Five years ago I was 5 times older than my son. In 8 years’ time I will be 3 times older than my son. How old am I today?
o-na [289]

Let x = Parent's age now  y = son's age now

Then, x-5 = parent's age five years ago

        y-5 = son's age five years ago

     So, x-5 = 5(y-5)

          Simplify to get x - 5y = -20

Parent's age 8 years from now = x+8

Son's age 8 years from now = y+8

    So, x+8 = 3(y+8)

           Simplifying, we have x - 3y = 16

We have the system of equations:  x - 5y = -20

                                                  x - 3y = 16

Subtract the equations to obtain -2y = -36

                                                  y = 18

                                                  x = 70

Parent is 70 years old and the son is 18 years old.

Answer:

B.   60x^8

Step-by-step explanation:

4x^2\sqrt{5x^4} \cdot 3\sqrt{5x^8} =

= 4x^2 \times 3 \sqrt{5x^4 \times 5x^8}

= 12x^2 \sqrt{25x^{4+8}}

= 12x^2 \sqrt{25} \sqrt{x^{12}}

= 12x^2 \times 5 \times x^6

= 60x^8

PLEASE ANSWER ITS DUE SO SOON
geniusboy [140]

the line is negative because it goes down as you move right

slope = rise/run = 4/2 = 2

y = 2x+b

use a point on the line - I picked (-4, 3)

3 = 2(-4)+b

3 = -8+b

11 = b

<h2>y = 2x +11</h2>
