I believe your answer is:

(4,7)

Here’s why:

I have graphed the system on a program.
The two lines intercept at the point (4,7). This means that it is the solution to the system.

Hope this helps you. I apologize if it’s incorrect.

What would the measurement at the top be?

Answers

Hopes this helps please correct me if I am wrong:

Answer: 6cm

6cm, the reason for that is because of the invisible line that says 6cm if that line is the same length as the top; which it is, it would also be 6cm

So in conclusion the answer would be 6cm.

Hope this helps! Have a good one!❤️

Question 8A rectangle has vertices at (0,0), (3,0), and (0,6). What is the area
of the rectangle?

I’ll mark you!

Answers

Answer:

18 square units

Step-by-step explanation:

The area of a rectangle is simply it's base length multiplied by its height.

A = b × h

Since a rectangle has all right angles, it must have two sets of parallel sides.

Given the coordinates (0, 0), (3, 0), (0, 6) which are vertices of the rectangle. You can find the distance between each point to get the side length and then multiply the two side lengths together.
