Answer:

The answer is A. 0.1x + 18.2

Step-by-step explanation:

We have to simplify the expression

We will use distributive Property of Multiplication with respect to Addition and Subtraction

⇒3×(2.7 x +5) -2 ×(4 x -1.6)

=3×2.7 x +3×5-2×4 x-2×(-1.6)

=8.1 x +15 -8 x+3.2

=(8.1 x- 8 x)+15+3.2-----Adding and Subtracting like terms

= 0.1 x +18.2

The line with equation y=my+b is perpendicular to the line with equation y=16 - x/3. The value of m is ____?

sweet-ann [11.9K]

Answer:

m=3

Step-by-step explanation:

Perpendicular lines intersect at 90 degrees or perpendicular angles. As such, their slopes are related. The slope of each line is the negative reciprocal of the other. For the equation, $y=16-\frac{x}{3}$ . The slope or $m=-\frac{1}{3}$ . This means the slope of the other line will be the negative reciprocal which is -(-3)=3
