Step-by-step explanation:
sum of 5 times a number and -2, + 8n
becomes:
5n + (-2) + 8n, or
5n -2 +8n, or. 13n - 2
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
Answer:
d.
Step-by-step explanation:
10^-2 = .01
times 6= .06 and 60%= .6
Given:
The principal = $ 4000
The rate of interest = 22 %
To find the loan amount a) after 1 year and b) after 3 years.
Formula
Loan amount is

where,
A be the loan amount
P be the principal
r be the rate of interest and
t be the time.
Now,
a) Taking, P = 4000, r = 22, t = 1 we get,

or, 
Again,
b) Taking, P = 4000, r = 22 and t = 4 w eget,


Hence,
a) The amount of loan after 1 year is $ 4880
and b) The amount of loan after 4 year is $ 7263.39.
