Answer:
(x-3) (x+5) => x*x+5x-3x-15
=> x*x+2x-15
Step-by-step explanation:
Answer:
the first cell next to 3 (time hours x) is 300
the point is (3, 300)
the second cell is 1000
the point is (10,1000)
the values for the second table should be the same if they have the same unit rate which is 100 watts per hour
Step-by-step explanation:
If there is 100 watts perhour just multiply the number of hours by this unit
Answer:
you graph it on the LINE and find the slope
Answer: x>-4/3
Step-by-step explanation:All sides must be greater of zero:
3x+4>0
3x> -4 Divide with 3
x> -4/3
6x-1>0
6x>1 Divide with 6
x>1/6
8x+2>0
8x> -2 Divide with 8
x> -2/8
x> -1/4
Least of that numbers is -4/3= -1.3333
x> -4/3 is solution
It would be -4. subtracting a positive is the same as adding a negative
