Arlecino [84]

Answer:

24x^4+18x^3-15x^2 -42x-24

Step-by-step explanation:

(6x^2-3x-6)(4x^2 +5x+4)=

6x^2*4x^2 +6x^2*5x+6x^2*4

-3x*4x^2 - 3x*5x-3x*4

- 6*4x^2 -6*5x-6*4=

24x^4+30x^3+24x^2-12x^3-15x^2 -12x

-24x^2-30x-24=

24x^4+18x^3-15x^2 -42x-24

Anvisha [2.4K]

Answer:

(0, 7)

Step-by-step explanation:

The point that crosses the y-axis is called the y-intercept of the line.

We are given an equation of the line and we need to determine the y-intercept. This can be done by determining the constant in the equation.

What are constants?

Constants are such terms that include only numbers. There should be no variables in constants.

<u>We know that:</u>

     \bullet \ \text{Given equation of line: y = 5x + 7}

The constant we can see in the equation is "7". Therefore, the y-intercept is 7.

Note: The y-intercept of the line must have an x-coordinate of 0.

<u>Therefore,</u>

⇒ Coordinates of y-intercept: (x, y) ==> (0, 7).
