Y+x=98
y-x=22

I'm going to use elimination. 

y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60. 

Substitute that into either equation and you get y=60 and x=38

Have a nice day! :)

Question 8 of 10 (1 point)
LUCKY_DIMON [66]
3(n-8)=2n-2

3n-24=2n-2

Subtract 2n from both sides to get

n-24=-2

Adding 24 to both sides gives you

n=22. The number therefore is 22. Hope this helps!!!

Given the functions m(x) = 4x − 11 and n(x) = x − 10, solve m[n(x)] and select the correct answer below. (2 points)
Citrus2011 [14]
For this case what we must do is a composition of functions which will be given by:
 m (x) = 4x - 11
 n (x) = x - 10
 We have then:
 m [n (x)] = 4 (x - 10) - 11
 Rewriting the function:
 m [n (x)] = 4x - 40 - 11
 m [n (x)] = 4x - 51
 Answer:
 a. m [n (x)] = 4x - 51

PLEASE HELP WITH ALGEBRA QUESTION NEED ASAP!!
Delvig [45]

Answer:

The function f(x) = ln(x - 4) is graphed the question options

Step-by-step explanation:

* Lets study the the information of the problem

- The graph of a logarithmic has a vertical asymptote at x=4

* That means the curve gets closer and closer to the vertical line x = 4

  but does not cross it

- It contains the point (e+4, 1)

* That means if we substitute x = e + 4 in the equation the value

 of y will be equal to 1

- It has an x-intercept of 5

* That means if we substitute y = 0 in the equation the value of x

  will be equal to 5

* Lets find the right answer

∵ f(x) = ln(x - 4)

* To find the equation of the asymptote let x - 4 = 0

∵ x - 4 = 0

∴ x = 4

∴ f(x) has a vertical asymptote at x = 4

* Lets check the point (e + 4 , 1) lies on the graph of the f(x)

∵ x = e + 4

∴ f(e+4) = ln(e + 4 - 4) = ln(e)

∵ ln(e) = 1

∴ The point (e+4 , 1) lies on the graph of the function f(x)

* To find the x-intercept put y = 0

∵ f(x) = 0

∴ ln(x - 4) = 0

* Change the logarithmic function to the exponential function

- The base of the ln is e

∴ e^0 = x - 4

∵ e^0 = 1

∴ x - 4 = 1 ⇒ add 4 to the both sides

∴ x = 5

* The function f(x) = ln(x - 4) is graphed the question options
