Answer:
5%
Step-by-step explanation:
The question showing a growing function that commonly used in compound interest calculation. The formula for compound interest is:
A = P (1 +r) ^ t
A= amount of the balance after a period of t
P= principal, the initial money deposit
r= rate
t= time
The percent of balance increase should be represented by the rate(r). In this equation, the principal will be 130, (1+r) will be 1.05, and time will be x.
The value of rate (r) will be:
(1+r) = 1.05
r= 1.05-1= 0.05 = 5%
Answer:
m=-30
Step-by-step explanation:
2m+10=5m+100
get rid of 2m by subtracting
10=3m+100
get rid of 100 by subtracting
-90=3m
divide by 3
-30=m
m=-30
$50+$10 (The coupon)=$60 to spend
$60/12=5 uniform shirts.
80 Pounds, If its above 5, round up, below round down.
Y = 1/2x + 6
slope here is 1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/2
(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 1/2(0) + b
-2 = b
so ur parallel equation is : y = 1/2x - 2
