Answer:

Tim is 48

Step-by-step explanation:

13 x 3 = 39

39 + 9 = 48

If Tim is 3 times the age of John you multiply John's age (13) by 3 and add 9 to the sum because Tim is 9 years older.

Answer:

48

Step-by-step explanation:

3 times 13 (john's age) = 39

39 + 9 = 48 (nine years older than 3 times (39) so you add 9)

Therefore, Tim is 48.

Q(3x)=12x+2 then what is Q(x-2)
Mandarinka [93]

Answer:

it's ax+b form answer is Q(x-2)=4x-6

Step-by-step explanation:

ax+b=Q(x),Q(x-2)=a(x-2)+2

Q(3x)=a(3x)+b=12x+2, 3a=12 =>a=4,b=2

the original q of x is 4x+2

Q of x-2 =4(x-2)+2=4x-8+2=4x-6

Distance between parallel lines y=3x+10 and y=3x-20
Alecsey [184]

1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).


2. Use formula d=\dfrac{|Ax_0+By_0+C|}{\sqrt{A^2+B^2}} to find the distance from point (x_0,y_0) to the line Ax+By+C=0.


The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:

d=\dfrac{|3\cdot 0-10-20|}{\sqrt{3^2+(-1)^2}}=\dfrac{30}{\sqrt{10}}=3\sqrt{10}.


3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.


Answer: d=3\sqrt{10}.

PLEASE HELP, WILL GIVE BRAINLIEST!!!<br><br><br> Find the inverse of f(x)=6x-4<br> and find f^-1(62)
Lena [83]
Answer: 11

=========================

Explanation:

To find the inverse, or f^-1 of a function, you first replace the y= 6x-4 with x=6y-4

Finding the inverse from here is basically just finding y in terms of x.

1) x=6y-4
2) x+4=6
3) (x+4)/6= y

y= (x+4)/6 is now your f^-1.

Now that you have your inverse, replace 62 with your x in y=(x+4)/6

1) (62+4)/6
2) 66/6
3) 11

Therefore, f^-1(62)= 11

Hope this helps :)

The measure of angle 1 is (3x + 10)° and the measure of angle 4 is (4x – 15)°. What is the measure of angle 7
jasenka [17]
Your answer will be 95 degrees. (3x+10)=(4x-15) ends up with x=25. Plug it in to (3x+10). You should get 85 degrees. Using the definition of supplementary angles, angle 3 will be 95. Angle 7 and angle 3 are corresponding angles.
