What are the Solutions to the system of equations?

mamaluj [8]

Answer:

Step-by-step explanation:

to find the "solution" to this system, set f=g.

then we get: $f(x)=g(x)=2x+1=x^2+2x-8$

$=x^2-9=(x+3)(x-3)\\\\x=-3,3\\$

plugging in 3,-3 for x in both equations, we get:

(3,7),(-3,-7),(-3,-5)

Andrew is 50 years younger than Natasha. 6 years ago, Natasha's age was 3 times Andrew's age. How old is Andrew now?

jok3333 [9.3K]

Natasha's age is 81 years and Andrew's age is 31 years

Step-by-step explanation:

Step 1: From the given details, let the age of Natasha be x, then age of Andrew is x - 50.
Step 2: Form equations out of their details of ages 6 years ago.

⇒ x - 6 = 3(x - 50 - 6)

⇒ x - 6 = 3(x - 56)

⇒ x - 6 = 3x - 168

⇒ 2x = 162

⇒ x = 81

Step 3: Calculate Andrew's age

x - 50 = 81 - 50 = 31
