Answer:
1) 6,000 B) 800 C) 4,000
2)7,500
3)third and fourth one
4)6,951
Step-by-step explanation:
just because
<span>8x-4y = 20
Subtract 8x from both sides
-4y= -8x+20
Divide both sides by -4
Final Answer: y= 2x-5</span>
Answer:
You were supposed to use Desmos Graphing Calculator, not actually do this
Give f<span>(x) = x5 − x4 − 9x3 + 9x2, to obtain the zero we need to factorize the expression. This will give:
x(x+3)(x-1)(x-3)
thus the zeros will be:
x=-3
x=0
x=1
x=3
