Find the equation of the straight line passing through the point (3,3) which Is perpendicular to the line y=-1/2 x+4

Nataly [62]

Answer:

y = 2x - 3.

Step-by-step explanation:

The perpendicular line will have slope - 1 / -1/2 = 2.

Using the point-slope form of the straight line:

y - y1 = m(x - x1)

Here m = 2 and (x1, y1) = (3, 3) so we have:

y -3 = 2(x - 3)

y = 2x - 6 + 3

y = 2x - 3.

Factor this trinomial completely.

WITCHER [35]

Answer:

Option C. (2x+3)(6x – 5) is the correct answer.

Step-by-step explanation:

Given polynomial(trinomial) is:

$12x^2 + 8x - 15$

The given trinomial is quadratic. Factorization will be as follows:

Multiplying the co-efficient of x^2 and the constant results in 180. We have to make factors of 180 in such a way that their sum of difference is equal to the co-efficient of x.

The required factors are 18 and 10

So,

$=12x^2+18x-10x-15\\=6x(2x+3)-5(2x+3)\\= (6x-5)(2x+3)$

Hence,

Option C. (2x+3)(6x – 5) is the correct answer.
