Translate point A (2,5) 4 to the rt and up 3 what are the new coordinates

Karolina [17]

Answer:

The new coordinates of the point are (6, 8)

Step-by-step explanation:

Suppose we have a point (x, y)

Let's define the translations:

For a positive number N:

A translation of N units to the right is written as (x + N, y)

A translation of N units to the left is written as (x - N, y)

A translation of N units upwards is written as (x, y + N)

A translation of N units down is written as (x, y - N)

Then if we have the point (2, 5) and we want to translate it 4 units to the right, the new point will be (2 + 4, 5) = (6, 5)

And now we want to do a translation of 3 units up, then the new point is (6, 5 + 3) = (6, 8)

The new coordinates of the point are (6, 8)

Jane is 5 times older than her sister. In 3 years, Jane’s sister will be 1/4 her age. Find the ages now

Korolek [52]

The present age of Jane is 45 years old and present age of her sister is 9 years old

Solution:

Let the present age of Jane be "x"

Let the present age of her sister be "y"

Jane is 5 times older than her sister

present age of Jane = 5(present age of her sister)

x = 5y ---------- eqn 1

In 3 years, Jane’s sister will be 1/4 her age

Age of sister after 3 years = 3 + y

Age of jane after 3 years = 3 + x

Age of sister after 3 years = 1/4(age of jane after 3 years)

$3 + y = \frac{1}{4}(3 + x)$

Substitute eqn 1 in above equation

$3 + y = \frac{1}{4}(3 + 5y)\\\\12 + 4y = 3 + 5y\\\\5y - 4y = 12 - 3\\\\y = 9$

Substitute y = 9 in eqn 1

x = 5(9)

x = 45

Thus present age of Jane is 45 years old and present age of her sister is 9 years old

Zoey goes to a store an buys an item that costs x dollars. She has a coupon for 15% off, and then a 9% tax is added to the disco

pshichka [43]

Answer:

0.9265x

Step-by-step explanation:

x - 0.15x + 0.09(0.85x)

x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.

Simplified:

x - 0.15x + 0.09(0.85x)

= 0.85x + 0.0765x

= 0.9265x
