Answer:
Yes
Step-by-step explanation:
3.5 [4d - 2*1.5] = 3.5*4d - 3.5*2*1.5
= 14d - 10.5
2*[7d - 5*1.05] = 2*7d - 2*5*1.05
= 14d - 10.5
When we are simplifying both the expression using distributive property, we get the same expression at the end.
Answer:
x = -1 or x = -7
Step-by-step explanation:
y = (x + 4)^2 - 9
To find x-intercept, set y = 0
=> (x + 4)^2 - 9 = 0
=> ( x + 1)( x + 7) = 0
=> x = -1 or x = -7
Answer:
There will be 200 000 bacteria after 8 hours
Step-by-step explanation:
The crop quadruples every hour.
x represents the number of hours that pass after preparing the crop
y represents the number of bacteria after x hours.
The equation for y in function of x 3 hours after observing the crop is:

We want to know after how long there will be 200 000 bacteria.
Then we make y = 200 000 and clear x.
