Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5
z = 2
'Answer:
Step-by-step explanation:
z + 22
---------- = 12
z
Multiplying both sides by z results in
z + 22 = 12z
Combining the z terms, we get 22 = 11z, which yields z = 2.
Answer: 399/640
What is those three dots tho???
Answer:
Concept: Mathematical Analysis
- They go in opposite directions
- They start at the same point, let's define that as (0,0) on the ordinary differntiable x-y axis
- Hence Tom can ride 20 units left in one hour and Juanita can ride 20 units right in one hour.
- We want to know the distance they are at the end of 2 hours
- So we set up the equation y= 20(x)
- Let x be the hours and y be the distance
- So 20×2=40 miles
- At the end of 2 hours they will be 40 miles apart assuming constant rate of change and a starting point of (0,0)
