Answer:

Y intercept will be -4.

Step-by-step explanation:

Here we are given our function as

2y+8=6x^2-10x

We are asked to determine the y intercept.

The y intercept is the y ordinate of the coordinates of the point at which the graph of the function intersects the y axis.

Please note that the point at which graph cuts the y axis have x=0

Hence in order to determine y intercept we need to put x=0 in our function and solve it for y :

2y+8=6x^2-10x2y+8=6x^2-10x

Putting x =0

2y+8=6x^2-10x2y+8=6(0)^2-10(0)

2y+8=6x^2-10x2y+8=0-10(0)

2y+8=6x^2-10x2y+8=0

subtracting both sides by 8

2y+8=6x^2-10x2y=-8

dividing both sides by 2

=-4

Does the point (1, –9) satisfy the equation y = 3x − 6?
Tju [1.3M]

Answer:

No.

Step-by-step explanation:

Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.

y = 3x - 6

-9 = 3 * 1 - 6

-9 = 3 - 6

-9 = -3.

So, the points (1, -9) does not satisfy the equation y = 3x - 6.

Find the equivalent expression of the following: x3 (x2 + 5x + 7)
Kay [80]

The equivalent expression of x^3 (x^2 + 5x + 7) is x^5 + 4x^4 + x^4 + 8x^3 - x^3

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

x^3 (x^2 + 5x + 7)

Expand the expression

x^3 * x^2 + x^3 * 5x + x^3 * 7

Evaluate the product

x^5 + 5x^4 + 7x^3

Expand the expression

x^5 + 4x^4 + x^4 + 8x^3 - x^3

Hence, the equivalent expression of x^3 (x^2 + 5x + 7) is x^5 + 4x^4 + x^4 + 8x^3 - x^3
