Answer:
9• x2
Step-by-step explanation:
Well you have 9 and then you times(•) then X is the number we don’t know. Then x would be squared(like the image below).
Answer:
x=2
Step-by-step explanation:
just add 5 to both sides of the equation
Answer:
P = -30
Step-by-step explanation:
first, you need to move the virable to one side:
3/4P - 4/5P = 3/2
second, you make the denominator the same:
15/20P - 16/20P = 3/2
-1/20P = 3/2
third, you will divide it both side of -1/20:
-1/20 -:- -1/20P = 3/2 -:- -1/20
P = 3/2 x -20/1
P = -60/2
P = -30
Answer:
2x+7/6
Step-by-step explanation:
an normal function would be mapping x to y, since this is the inverse we would map y to x
f(x) and y are the same so I will take f(x) as "y"
1)3x-7/2=y
3y-7/2=x
solve/isolate "y" in 3y-7/2=x to get the value of "y"
3y-7/2=x
add "7/2" to both sides
3y-7/2+7/2=x+7/2
3y=x+7/2
divide both sides by "3"
3y/3=x/3+7/2/3
simplify:
y=2x+7/6
hope this helps!
