konstantin123 [22]

Answer:

y = \sqrt{\frac{x-3}{3} }

Domain = [3, infinity)

Step-by-step explanation:

x = 3y^2 + 3

3y^2 = x - 3

y^2 = (x-3)/3

y = \sqrt{\frac{x-3}{3} }

2x^2+7x=15 write in standard then factor the left side of the equation.
Nataly [62]

Answer:

see explanation

Step-by-step explanation:

Given

2x² + 7x = 15 ( subtract 15 from both sides )

2x² + 7x - 15 = 0 ← in standard form

To factorise the left side

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 15 = - 30 and sum = + 7

The factors are + 10 and - 3

Use these factors to split the x- term

2x² + 10x - 3x - 15 ( factor the first/second and third/fourth terms )

2x(x + 5) - 3(x + 5) ← factor out (x + 5) from each term

(x + 5)(2x - 3) ← in factored form

The ratio of the measures of all three angles in a triangle is 14:5:11. Find the measures of the angles.
Maru [420]

Answer:

30, 66 and 84 degrees.

Step-by-step explanation:

The number of degrees in a triangle is 180 degrees.

Work out the 'multiplier':

It = 180 / (14+5+11)

= 180/30

= 6.

So the angles are:

14*6 = 84

5*6  = 30

11*6  = 66.
