Answer:

(-15,7) (11,7) (-2,20) (-2,-6)

Step-by-step explanation:

There are four possible coordinate pairs which are (-15,7), (11,7), (-2,20) and (-2,-6).

Given that Point M is located at (-2,7).

If point N is 13 units away from point M,  we have to find the possible cordinate pairs.

When N is vertically upwards of M, then the x point will not change but the point y is increased by 13.

So the point N is located at (-2, 7+13) which is (-2, 20).

When N is vertically downwards of M, then the x point will not change but the point y is decreased by 13.

So the point N is located at (-2, 7-13) which is (-2, -6).

When N is horizonatally rightside of M, then the y point will not change but the point x is increased by 13.

So the point N is located at (-2+13, 7) which is (11, 7).

When N is horizonatally leftside of M, then the y point will not change but the point x is decreased by 13.

So the point N is located at (-2-13, 7) which is (-15, 7).

Hence, there are four possible coordinate pairs which are (-15,7), (11,7), (-2,20) and (-2,-6).

For 26

a) We could first rotate clockwise 90 degrees from the origin, and then reflect on the x axis.

b) We could rotate counterclockwise 90 degrees and then reflect on the y axis.

For 27

a) Rotate counterclockwise 90 degrees from the origin, then translate down 1

b) Reflect on x axis, rotate 90 degrees clockwise, then reflect on x axis, translate down 1, left 1

These are just a couple of the possible ways to solve this, try to figure out some more for yourself!

Answer:

n = 10

Step-by-step explanation:

Using the rule of exponents

• [tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

• [tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

Then

2² × [tex]2^{n}[/tex] = [tex](2^4)^{3}[/tex]

[tex]2^{2+n}[/tex] = [tex]2^{12}[/tex]

Since the bases on both sides are equal, both 2 then equate exponents

2 + n = 12 ( subtract 2 from both sides )

n = 10

Answer:

Disciminant of f = 0

x-intecept = [tex](\frac{3}{2}, 0)[/tex]

Step-by-step explanation:

Given the quadratic function, -4x² + 12x - 9

where a = -4, b = 12, and c = -9

The discriminant, b²- 4ac, is the expression inside the radical (numerator) of the quadratic formula:

[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]

The first part of your given problem asks for the discriminant. Substitute the values for a, b, and c:

b²- 4ac = 12² - 4(-4)(-9) = 144 - 144 = 0  → This implies that the quadratic function has one real root.

Therefore, the disciminant of f is 0.

Next, the given problem asks for the x-intercepts. The x-intercept is the point on the graph where it crosses the x-axis. As I mentioned earlier, the function has one real root. Therefore, it means that there is only 1 x-intercept.  To find out what the x-intercept is, use the quadratic formula:

[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]

[tex]x = \frac{-12 +/- \sqrt{12^{2}-4(-4)(-9)} }{2(-4)}[/tex]

[tex]x = \frac{-12 +/- \sqrt{144 - 144} }{-8}[/tex]

[tex]x = \frac{-12}{-8} = \frac{3}{2}[/tex]

Therefore, the x-intercept is [tex](\frac{3}{2}, 0)[/tex].  

Answer:

65

Step-by-step explanation:

Answer:

A. - 6

Is the common difference

see the expressions below that prove so.

Step-by-step explanation:

The sequence shows -6 to each number is same as k-6 or even n-6

we use such letters to represent 1 value. Also the reason it is a negative number is because the numbers are decreasing within the sequence.

The nth expression is the first term equation shows -6n

and the number prior to 45 is  45+6 = 51

Put together this creates our nth term =   -6n + 51

The next term is where we use the common difference also.

next nth term =  (27) + (- 6) = 21   and so on proves it the 5th term

5th nth term = -6 x 5 +51 = 21

100th nth term = -6 x 100 +51 = -549

Step-by-step explanation: Because, you're rounding to the nearst tenth and .36 has a 6 in it anything above a 5 you round up and anything under you round down.

There are 15 possible triples of three positive integers whose product is 16.

According to this question, we must find the quantity of all possible triples such that they have a product of 16. By factor decomposition, we have that 16 is equal to the following product of prime numbers:

[tex]16 = 2^{4}[/tex]

There are the following triples considering order of factors:

(i) [tex]\{16, 1, 1\}[/tex], (ii) [tex]\{1, 16, 1\}[/tex], (iii) [tex]\{1, 1, 16\}[/tex], (iv) [tex]\{2, 8, 1\}[/tex], (v) [tex]\{8, 2, 1\}[/tex], (vi) [tex]\{8, 1, 2\}[/tex], (vii) [tex]\{2, 1, 8\}[/tex], (viii) [tex]\{1, 2, 8\}[/tex], (ix) [tex]\{1, 8, 2\}[/tex], (x) [tex]\{1,4,4\}[/tex], (xi) [tex]\{4, 1, 4\}[/tex], (xii) [tex]\{4,4,1\}[/tex], (xiii) [tex]\{2,2,4\}[/tex], (xiv) [tex]\{2, 4, 2\}[/tex], (xv) [tex]\{4,2,2\}[/tex]

There are 15 possible triples of three positive integers whose product is 16.

Answer:

x = 15

Step-by-step explanation:

<JKM is the sum of the two smaller angles.

<JKL + <LKM = <JKM

<JKM = 154

<JKL  = 6x

<LKM = 3x + 19

6x + 3x + 19 = 154             Subtract 19 from both sides

9x + 19 - 19 = 154-19         Combine            

9x = 135                            Divide by 9

9x/9 = 135/9

x = 15
