Answer:

-4

Step-by-step explanation:

Original Equation:

1-3n+2n=13+2n

Combine like terms:

1-n=13+2n

Transfer the 1:

-n=12+2n

Transfer 2n:

-3n=12

Divide: (by -3)

n=-4

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:

(-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

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

Answer:

11

Step-by-step explanation:

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]

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:

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
