar tu repuesta. Disculpa mi español no es tan bueno escribiendo
