Mathematics

kari74 [83]3 years ago
3 0

Answer:

9 years ago.

Step-by-step explanation:

Dotty is 51 years old and Esmerelda is 23 now.

Now, x years ago the age of Dotty was (51 - x) years and the age of Esmerelda was (23 - x) years.

Assume that x years ago Dotty was 3 times Esmerelda's age.

So, we can write the equation as

3(23 - x) = 51 - x

⇒ 69 - 3x = 51 - x

⇒ 69 - 51 = 3x - x

⇒ 18 = 2x

⇒ x = 9 years.

Therefore, 9 years ago Dotty was 3 times Esmerelda's age. (Answer)

Consider the functions. F(x)=(x+1)2-4 and g(x)=-4|x+1| which statement compares the range of the functions?
Andreyy89

Answer:

<h2>        The fourth</h2>

Step-by-step explanation:

Vertex of f is (-1, -4) so its range is limited to y≥-4

|x+1| is always ≥0 therefore -|x+1| is always ≤0 {4 is insignificant to this - slope doesn't mean in range} so its range is limited to y≤0
