Type the expression that results from the following series of steps: Start with
t
subtract
r
, multiply by
x
, then add
p
.

Step-by-step explanation:Given the variable n

we have to write the expression of variable n adding with 5 then multiply the product by 4 then subtract 7 from the result

add variable n with 5 is (n+5)

multiply the result by 4 is (n+5)

subtract 7 from the result is ((n+5))-7

So the expression is ((n+5))-7

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

a)(x-2)^2+(y-1)^2=9
