Answer:

No. Since 7^2 + 9^2 ≠ 11^2, the triangle cannot be a right triangle.

Step-by-step explanation:

You may recall that side lengths of 3, 4, 5 make a right triangle. That particular triple has several interesting characteristics. One is that it is the only (reduced) triple that is an arithmetic sequence (has a constant difference between the side lengths). Any right triangle that has sides that differ by a constant amount must be a multiple of 3, 4, 5.

Here, we have sides of length 7, 9, 11—values that differ by 2. They form an arithmetic sequence that is not a multiple of 3, 4, 5, so we know right away they cannot be sides of a right triangle.

If we want to use the Pythagorean relation to check, we can see if the equation is true:

7² + 9² = 11²

49 + 81 = 121

130 = 121 . . . . . . Not True

Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope

Answers

Answer:

Well I can't do it if you don not show the graph :(

Step-by-step explanation:

Answer:

Let's actually find the line of best fit...

m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)

m=(11*836-130*55)/(11*385-3025)

m=2046/1210

m=93/55

b=(Σy-93Σx/55)/n

b=(55Σy-93Σx)/(55n)

b=(7150-5115)/(55*11)

b=185/55, so the line of best fit is:

y=(93x+185)/55

A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.

Which means that those who do not practice at all will win about 3.36 times

B) y(13)=(93x+185)/55

y(13)≈25.34

So after 13 months of practice one would expect to win about 25.34 times.

Find the value of the x

Answers

Answer:

The answer should be 77, but the triangle in the question seems off. Read the explanation.

Step-by-step explanation:

To find the exterior angle in this problem, you can use the exterior angle theorem.
Interior angle + interior angle = exterior angle
25 + 52 = 77
You can double-check this answer by figuring out the third interior angle.
Since the sum of all the interior angles of a triangle should be 180, you can determine that
25 + 52 + y =180
Y= 103
or, since a straight line is always 180 degrees (Y+X=180)
25+52+(180-x)=180

X= 77
The reason why I think the question looks weird is since 77 is an acute angle, and even though it's the only answer that makes sense in this question, angle X is clearly an obtuse angle, as shown in the picture.

-7y=91
a/9=-4
-1/2m=-9

Answers

1. y= -13
2. a= -36
3. m= -18

Answer:

y = -13

a = -36

m = 18

Step-by-step explanation:

-7y=91

divide both sides by -7

-7y/-7 = 91/-7

y = -13

a/9=-4

multiply both sides by 9

9(a/9) = 9(-4)

a = -36

-1/2m=-9

multiply both sides by 2

2(-1/2m) = 2(-9)

-1m = -18

divide both sides by -1

m = 18
