Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Lines AB and CD

NARA [144]

Lines AB and CD are parallel. Using the given coordinates

The equation of line CD is $y=-\frac{1}{4}x+7$

Given :

Lines AB and CD are parallel. The coordinates of point A are (-2,5), the coordinates of point B are (6,3),the coordinates of point D are (8,5)

When two lines are parallel then their slopes are equal

Lets find the slope of AB using the given points

A is (-2,5) and B is (6,3)

Find slope using slope formula

$slope m =\frac{y_2-y_1}{x_2-x_1} =\frac{3-5}{6+2} =-\frac{1}{4}$

Slope of AB is $-\frac{1}{4}$

Slope of AB and CD are same

Slope of CD is $-\frac{1}{4}$

Now we find equation of line CD y=mx+b

Use point slope formula

$y-y_1=m(x-x_1)\\$

use the given point D(8,5) and slope m

Substitute the values

$y-5=-\frac{1}{4} (x-8)\\\\y-5=-\frac{1}{4}x+2\\y=-\frac{1}{4}x+2+5\\y=-\frac{1}{4}x+7$

The equation of line CD is $y=-\frac{1}{4}x+7$

Enter the equation of the line in slope-intercept form.

goblinko [34]

Answer:

y=5x-23

Step-by-step explanation:

Slope-intercept form is: $y=mx+b$

'm' is the slope.

'b' is the y-intercept.

We are given the slope of 5.

We are given a coordinate. (5,2)

We will use the coordinate and the slope to complete the equation.

<h3>Solving The Equation:</h3>

We are already given the slope of five. So, m = 5.

We are given a coordinate. So, to solve the y-intercept, we will use:

x = 5

y = 2

$2=5(5)+b\\\rightarrow5*5 =25\\2=25+b\\\rightarrow 2-25=25-25+b\\\boxed{-23=b}$

So, the y-intercept should be -23.

<h3>Your answer should be:</h3>

$y=5x-23$

Intuitively, does it make sense that all circles are similar? Why or why not?

Allushta [10]

Answer with explanation:

Yes, each point on a circle is a fixed distance from the center of the circle. This is called the radius of the circle. By definition, all radii of a circle are equal.

Similar polygons have corresponding sides in similar proportion. Regardless of how large a circle is, each point on the circle will still be a fixed distance away from center of the circle. Therefore, the radii are in a constant proportional and all circles are similar.

NEED HELP ASAP Solve for x.

dimulka [17.4K]

X=18/5

remove parenthesis -(-2-5x)+(-2)=18

eleminate the opposites 2+5x+(-2)=18

divide both sides by 5 . 5x=18

So the answer would be D

X=18/5
