re f(x) = 2x-5 and g(x)= Žx + 5
inverses? Explain.
We are being asked the inverse of the function f(x) = 2x - 5. Now by definition of an inverse function, f(g(x)) = x. f(x) = 2x - 5, so the inverse would be in the following format:
[tex]=> \mathrm{f\left(g\left(x\right)\right)\:=\:2g\left(x\right)\:\:-\:5}\:[/tex]
[tex]=> \mathrm{2g(x) - 5 = x}\:[/tex]
[tex]=> \mathrm{2g(x) = x + 5}\:[/tex]
[tex]=> \mathrm{g(x) = x + 5 / 2}\:[/tex]
I don't understand the inverse function you gave, 'g(x)= Žx + 5' but if it is in other words 'g(x) = x + 5 / 2' then the two functions you gave are inverses.
Solve for X:
-7x -1 = -9x -17
Answer:
-8.
Step-by-step explanation:
-7x - 1 = -9x - 17
-7x - (-9x) = -17 - (-1)
-7x + 9x = -17 + 1
2x = -16
x = -8.

Billy jogs 4/5 kilometers every minute how many kilometers does he jog after 6 1/8 minutes
Answer:
He jogs 4 9/10 kilometers in 6 1/8 minutes
Step-by-step explanation:
If you multiple 4/5 time 6 1/8 you'll get 4.9, which in fraction form is 4 9/10.
how do I find the domain n range of this graph
Domain = {-3, 2}
Range = All real numbers
We can represent the range in interval notation as [tex](-\infty, \infty)[/tex] which is basically saying [tex]-\infty < y < \infty[/tex]. The range is all real numbers due to the arrows meaning the graph extends up and down forever. So any y value is possible.
Notice with the domain we only have 2 valid x values -3 and 2. No other x values are allowed. Normally we use an interval of some kind to set up the domain, but we only have a set of values instead. The curly braces indicate "set".

Yon buys tickets to a concert for himself and a friend. There is a tax of 8% on the price of the tickets and an additional booking fee of $20 for the transaction. Enter an algebraic expression to represent the price per person. Simplify the expression if possible. Use variable t for the price of the 2 tickets in dollars.
Answer:
The answer is 1.06x+10
Step-by-step explanation:
Well, I assume that both tickets cost the same: let's call it x.
So the tickets cost 106%x (the cost of the ticket plus tax).
The total prize of the tickets will be: 2*106% x+20.
But let's assume that you share it half-half then the answer would be 1.06x+10
6. The complement of an angle is 5 less than four times the angle. Find the measure of the angle.
The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
The number of sides of two regular polygons are as 5:4 and the difference between their angles is 9°. Find the number of sides of the polygons,
Answer:
8 and 10.
Step-by-step explanation:
I am assuming the difference of 9° is between their interior angles.
The formula for the interior angle of a regular polygon is 180° - 360°/n, where n is the number of sides.
As the number of sides increase, the interior angle increases.
Therefore 180° - 360°/(5x) = 180° - 360°/(4x) + 9°.
180° - 360°/(5x) = 180° - 360°/(4x) + 9°
360°/(4x) = 360°/(5x) + 9°
90°/x = 72°/x + 9x°/x
=> 90° = 72° + 9x°
9x° = 18°
x = 2.
Hence the number of sides of the regular polygons are 8 and 10.

Convert 150% into a fraction in simplest form
Please do step by step of how you did it PLEASE :)
Answer:
1 1/2 one and a half
Step-by-step explanation:
So we know 100% is 1 whole so we already know we have 1. 50% is half and if we put 1 and 1/2 together is gives us 1 1/2 one and a half hope this answered your question.
Answer:
1.50 is 150% in decimal form and 1 1/2 is in fraction form
Step-by-step explanation:
150 is over 100 so equals 1 whole
50 is left over
50 is half of 100 so 1/2 is the same fraction

Answer:
The Answer is actually B & E if doing this via Connexus. Connexus doesn't view putting an extra zero at the end to be incorrect (as it really isn't, it is just pointless) but Connexus does view NOT selecting that one as incorrect.
So while E is the correct answer, you will only get partial credit if you don't also select B. (With Connexus you can tell ones that are supposed to have multiple answers if they have check boxes instead of radio buttons.)

what is the simplest form of 8√5 + √250 - √720? i’ve been crying over this for an hour pls help
Step-by-step explanation:
8√5 + √250 - √720
= 8√5 + (√2)(√5)(√25) - (√5)(√144)
= 8√5 + 5(√2)(√5) - 12√5
= √5 (8 + 5√2 - 12)
= √5 (5√2 - 4)
= √10 (5 - √2).
