Answer:
To find the equation of the line parallel to the graph, first of all find the slope of the graph by making y the subject of the formula and comparing the resulting equation with y = mx + c , knowing fully well that m stands for the slope.
So, from the equation of the graph give, y = 4x/5 +1/5, therefore the slope is 4/5. For a line to be parallel to the graph then they must have the same slope, to find the equation of the line at the given point, then we use the formula
y - y1 = m ( x - x1 )
y - 3 = 4/5 ( x - 1 )
multiply through by 5
5( y - 3 ) = 4 ( x - 1)
5y - 15 = 4x - 4
5y - 4x = - 4 + 15
so, 5y - 4x = 11 is the equation

Step-by-step explanation:
15.25 for blueberry pie = 24 slices (8 slices in a pie)
12.84 for cherry pie = 15 slices (8 slices in a pie)
24x3.50=84
15x3.50=52.5
2x12.84=25.68
3x15.25=45.75
84-45.75=34.25
52.5-25.68=26.82
Answer:
2, 9, 2, 9
Step-by-step explanation:
length = x
width = y
xy = 18
2x + 2y = 22
Substitute the second equation into the first. to do that, rewrite the equation
2x + 2y = 22 becomes y = -x + 11
Then use the new equation and substitute it with the y in the first equation.
x(-x + 11) = 18
-x^2 +11x - 18
Divide by -1
x^2 -11x + 18 = (x - 2) (x - 9)
x = 2, 9
when x = 2, y = 9 and when x = 9, y = 2 so they are interchangeable. the sides are 2, 9, 2, and 9.
Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%
