Answer:
28x + 8y + 2
Step-by-step explanation:
Combine like-terms within the parentheses, then distribute -2.
Hope this helps! :)
Given that the decay rate of the uranium is given to be 57%, this means that on the second day only 43% of the Uranium-233 will be left. The equation therefore, that will allow us to answer the question is that,
A(t) = A(0)(1 - r)^n
where A(t) is the amount after n days, A(0) is the original amount, r is the decimal equivalent of the rate and n is the number of days. Substituting the known values,
A(t) = (3,820 pounds)*(1-0.57)^15
A(t) = 0.0121 pounds
This is unfortunately not found in the choices.
Well, you can actually tell it is D without solving it because it is the only one that has the x value as 3. But just to be sure.
Plug in 3 for x into the equation:
3(3)-y=9 and solve for y
9-y=9 subtract 9 from both sides
-y=0 so y=0
so the value is (3,0)
57-34x5-45-67x78x98 equals fifty nine
Answer:
<u>4.1 </u>
Step-by-step explanation:
0.4(-5)+6.1
0.4 times -5 is -2
-2 +6.1 = <u>4.1 </u>
