we have that
y = 3x - 2
10(x+3/5)=2y------> the second equation----->divide by 2 both sides
5(x+3/5)=y-----> y=5x+3
y=5x+3------> second equation written in slope-intercept form
so
case A) y=5x+3/10-----> is not equal to y=5x+3
case B) y=5x+3--->is equal to y=5x+3---------> is the answer
case C) y=1/5x+3/25-------> is not equal to y=5x+3
case D) y=1/2x+6-----> is not equal to y=5x+3
therefore
the answer is the option
B) y=5x+3
The answer is A. You have to isolate the variable(f) by subtracting 0.2 from both side. When youve done that, the answer should be -3.2

Step-by-step explanation:
➨ We can also solve by completing both squares, however. Since we can pull out the square root.
➩ Define of Absolute Value/Square Root
➩ 
Thus, our new equation is ➩ 
To solve an absolute-value equation, let there be two conditions.
➨ Where x ≥ 0
Move x to another side
➨ Where x < 0
If the slope of AB = CD and BC = AD it's a parallelogram:
Slope of AB = 6+1 / -9+5 = -7/4
CD = -2-5 / 3+1 = -74
These are equal.
BC = 5-6 / -1 +9 = -1/8
AD = -2 +1 / 3+5 = -1/8
These are also equal so it is a parallelogram.
Now to find if the diagonals are perpendicular find the slope of the perpensicular points:
AC = 5 +1 / -1 +5 = 6/4 = 3/2
BD = 6+2 / -9 -3 = 8/-12 = -2/3
Because BD is the reciprocal of AC, this means they are perpendicular.
And because AB is not perpendicular to AD ( AB and AD are not reciprocals) it is a rhombus.
