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.

Write a quadratic equation in the form ax^2+bx+c=0 with roots of -4 and 5

Stolb23 [73]

Step-by-step explanation:

- 4 & 5 are roots

Therefore, (x + 4) & (x - 5) are factors.

Required quadratic equation is given as:

$(x + 4) (x - 5) \\ = x(x - 5) + 4(x - 5) \\ = {x }^{2} - 5x + 4x - 20 \\ = {x}^{2} - x - 20 \\$
