QUESTION POSTED AT 18/01/2020 - 01:03 PM

You can understand the concept of reflection by imagining a lake. Suppose a mountain is reflected on the lake across an imaginary horizontal line in the ground. This line is the** Line of Symmetry. **So, in this problem we need to solve four items. Therefore:

**1. Reflection line is perpendicular to AB**

This is **true. **To reflect Point B onto Point A, we need to take a Line of Symmetry perpendicular to the segment AB as illustrated in Figure 1. This line is the one in red and the blue square indicates that the red line and the segment AB are perpendicular.

**2. Reflection line does not bisect AB**

This is **false**. Instead, the line in red bisect the segment AB, that is, it divides the segment into two equal parts as indicated in Figure 2. The **x **in blue represents the point at which the red line bisects the segment.

**3. Reflection line passes through the midpoint of BA.**

This is **true. **Given that the red line divide the segment into two equal parts, then the point at which the red line bisects the segment is also called the* midpoint (M) *as indicated in Figure 3.

**4. Reflection line forms two equal angles with segment AB.**

This is **true. **As you can see in Figure 4, the two blue angles are equal and the two green angles are equal. So, reflection line forms two equal angles with segment AB. In fact, each of these angles measures 90 degrees. Accordingly, all these four angles are equal.

DC = 6m - 21

CE = 7m - 18

DE = 65

DC + CE = DE

6m - 21 + 7m - 18 = 65

13m = 65 + 39

13m = 104

m = 104/13

m = 8

DC = 6m - 21 = 6(8) - 21 = 48 - 21 = 27

Find the equations of the lines in slope-intercept form which is y=mx+b where m=slope b=y intercept

the choices:

0 solutions: means the lines don't intercect at all, meaning same slope but different y intercept or they ar paralell

1 solution: lines intercect in 1 point

2 solutions: curvy line with a straight line thorugh middle

THE ANSWER IS x-axis

Any line parallel to the x-axis has zero slope since there is no rise in the coordinates. The slope is equal to rise over run which means if there is no rise, the slope is zero.

If the point (a,3) lies on the graph of the equation 5x + y = 8, then

THE ANSWER IS a = 1

Simply substitute 3 to y, and solve for x:

5x + 3 = 8

5x = 8 - 3

5x = 5

x = 1

Since the line in question is parallel to the line with the equation 3x+2y-6=0, it can be said that they have the same slope. To find the slope of the line with the given equation, transform the given equation to its corresponding slope-intercept form. Hence, the equation is now

y=(-3/2)x+3

the slope is then -3/2

and since the line in question passes through the origin, the equation of this line is then

y=(-3/2)x+0

or simply

y=(-3/2)x

y=(-3/2)x+3

the slope is then -3/2

and since the line in question passes through the origin, the equation of this line is then

y=(-3/2)x+0

D. S=-10, T=-2 is the answer.

While we check all the given options, we will see that no option other then option D gives us the equal value of difference between R and S, and R and T; which doesn't makes the given value of S and T in option(s) A, B and C equidistant from R as given in the question. Thus, it gives us option D as the answer.

Mathematically-

Considering the option D only,

R - S = -6 - (-10) = -6 + 10 = 4

and, T - R = -2 - (-6) = -2 + 6 = 4

thus, R - S = T - R

To find out whether these lines are parallel or not, we have to calculate the slope. If the slope is same in both equations, then we can say both lines are parallel to each other.

For that purpose, we have to change the format of the equation in this way, y=mx+C.

2x + 6y = 5

y = -1/3 x + 5

y = 3x + 8

Since the slope ( -1/3 and 3 ) of the equations are not equal, these are not parallel to each other.

Answer is b.False
