Straight line from -1,11 to 1,3 and then extend the line

\huge\boxed{Hi!}

The slope of the given line is -4, and the y-intercept of this line is 7.

Now, let's graph this line.

First of all, the graph crosses the y-axis at (0, 7)

Plot the point. Now, what does "the slope of the line is -4" mean?

It means we go -4 units up (4 units down) and 1 unit left/right.

"Down 4, over 1, down 4, over 1, down 4, over 1..." Continue until you have a line.

Then, all you should do is take a ruler and connect the points.

Hope it helps! Enjoy your day! :)

Maya walks 9 blocks to school. If she walks 2 blocks in four minutes, how long will it take Maya to get to school.
katrin2010 [14]

Hello!

In order to find this out we should first know the ratio for the time and distance. So it takes her 4 minutes to go 2 blocks. So the ratio looks like this: 4:2. If we are trying to find 9 blocks, then multiply it by 4 and just add the other two minutes .

So in total your answer is: It takes Maya 18 minutes to walk 9 blocks.

I hope it helps!

Work out the volume of the cone, giving your answer
Gwar [14]

Answer:

If the given lengths of 7 cm, 24 cm, and 25 cm for the sides of a triangle satisfy the equation of the Pythagorean Theorem, then, yes, the given side lengths are those of a right triangle. Let's see if they are:

The well-known equation of the famous Pythagorean Theorem is:

a² + b² = c², which says that for a right triangle, the sum of the squares of the lengths of the two shorter sides of the triangle is equal to the square of the length of the longest side called the hypotenuse, where a and b are the lengths of the two shorter sides (also called the "legs") and c is the length of the hypotenuse (the side opposite the right angle).

We're given that a = 7 cm and b = 24 cm and that c = 25 cm. Substituting these values into the equation of the Pythagorean Theorem, we get:

a² + b² = c²

(7 cm)² + (24 cm)² = (25 cm)²

(7 cm)(7 cm) + (24 cm)(24 cm) = (25 cm)(25 cm)

49 cm² + 576 cm² = 625 cm²

625 cm² = 625 cm²

As we can see, the equation of the Pythagorean Theorem is satisfied, i.e., made a true statement, by the given lengths; therefore, if these three lengths, 7 cm, 24 cm, and 25 cm, are the lengths of the sides of a triangle, then the triangle is indeed a right triangle.
