Answer:
See answer and graph below
Step-by-step explanation:
∬Ry2x2+y2dA
=∫Ry.2x.2+y.2dA
=A(2y+4Ryx)+c
=∫Ry.2x.2+y.2dA
Integral of a constant ∫pdx=px
=(2x+2.2Ryx)A
=A(2y+4Ryx)
=A(2y+4Ryx)+c
The graph of y=A(2y+4Ryx)+c assuming A=1 and c=2
Answer:
A.
x + y = 28
1.68x + 2.44y = 54.64
Step-by-step explanation:
Let x = paperback books and y = hardback books
x+y =28
We know that paperbacks cost 1.68 and hardback cost 2.44
1.68x + 2.44y = 54.64
We have 2 equations and 2 unknowns
x+y =28
1.68x + 2.44y = 54.64
2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
I assume you're looking for the value of x?
Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180
Add 5 to both sides: 15x=185
Divide both sides by 15: x=12 1/3
So x is 12 1/3 or 37/3

Answer:
y=
x
Step-by-step explanation:
Given the two points:
- Origin (x1, y1) = (0, 0)
- The point (x2, y2) = (5, 9)
Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).
=>Time, x the independent variable,and distance is the dependent variable.
We have the standard form of a linear equation is:
y= mx + b where a is the slope
We know that, the slope of the function is:
m =
In this situatuon, m =
=> y=
x + b(1)
The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:
0 =
*0 + b
<=> b = 0
So our equation that the graph represents is: y=
x
