Now, to find 'x' you will apply the Null Factor Law. This means you will now let 'x' = 0, and simply move the -2 over to the other side to find your answer. Note: since we are using a perfect square, x will only have one value since there is only one answer (x-2) in the brackets, meaning in this case we can ignore the exponent (as the answers will be the same). If there was more than one answer in the bracket (e.g. (x-4) and (x-6)), then we would apply Null Factor Law to both brackets and solve for x.
(x−2)=5
x=5+2
x=7
Answer:
The average velocity is 19.44 m/s.
Step-by-step explanation:
The average velocity between two points can be calculated with the following formula:
The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.
Answer:
Below.
Step-by-step explanation:
[(x - 3)(x +3)] / [(x - 3)(x - 10)]
The x-3 cancels out.
Answer:
-86
Step-by-step explanation:
simplify each equation as much as possible
f(x)= 4x(2+9) add
4x(11) multiply
f(x)=44x
substitute given numbers into each equation
44(-2)=-88 3(4)-14= 12-14=-2
combine equations
-88-(-2)= -86 add since you are subtracting a negative number
