1.468*3.14 is around 4.6 so B)
And 65.97/4.6 is about 14.3 so C)
· Perpendicular lines have slopes that are opposite reciprocals of each other
· Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept
If the slope of the first line is 3, the slope of the second line is -1/3. Since the lines intersect at the origin, neither of them have a y-intercept.
Answer:
C) y = -1/3x

54a+24ab-10a

4a (11+6b)
Answer:
<h3>√(1-a)²+(b+2)²</h3>
Step-by-step explanation:
If the pipe on the plan runs from point N(a, -2) to point P(1, b), the expression that represents the shortest distance between N and P in units, is expressed using the formula;
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates N(a, -2) and P(1, b);
x₁ = a, y₁ = -2, x₂ = 1 and y₂ = b
NP = √(1-a)²+(b+2)²
<em>Hence the expression that represents the shortest distance between N and P in units is √(1-a)²+(b+2)² units</em>
