Does 4.5, 6, and 7.5 make a right triangle?

Answer:

They intercept at (-4.5, -11.5)

Step-by-step explanation:

Answer:

I don't know exactly, I think it is EO, but I could be wrong.

Step-by-step explanation:

The side with intermediate length is OE .

Relationship of sides to interior angles in a triangle

In any triangle:

According to the question

Side opposite to smallest ∠20° = OD

Side opposite to largest ∠110° = DE

Side opposite to intermediate ∠50° = OE

Now,

according to the relationship between length of side of triangle and their interior angle

The smallest side is opposite the smallest angle, and the longest is opposite the largest angle, then it follows that since a triangle only has three sides, the midsize side is opposite the midsize angle.

Therefore,

OD = smallest side

DE = Largest side

OE = intermediate side

Hence, The side with intermediate length is OE .

Step-by-step explanation:

Answer:

So the slope is -2 while the y-intercept is -2

Step-by-step explanation:

y=mx+b

so you need to rearrange it so it will be

y=-2x-2

So m is slope so it is -2

and -2 is b which is the y-intercept so it is -2

Answer:

17

Step-by-step explanation:

if you subtract 4 from 89, which is the shipping cost. 89 - 4 = 85. Then divided 85 by 5 because that will show how much he paid for them in total, by how much a singular book is. Telling you how many books he bought. 85/5 = 17.

Answer:

A.) 5b+4=89

B.) 17 books

Step-by-step explanation:

To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89",  because it says that is the total cost. So we get the equation 5b+$4=$89

To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get 5b=$85. Now we divide by 5 to get only the variable and to get rid of the coefficient. We get b=17. So Sam bought 17 books.

A perfect square means that all side are EXACTLY equal. I hope this helps!

Step-by-step explanation:

In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number

Answer:

y = -2x + 1

Step-by-step explanation:

The y-intercept is given by the point that is on the y-axis. (1)

This means that the answer contains a +1

Then you must find  if the slope is positive or negative

In this case the slope is negative because the line goes "downhill" from left to right

Since the slope is negative it means that there will be a negative sign in the beginning of the equation

Next, to find the slope you need to find the rise over run

Since it is a negative slope the rise will be negative and the run will be positive.

To find the slope find two clear points on the graph such as (0,1) and (2,0)

To find the slope, use the slope formula

This would look like: (0-2)/(1-0)

Your slope will be -2x

Piece it all together and you get a final answer of y= -2x+1
