The first equation, 8x - 9y = - 23
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = ( 
, 3) and (x₂, y₂ ) = (- 4, - 1 )
m = 
= (- 4)/- 
= 
partial equation is y = x + c
to find c substitute either of the 2 points into the partial equation
using (- 4, - 1 ), then
- 1 = - 
+ c ⇒ c = 
y = x + ← in slope- intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearrange the slope- intercept equation into this form
multiply through by 9
9y = 8x + 23 ( subtract 9y and 23 from both sides )
8x - 9y = - 23 in standard form
Set up the equation 3x+1= 4x-7 and you’ll get your answer
I would go with 115 is the answer you
Answer:
the rate of inflation is 2%.
Step-by-step explanation:
given:
Nominal interest rate =3%
Real interest rate=1%
To Find:
Rate of inflation=?
Solution:
Nominal interest rate:
Nominal interest rate refers to the interest rate before taking inflation into account.
Inflation rate:
The inflation rate is the percent increase or decrease in prices during a specified period. It's usually over a month or a year.
Real interest rate:
A real interest rate is an interest rate that has been adjusted to remove the effects of inflation to reflect the real cost of funds to the borrower and the real yield to the lender or to an investor.
Real interest rate ≈ nominal interest rate − inflation rate.
This can be re written as
inflation rate= Real interest rate - nominal interest rate
Substituting the values,
inflation interest = 1+3
inflation interest=4%
i hope this helpsss<3
:)
if u didnt undersstand make sure to tell me so i can try to say it again
