Sam gets (500/10)*3=150<span>£
harry gets (150/100)*35= 52.5</span>£
x = -29
because
0.35x +1.4=0.25x-1.5
-0.25x -0.25x
_____________________
0.1x + 1.4 = -1.5
-1.4 -1.4
_________________________
0.1x =-2.9
____ _____
0.1 0.1
x = -29
Answer:
False
Step-by-step explanation:
f(x) = 4x³ - 12x² - x + 15
Set output to 0.
Factor the function.
0 = (x + 1)(2x - 3)(2x - 5)
Set factors equal to 0.
x + 1 = 0
x = -1
2x - 3 = 0
2x = 3
x = 3/2
2x - 5 = 0
2x = 5
x = 5/2
-2 is not a lower bound for the zeros of the function.
