Answer:
25 ÷ 5 + 7 - (4 × 3)
First Brackets :
4 x 3
= 12
Now division :
25 ÷ 5
= 5
So now this is our equation :
<em>5</em><em> </em><em>+</em><em> </em><em>7</em><em> </em><em>-12</em><em> </em>
<em>Work</em><em> </em><em>From</em><em> </em><em>left</em><em> </em><em>to</em><em> </em><em>right</em><em>:</em>
5 + 7
= 12
12 - 12
==> 0
Hope it helps :))
hey the answer is the last one z= 2k -5
Answer:
p=6
Step-by-step explanation:
First use the Distributive property to distribute the -3 to both (3p) and (6):
-84=-9p-18-2p
Now combine alike terms! (-9p-2p):
-84=-11p-18
Now add 18 to both sides!
-66=-11p
Now divide both sides by -11!
6=p
This can be rearranged to give you a final answer of p=6
Yes it’s a straight line wh no curves
Answer:
<em>B. f(n) = 56(0.5)^n-1</em>
Step-by-step explanation:
First, You have to find out the starting population, if you look at the problem you see the population starts at 56
f(x) = 56
Second, you know that the population goes down 50% each week so it has a decay of 0.5
f(x) = 56(0.5)
Third, you need to add the exponent of n to make it exponential. But, if you just add n then the the population would be 28 on week 1 which is incorrect. To fix that you make the exponent n-1 so when you are on week 1 it doesn't become 28 but it stays on 56, and on week 2 it's 28, ect
f(x) = 56(0.5)^n-1
