Answer:

B. Twenty-three dollars is the price for each ticket

Step-by-step explanation:

The answer is B because 1 concert ticker is $23. If you buy 2 concert tickets, the price would go up by x2 $46. You are basically buying $23 for 1 concert ticket and $23 for each 1 concert ticket you buy. Hope this helps

Answer:

A. [tex] y = \frac{1}{4}x + 2 [/tex].

Step-by-step explanation:

Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].

Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].

Thus, the equation of the line would be:

[tex] y = \frac{1}{4}x + 2 [/tex].

Answer:

[tex]\theta = 108.29[/tex]

Step-by-step explanation:

Given

[tex]u = <2,6>[/tex]

[tex]v = <4,-7>[/tex]

Required:

Calculate the angle between u and v

The angle [tex]\theta[/tex] is calculated as thus:

[tex]cos\theta = \frac{u.v}{|u|.|v|}[/tex]

For a vector

[tex]A = <a,b>[/tex]

[tex]A = a * b[/tex]

[tex]cos\theta = \frac{u.v}{|u|.|v|}[/tex] becomes

[tex]cos\theta = \frac{<2,6>.<4,-7>}{|u|.|v|}[/tex]

[tex]cos\theta = \frac{2*6+4*-7}{|u|.|v|}[/tex]

[tex]cos\theta = \frac{12-28}{|u|.|v|}[/tex]

[tex]cos\theta = \frac{-16}{|u|.|v|}[/tex]

For a vector

[tex]A = <a,b>[/tex]

[tex]|A| = \sqrt{a^2 + b^2}[/tex]

So;

[tex]|u| = \sqrt{2^2 + 6^2}[/tex]

[tex]|u| = \sqrt{4 + 36}[/tex]

[tex]|u| = \sqrt{40}[/tex]

[tex]|v| = \sqrt{4^2+(-7)^2}[/tex]

[tex]|v| = \sqrt{16+49}[/tex]

[tex]|v| = \sqrt{65}[/tex]

So:

[tex]cos\theta = \frac{-16}{|u|.|v|}[/tex]

[tex]cos\theta = \frac{-16}{\sqrt{40}*\sqrt{65}}[/tex]

[tex]cos\theta = \frac{-16}{\sqrt{2600}}[/tex]

[tex]cos\theta = \frac{-16}{\sqrt{100*26}}[/tex]

[tex]cos\theta = \frac{-16}{10\sqrt{26}}[/tex]

[tex]cos\theta = \frac{-8}{5\sqrt{26}}[/tex]

Take arccos of both sides

[tex]\theta = cos^{-1}(\frac{-8}{5\sqrt{26}})[/tex]

[tex]\theta = cos^{-1}(\frac{-8}{5 * 5.0990})[/tex]

[tex]\theta = cos^{-1}(\frac{-8}{25.495})[/tex]

[tex]\theta = cos^{-1}(-0.31378701706)[/tex]

[tex]\theta = 108.288386087[/tex]

[tex]\theta = 108.29[/tex] (approximated)

Answer:

27.73

Step-by-step explanation:

You do 3.25 x 7.3= 23.725 so you round the 2 up to a 3. So then you do

23.73+ 4.00= 27.73

Answer:

x² - 25

Step-by-step explanation:

Given:

(x-5)(x+5)

Find:

Product

Computation:

(x-5)(x+5)

(a+b)(a-b) = a² - b²

(x-5)(x+5) = x² - 5²

(x-5)(x+5) = x² - 25

Alternate:

(x-5)(x+5)

x² + 5x - 5x - 25

x² - 25

Answer:

x'1 = -1

x'2 = 8

Step-by-step explanation:

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

x² - 7x - 8 = 0 ( add 8 to both sides )

x² - 7x = 8

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- [tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] = 8 + [tex]\frac{49}{4}[/tex] = [tex]\frac{81}{4}[/tex]

(x - [tex]\frac{7}{2}[/tex] )² = [tex]\frac{81}{4}[/tex] ( take the square root of both sides )

x - [tex]\frac{7}{2}[/tex] = ± [tex]\sqrt{\frac{81}{4} }[/tex] = ± [tex]\frac{9}{2}[/tex] ( add [tex]\frac{7}{2}[/tex] to both sides )

x = [tex]\frac{7}{2}[/tex] ± [tex]\frac{9}{2}[/tex]

Thus

x = [tex]\frac{7}{2}[/tex] - [tex]\frac{9}{2}[/tex] =  [tex]\frac{-2}{2}[/tex] = - 1

x = [tex]\frac{7}{2}[/tex] + [tex]\frac{9}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8

Answer:

4 - i

Step-by-step explanation:

Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i.  Also, we know that  i will not be in the end result, which means that we should have a negative in the result as well.

To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:

[tex]d = \sqrt{4^2 + (-i)^2} \\d = \sqrt{16 + 1}\\d = \sqrt{17}[/tex]

So indeed the answer is 4 - i
