(i) The highest degree of x

2

+x is 2, so it is a quadratic polynomials.

(ii) The highest degree of x−x

3

is 3, so it is a cubic polynomials.

(iii)The highest degree of y+y

2

+4 is 2, so it is a quadratic polynomials.

(iv) The highest degree of x in (1+x) is 1, so it is a linear polynomials.

(v)The highest degree of t in 3t is 1, so it is a linear polynomials.

(vi)The highest degree of r

2

is 2, so it is a quadratic polynomials.

(vii)The highest degree of x in 7x

3

is 3, so it is a cubic polynomials.

The slope of the line below is -2. Use the coordinates of the labeled point to
nika2105 [10]

Answer:

y + 6 = -2(x - 4)

Step-by-step explanation:

Given:

Slope (m) = -2

Point on the line = (4, -6)

Required:

Point-slope equation of the line

Solution:

Point-slope equation takes the following form:

y - b = m(x - a),

Where,

m = slope of the line = -2

(a, b) = coordinates of the point on the line. = (4, -6)

Plug in the values into the slope-point equation

y - (-6) = -2(x - 4)

y + 6 = -2(x - 4)

The present age of the mother is 30 years.

<u>Step-by-step explanation</u>:

Step 1 :

At present,

  • Age of Jane = x
  • Age of Billy = 5x
  • Age of mother = 3(5x) = 15x

Step 3 :

After 2 years,

  • Age of Jane = x+2
  • Age of mother = 8 times as Jane = 8(x+2)

Step 3 :

Age of mother at present + 2 years = Age of mother after 2 years

⇒ 15x + 2 = 8(x+2)

⇒ 15x + 2 = 8x + 16

⇒ 7x = 14

⇒ x = 2

Step 4 :

Substitute x=2,

Age of mother at present = 15x = 30 years.

(x^2 - 3x - 10)(x + 4)
= (x - 5)(x + 2)(x + 4)

so the zeroes are (5,0), (-2,0) and (-4,0)
