Step-by-step explanation: Think of a translation as just sliding a figure.

So here, we will move each of the points 1 unit to the left.

Take a look below.

On the new figure translate I used the ' next to the letters.

That means "prime" which shows that we changed its location.

Make sure to use that on the new translation!

Answer:

$\displaystyle (-∞, 2\frac{1}{3}) ∪ (1, ∞) \\ \\ 2\frac{1}{3} > t \:OR\: 1 < t$

Step-by-step explanation:

3t + 2 < 7 OR −4t + 5 < 1

- 2 - 2 - 5 - 5

___________________

$\displaystyle \frac{3t}{3} < \frac{7}{3} \:OR\: \frac{-4t}{-4} < \frac{-4}{-4} \\ \\ t < 2\frac{1}{3} \:OR\: t >1$

To find the area of a triangle, you have to multiply the height and the base length, and divide that by two.

In this question, the height is 3 square units and the base length is 4 square units.

Therefore, to find the area, you must multiply 3 by 4, which is 12, and then divide this by 2, which is 6.

So the area of this triangle is 6 square units.

Which part of an ecuation is the sum

erastova [34]

All parts of arithmetic equations have names. In an addition equation, addends are the numbers that are added together to give a sum. In a subtraction equation, the subtrahend is taken away from the minuend to give a difference. In a multiplication equation, factors are multiplied to give a product.
