Written in 2-point form, the equation of the line is
y = (y2-y1)/(x2-x1)·(x-x1) +y1
y = (3-(-5))/(-6-(-4))·(x-(-4)) + (-5)
y = 8/-2·(x +4) - 5
y = -4x -21
The value of b is -21.
Answer:
(5x²+2y² + 2xy)(5x²+2y²-2xy)
Step-by-step explanation:
25x⁴+4x²y²+4y⁴= (5x²)²+2*5x²*2y²+(2y²)² - 16x²y²= (5x²+2y²)² - (4xy)²= (5x²+2y² + 2xy)(5x²+2y² - 2xy)
Answer:
y = 1/20 x + 5
Step-by-step explanation:
Let the height of the sand dune after x years be represented by the equation
y = mx+c where;
m is the rate at which the hills is eroding
c is the height of the dunes above the sea
If The hill is eroding at a rate of 1 foot per 20 years,then the rate of eroding per year will be;
1foot = 20years
m = 1year
Cross multiply
20m = 1
m = 1/20 foot/yr...
c = 5foot
Substitute into the formula:
y = 1/20 x + 5
Hence the equation that represent the situation is y = 1/20 x + 5
Are you asking what the price would be if it decreases? You must be more clear than that please- if that is the case then what I like to do to solve these is to divide the 175 by 100 because that's kind of what it relates to a percent... and then I multiply by 96. So in this problem:175/100= 1.751.75 x 94 and then that equals your answer 164.50 euros is the new cost of the ticket.Hope this Helps!P.S a thanks or brainliest would mean a lot. :)
Answer:
15% of interest paid on this loan.
Step-by-step explanation:
We are given that Johnny Rockefeller had a bad credit rating and went to a local cash center.
Loan amount of Johnny Rockefeller = $100
He paid the amount in in two weeks = $115
Amount of interest = $115-$100=$15
Let x% be the rate of interest.
So, 
x = 15
Hence 15% of interest paid on this loan.
