To simplify x^2-3 =5x
You would first subtract 5x from both sides
X^3-5x-3
Next you would plug this into the quadratic equation:
X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)
Then simplify,
5+/- the squareroot of 24 + 12 / 2
5+/- The squareroot of 36 /2
5+/- 6 / 2
Then solve if it’s an addition or subtract
5+6/2
X=11/2 or 5 1/2
5-6/2
X= -1/2
The answer is x=-1/2 or x=11/2
Hope this helps

Answer:
Option D. h(2) = 16
Step-by-step explanation:
Verify each statement
case A) h(8) = 21
The statement is false
Because
we know that
h(8)=19 -----> given value
and
If h(8) = 21 then f(x) is not a function
case B) h(13) = 18
The statement is false
Because x=13 not belong to the domain of the function
case C) h(-3) = -1
The statement is false
Because
x=-3 belong to the domain
but
h(-3)=-1 not belong to the range of the function
case D) h(2) = 16
The statement could be true
Because
x=2 ----> belong to the domain of the function
h(2)=16 ----> belong to the range of the function
Answer:
45 mph
Step-by-step explanation:
Given: Distance travelled= 330 miles
Time taken= 6 h
Lets find out speed of car drove.
Formula; 
Speed= 
∴ Car´s speed is 55 mph.
As we have been informed that car´s rate of travel slows by 10 mph
∴ we have to reduce the current speed of car by 10 mph; 
The new slower rate of travel is 45 mph.
