Answer:
4x^2-13x+4
Step-by-step explanation:
1. Add together all like terms ( so x^2+3x^2=4x^2)
2. once you add all your like terms. order the numbers from biggest to smallest (4x^2'-13x+4)
*You'll know which is biggest by the exponent!
Hope this helps!!!!!
Answer: In 10 hours, 4000 bacteria will be present.
Step-by-step explanation:
Given that 2000 bacteria grew to 2400 in 2 hours,
growth/ increase rate = 2400 - 2000
= 400 bacteria increase in 2 hours
Per hour is therefore 400/2 = 200 bacteria increase per hour
If the bacteria increases by 200 per hour
If 200 = 1 hour
X = 10 hours
We cross multiply:
X = 200 x 10
X = 2000
Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours
So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria
Answer: y= -2x
Step-by-step explanation:
(-3,6)(3,-6)
M= -6-6/3-(-3)
M= -12/6
M= -2
(-3,6 ) and m= -2, find b
Y=mx+b
6=-2(-3)+b
6= 6+b
6-6=b
0=b
Y= -2x
