### Janie uses a reflecting tool to reflect Point B onto Point A. Which of the following statements are true about the line of reflection? 1. Reflection line is perpendicular to AB 2. Reflection line does not bisect AB. 3. Reflection line passes through the midpoint of BA. 4. Reflection line forms two equal angles with segment AB.

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.

D-C-E

DC = 6m - 21
CE = 7m - 18
DE = 65

DC + CE = DE
6m - 21 + 7m - 18 = 65
13m - 39 = 65
13m = 65 + 39
13m = 104
m = 104/13
m = 8

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

The gym charges a beginner's fee of$100 and a monthly fee of $38. If x represents the number of months that LaToya is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time: 100 + 38x = C LaToya has allocated a maximum of$404 to spend on her gym membership. Which number line shows the possible number of months that LaToya can be a member of the gym?

First we know that the maximum of money to spend is \$404. Then we will put it in equation:
100+38 x=404
38 x=404-100
38 x=304
x= 304:38
x= 8

Any line with no slope is parallel to the

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

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

### Points R, S, and T are plotted on a number line. The coordinate of point R is –6. Points S and T are the same distance from point R. What could be the coordinates of S and T? A. S = 0, T = 6 B. S = –4, T = –2 C. S = –9, T = –12 D. S = –10, T = –2

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

### The following lines are parallel. 2x + 6y = 5 and y = 3x + 8 a. True b. False

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.
