which equation represents a line that is parallel to the line whose equation is 3x-2y=7; which equation represents a line parall
aleksley [76]

The equation of the line that is parallel to the line whose equation is 3x-2y=7 would be y = 3/2x + b, in which b can be any real number.

How are parallel straight lines related?

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

We have been given a parallel line with has equation

3x-2y=7

In order to solve this, the slope of the original line.

3x - 2y = 7

-2y = -3x + 7

y = 3/2x - 7/2

thus its slope is 3/2.

thus, the slope of the needed line is 3/2 too.

we know that any line that is parallel to that would have this slope.

So anything is written in the form:

y = 3/2x + b

The equation of the line that is parallel to the line whose equation is 3x-2y=7 would be y = 3/2x + b, in which b can be any real number.

Answer: <br> -7(k+9)=9(k-5)-14k
pav-90 [236]
-7(k+9)=9(k-5)-14k
-7k-63=(9k-45)-14k
-7k-63=-5k-45
-7k=-5k+18
-2k=18

castortr0y [4]

Answer:

Two accounts each began with a deposit of $10,000. Both accounts have rates of 6.5%, but one account compounds interest once a year while the other account compounds interest continuously. Make a table that shows the amount in each account and the interest earned after one year, five, years, ten years, and 20 years.

A<em> perpendicular bisector</em> is a straight <u>line</u> drawn at an angle 90^{o} to a given line segment and <em>divides</em> the segment into two equal parts. Thus the appropriate answer to the question is option B. Definition of the <em>perpendicular</em> bisector.

A <u>bisector</u> is a line that divides a given line segment into two equal parts. It is always drawn at a <em>right angle</em> to the given line segment, thus sometimes referred to as a <em>perpendicular bisector</em>.

So in the given question, line CD divides AB into <u>two</u> equal halves and it is drawn at an angle of  90^{o}.

Such that;

<AED = <BED (<u>right </u>angle property)

Therefore, segment CD is a <em>perpendicular bisector</em> of segment AB.

Thus the required answer is option B. Definition of the <em>perpendicular bisector</em>.
