Suppose that the x-intercepts of the graph of y = f(x) are 6 and 5. What are the x-intercepts of
9966 [12]

Answer:

The x-intercepts of f(-x) are -6 and -5

Step-by-step explanation:

we know that

The x-intercepts of f(x) are

x=5, x=6

That means

x-5=0

x-6=0

Substitute the variable x by -x

-x-5=0 ----> x=-5

-x-6=0 ----> x=-6

therefore

The x-intercepts of f(-x) are -6 and -5

(-y+5•3)+7.2y-9)=6.2y+n
kramer
(-y+5x3)+(7.2y-9)=6.2y+n
(-y+15)+(7.2y-9)=6.2y+n
since you're adding the two parentheses, you don't need to have them there
-y+15+7.2y-9=6.2y+n
7.2y-y +15-9 =6.2y+n
6.2y + 6 =6.2y+n
6.2y - 6.2y -n = -6
-n=-6
n=6

What is the value of y that satisfies the equation below 5-y/2=9
Andrew [12]
5-y/2 = 9

First, we do the inverse operation and subtract 5 from both sides.
 
  5 - y/2 = 9
-5            -5

-y/2 = 4

Now, we do the inverse operation ( multiply by the reciprocal) 

-y/2 = 4
-y/2 * -2 = 4* -2
y= -8
y=-8

Now we have our final answer: y=-8

Check our work

5 - - 8/2= 9
5+4=9
9=9

OUR ANSWER IS CORRECT! :)
