Answer;

C) The second arc should be centered at C.

Assuming the goal is to construct a line parallel to AB that passes through given point C.

-Draw a line through C and across AB at an angle creating D.

- With the compass width about half of DC, and center D, draw the first arc to cross b

When is the additive relationship used? Select all that apply.

Mrac [35]

Answer:

your answer is for sure D but I think C is also the answer

Step-by-step explanation:

Additive relationship are two quantities can be expressed as related to each other through addition. It can be written as y = x + a, where y is related to x through the addition of a constant, a. The value for a may be positive or negative.

Using the given points and line, determine the slope of the line. (-3, 0) and (2, 7)

Nuetrik [128]

Slope for (x₁, y₁) and (x₂, y₂): (-3, 0) and (2, 7)

Slope: (y₂ -y₁) / (x₂ -x₁)

Slope: ( 7 - 0) / (2 - -3) = 7/(2 + 3)

<span>Slope = 7/5

Q4: Write the equation in slope-intercept form of the line that is perpendicular to

forsale [732]

Answer:

5y = x + 11

Step-by-step explanation:

Given parameters:

Equation of the line ;

y = -5x + 1

Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

y = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

So, the slope of the new line perpendicular is $\frac{1}{5}$ ;

Now let us find the y-intercept of the new line;

x = -1 and y = 2

2 = $\frac{1}{5}$ x (-1) + c

c = 2 + $\frac{1}{5}$ = $\frac{11}{5}$

The equation of the new line is;

y = $\frac{1}{5}$ x + $\frac{11}{5}$

or multiply through by 5;

5y = x + 11
