find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points
(x, y, z) = (k, 0, 0) + α (0,0,1) - this is the equation is parallel to the z-axis and passes through the midpoint between the two points.
What is slope of a parallel line?The slant of a line is registered as for the positive x-hub and the equal lines are similarly disposed regarding the positive x-pivot. At the point when planets are a similar distance yet on inverse sides of the divine equator they are alluded to as being contra-equal. The equal lines are similarly disposed with the positive x-pivot and thus the incline of equal lines is equivalent. Equal lines and their inclines are simple. Since incline is a proportion of the point of a line from the level, and since equal lines should have similar point, then equal lines have similar slant and lines with a similar slant are equal. Opposite lines are somewhat more muddled.

In ∆ABC the angle bisectors drawn from vertices A and B intersect at the point D. Find m∠ADB if: m∠A = α, m∠B = β
The angle at D which is m∠ADB is calculated to be 180 - ( α + β ) / 2
How to find < ADBGiven data
< A = α
∠ B = β
Angle bisectors divides the given angle into two and form a triangle which is ∆ADB
The angles that form ∆ADB are as follows
< A = α / 2
∠ B = β / 2
to find < D we use sum of angles in a triangle which is 180 degrees and solve as follows
< A + < B + < D = 180 degrees
where < D = m∠ADB, substituting the other values gives
α / 2 + β / 2 + < D = 180
( α + β ) / 2 + < D = 180
< D = 180 - ( α + β ) / 2
Since < D = m∠ADB .We can therefore say that m∠ADB = 180 - ( α + β ) / 2

Bart found 20 quadrilaterals in his classroom. He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (E) and those with four right angles (R). Circles E and R overlap. Circle E contains 3, circle R contains 6, and the intersection contains 2. Number 9 is outside of the circles. Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? Express your answer in percent form, rounded to the nearest whole percent. 25% 33% 40% 67%
Answer:
A. 25%
Step-by-step explanation:
The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is 25%
What are quadrilaterals?Quadrilaterals are shapes that have four sides; these four sides may or may not be:
ParallelCongruentCheck below on how to determine the probability
From the question, we have the following parameters:
n(E) = 5n(R) = 8n(E and R) = 2None = 9n(U) = 20The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is calculated using:
P(E | R) = n(E and R)/n(R)

HELPPPP FIND VALUE OF Y !!!
Answer:
Y=13
Step-by-step explanation:
X is 45 so
45+5y+5=9y-2 solve and y=13
Answer:
y = 13
Step-by-step explanation:
x + 135 = 180 {linear pair}
x = 180 - 135
x = 45
9y - 2 = 5y + 5 + x {Exterior angle property of triangle}
9y - 2 = 5y + 5 + 45
9y - 2 = 5y + 50 {Subtract 5y from both sides}
9y -5y -2 = 50
4y - 2 = 50 {Add 2 to both sides}
4y = 50 + 2
4y = 52 {Divide both sides by 4}
y = 52/4
y = 13

Tia used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy:
The ratio of DA:HE is 1:2. What is the length, in meters, of side FG on the photocopied image?
14
17
28
34
Answer:
I think its 28.
Step-by-step explanation: Dont take my word for this tho
the ratio is 1:2 and that would mean that whatever length DA, HE is 2 times.
The length of BC is 14 so 14 x 2 is 28.
The length, in meters, of side FG on the photocopied image is 28 m and this can be determined by using the concept of dilation.
Given :
Tia used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy.The ratio of (DA : HE) is 1:2.AB = 17 mBC = 14 mThe following steps can be used in order to determine the length, in meters, of side FG on the photocopied image:
Step 1 - According to the given data, the side length of DA is 2 times the side length of HE.
Step 2 - From the above step, it can be concluded that 2 is the dilation factor.
Step 3 - From the given data, the length of BC is 14m. So, the length of the side FG is given by:
FG = 2 BC
Step 4 - Substitute the value of length of side BC in the above expression.
FG = 2(14)
FG = 28 m
Therefore, the correct option is C).

Jordan is starting to save $150 to buy a new cell phone. In December, he saved $5. In January, he plans twice as much as he did in December, for a total savings of $15 ($5 + $10). If Jordan continues to save twice as much he saved from the previous month, in which month will his total savings will be enough to buy the phone.
Answer: At the Month May Jordan as able to get enough money to buy the phone.
Work:
December:$5
January:$10
February:$20
March:$40
April:$80
May:$160 <--Answer
____________________________________________________________In the problem Jordan saves $5 at December, then at January Jordan saved $10 which is twice as December's saved money amount. February, Jordan saved $20, which is twice as January's saved money amount. March is $40, which is twice as February's saved money amount. For April it is $80, which is twice as March's money amount, May is $160 which is twice as April's money amount. Or another way to say this is by starting at $5. Then, keep multiplying by 2 for each month until you get $150 or more. When you do, stop at the month that gets you $150 or more. When i did this exact method, I got $160 on the Month of May. $160 is more than enough for Jordan to buy his phone. So the month May is the correct answer where Jordan can get enough money for his phone.
Answer: The fifth month; By April Jordan would have saved more than enough to buy a new phone.
Step-by-step explanation:
Dec $5
Jan $10

Students will randomly select a tile from a bag containing one red, one yellow, one blue, and one green tile, and then roll a cube with faces numbered 1 through 6. What is the probability that a student draws a red or yellow tile, and rolls a number between 1 and 3.
Answer:
[tex]\bold{\dfrac{1}{4}}[/tex]
Step-by-step explanation:
Number of red tiles = 1
Number of yellow tiles = 1
Number of blue tiles = 1
Number of green tiles = 1
Total number of tiles = 4
Also, given that there is a standard dice with faces numbered from 1 to 6.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
First of all, let the event [tex]A[/tex] be event that a red or yellow tile is chosen.
Number of favorable cases = 2
Total number of cases = 4
[tex]P(A) = \dfrac{2}{4} = \dfrac{1}{2}[/tex]
Let the event [tex]B[/tex] be event that a number between 1 and 3.
Number of favorable cases = 3
Total number of cases = 6
[tex]P(B) = \dfrac{3}{6} = \dfrac{1}{2}[/tex]
[tex]P(A\ and\ B) = P(A).P(B)[/tex]
[tex]P(A\ and\ B) = \dfrac{1}{2}.\dfrac{1}{2} = \bold{\dfrac{1}{4}}[/tex]
