Answer:

A negative number

Step-by-step explanation:

I know this is right. Negative numbers represent opposites. If positive represents a movement to the right, negative represents a movement to the left.In the context of negative numbers, a number that is greater than zero is referred to as positive. Thus every real number other than zero is either positive or negative, while zero itself is not considered to have a sign. Positive numbers are sometimes written with a plus sign in front, e.g. +3 denotes a positive three.

Will side lengths of 3 cm, 4 cm, and 5 cm form a triangle? explain.
Gelneren [198K]

Yes, that is the famous first Pythagorean triplet: 3²+4²=5²

or

For three lengths to be able to form a triangle, it suffices that every one of those lengths is shorter than the sum and longer than the difference of the other two.

It is enough to check just one side.

So,

3 + 4 > 5

4 - 3 < 5

Your triangle is constructible.

The answer is going to be 2*sqrt(5). You have to split it into perfect squares for it to be simplified... so in this case, I had sqrt(4*5) because sqrt(4) can be simplified... so your answer would be sqrt(4)*sqrt(5) or 2sqrt(5)

Can I get some help? I will be giving brainliest!

Answer:

1.) slope = 2

2.) slope = -2\frac{2}{3}

3.) slope = \frac{2}{3}

4.) slope = \frac{1}{4}

5.) slope = 1\frac{8}{9}

6.) slope = -2

7.) slope = -3

Step-by-step explanation:

In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.

Now as I said before we know this......

Let "m" be the slope, then....

m = \frac{y}{x}

So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.

1.)

m = \frac{y}{x}

m= \frac{4}{2}

m = 2

2.)

m = \frac{y}{x}

m = \frac{4}{-1.5}

m = -2\frac{2}{3}

3.)

m = \frac{y}{x}

m = \frac{2}{3}

4.)

m = \frac{y}{x}

m = \frac{1}{4}

5.)

m = \frac{y}{x}

m = \frac{8.5}{4.5}

m = 1\frac{8}{9}

6.)

m = \frac{y}{x}

m = \frac{2}{-1}

m= -2

7.)

m = \frac{y}{x}

m = \frac{3}{-1}

m = -3
