Answer:
The slope of the line given by the equation -3x=30-5y is 
.
Step-by-step explanation:
-3x=30-5y
Move the -3x to the right side of the equal sign and the -5y to the left.
5y=30+3x
By switching them to opposite sides, their sign changes from - to +.
Then, divide both sides by 5 in order to isolate the y.
You get:
<em>y= </em>
<em />
According to y=mx+b, mx refers to the slope.
In this case, the slope would be .
Answer:
Written Below.
Step-by-step explanation:
A system of linear equations has one solution when the graphs intersect at a point. A system of linear equations has no solution when the graphs are parallel. A system of linear equations has infinite solutions when the graphs are the exact same line.
(This uses graphing.)

Answer:
nominal rate of interest is 31.7 %
Step-by-step explanation:
given data
payment = $1000
time = 2 year
rate = 4%
CPI = 100
CPI final yer = 127.7
to find out
nominal rate of interest
solution
we know nominal rate of interest formula that is
nominal rate of interest = real interest rate + inflation rate .........1
so here inflation rate is express as
inflation rate = ( CPI final year - CPI ) / CPI × 100 ...........2
put here value
inflation rate = ( 127.7 - 100 ) / 100 × 100
inflation rate is 27.7 %
so from equation 1
nominal rate of interest = real interest rate + inflation rate
nominal rate of interest = 4% + 27.7%
nominal rate of interest is 31.7 %
