Given the parent functions f(x) = 5x − 1 and g(x) = 3x − 9, what is g(x) − f(x)?

MissTica

F(x) = 5x − 1

and g(x) = 3x − 9

g(x) - f(x) = (3x − 9) - (5x − 1) ===> -2x-8

Answer:

$x = \boxed{2}\: and\: x = \boxed{ \frac{5}{2} }$

Step-by-step explanation:

$2 {x}^{2} - 9x + 10 = 0 \\ \\ 2 {x}^{2} - 4x - 5x + 10 = 0 \\ \\ 2x(x - 2) - 5(x - 2) = 0 \\ \\ (x - 2)(2x - 5) = 0 \\ \\ x - 2 = 0 \: \: 2x - 5 = 0 \\ \\ x = \boxed{2} \: and \: x = \boxed{ \frac{5}{2} } \\ \\$

Pls help I don’t understand this question very well

kiruha [24]

Answer:

$CD = 12.6866616739cm$

$CD \approx12.7cm$

Step-by-step explanation:

$CB = a$

$AB = b$

$AC = c$

${c}^{2} = {a}^{2} + {b}^{2}$

${a}^{2} = {c}^{2} - {b}^{2}$

$a = \sqrt{ {c}^{2} - {b}^{2} }$

$a = \sqrt{ {12}^{2} - {6}^{2} }$

$a = \sqrt{144 - 36}$

$a = \sqrt{108}$

$CB = \sqrt{108}$

$\sin(D) = \frac{opposite}{hypotenuse}$

$\sin(D) = \frac{CB}{CD}$

$\sin(55) = \frac{ \sqrt{108} }{CD}$

$(CD) \sin(55) = \frac{ \sqrt{108} }{CD} (CD)$

$(CD) \sin(55) = \sqrt{108}$

$\frac{(CD) \sin(55) }{ \sin(55) } = \frac{ \sqrt{108} }{ \sin(55) }$

$CD = \frac{ \sqrt{108} }{ \sin(55) }$

$CD = 12.6866616739cm$

$CD \approx12.7cm$

How to do probibility

Crazy boy [7]

From what I remember, hear is an example cuz idk how to really explain... there are 3 yellow cubes, 4 green, and 2 blue cubes all in one bag. You add the total number of cubes (3+4+2=9) let’s say I want to know what is the probability of grabbing a yellow cube. There is a total of 3 yellow cubes in the bag so just put that over 9 in a fraction (3/9) so that would be your fraction probability and if you want a percentage you just divide the numerator (3) by the denominator (9) which would be .33 so there is a 33% chance of grabbing a yellow cube. I’m so sorry if this didn’t help x-x
