Mathematics

Answer:

Just try to make it make sense to you.

Step-by-step explanation:

For instance, a + 1 = 5

a = 4

We know that we should switch the terms as when it comes to normal numbers ,10 + 1 = 11 , 10 = 11-1. Therefore, the only trick is not to memorise, but try to understand the logic behind it. Hope this helps in some way???

At present a man is 5 times as old as his son, in 13 years time he will be three times as old as his son. Find the man's present
Yuliya22 [10]

Answer:

65

Step-by-step explanation:

let the son's age be x then the man's age is 5x

In 13 years

son's age = x + 13 and man's age = 5x + 13 and he is 3 times as old as son

5x + 13 = 3(x + 13)

5x + 13 = 3x + 39 ( subtract 3x from both sides )

2x + 13 = 39 ( subtract 13 from both sides )

2x = 26 ( divide both sides by 2 )

x = 13 ← son's present age

5x = 5 × 13 = 65 ← man's present age

Give the domain and range of the relation.<br> y=(x+4)^2-4
Westkost [7]

Answer:

The domain is the interval  (-∞,∞)

The range is the interval [-4,∞)

Step-by-step explanation:

we have

y=(x+4)^2-4

This is the equation of a vertical parabola in vertex form

The vertex is the point (-4,-4)

The parabola open upward (because the leading coefficient is positive)

The vertex represent a minimum

The domain is the interval  (-∞,∞)

so

The domain is all real numbers

The range is the interval [-4,∞)

y\geq -4

so

The range is all real numbers greater than or equal to -4
