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
Answer:21/7
Step-by-step explanation:
(-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
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! :)
Answer:
The mean is: 19
Step-by-step explanation:
Add all of those numbers up (133)
Divide it by the total amount of numbers (7)
133÷7=19
