Dotty is 51 years old and esmerelda is 23. how many years ago was dotty 3 times esmerelda's age?

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)

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
