Answer:
-2(9x-8)
Step-by-step explanation:
We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)
Open the parenthesis
-3.1x+7-7.4x-1.5x-6(x-3/2)
= -3.1x+7-7.4x-1.5x-6x+6(3/2)
= -3.1x+7-7.4x-1.5x-6x+9
Collect like terms
= -3.1x-7.4x-1.5x-6x+7+9
= -12x-6x+16
= -18x+16
= -2(9x-8)
Hence the simplified form of the expression is -2(9x-8)
First, we need to make the equation given to be in the form;
y=mx + b
where m is the slope and b is the intercept
8y - 3x = -8
Add 2x to both-side of the equation
8y = 3x - 8
Divide through the equation by 8
y = 3/8 x -1
comparing the above with y =mx + b
m = 3/8
slope of parallel equations are equal
From the options given the only equation with slope 3/8 is;
y= 3/8 x + 8

The above equation of the line is parallel to 8y - 3x = -8
