Your answer is 4/5 because is see you put 8/10 which is correct but all you needed to do is simplify.
Answer:
d = 7.2
Step-by-step explanation:
To get d by itself, multiply both sides by 1.2.
d = 7.2
Answer:
x=1
Step-by-step explanation:
According to your typed question,
f(x)=2x-3
Let f(x)=y
y=2x-3
Now,
Interchanging the positions of x and y
x=2y-3
x+3=2y
x+3/2=y
f'(x)=x+3/2
Then,
f(x)=f'(x)
2x-3=x+3/2
2(2x-3)=x+3
4x-3=x+3
4x-x=3+3
3x=3
x=3/3
x=1
According to your image question,
f(x)=x/2x-3
f(x)=f'(x)
Now,
Let y=f(x)
y=x/2x-3
y(2x-3)=x
2xy-3=x
2xy-x=3
x(2y-1)=3
2y-1=3x
2y=3x+1
y=3x+1/2
f'(x)=3x+1/2
Then,
f(x)=f'(x)
x/2x-3=3x+1/2
2x=6xsq+2x-9x+3
2x=6xsq+7x+3
solve for x ok
Answer:
21 + 4 = 25
Step-by-step explanation:
this is the answer because the temperature fell 4 degrees in the last hour.
so we have to add back that 4 to get the answer.
our equation will be 21 + 4 equals 25.
hope this helps!
