Answer 1

Answer: 14.
Angles 4 and 6 are supplementary, because they are on the same line. Supplementary angles add up to 180 degrees, and a line must be 180 degrees.

15.
Angles 1 and 8 are congruent, because they are alternate exterior angles

16.
m = y2 - y1 / x2 - x1
m = 7 - 2 / 4 - 5
m = 5 / -1
m = -5

17.
m = 3 - 3 / 7 - (-5)
m = 0 / 12
m = 0

18.
m = 1 - (-2) / 5 - (-4)
m = 3 / 9
m = 1/3

19.
A = (0, 3) - B = (3,0)
m = 0 - 3 / 3 - 0
m = -3 / 3
m = -1
C = (0, -2) - D = (4, 2)
m = 2 - (-2) / 4 - 0
m = 4 / 4
m = 1
Perpendicular, because the slopes are opposite reciprocals.

20.
E = (1, 2) - F = (0, 0)
m = 0 - 2 / 0 - 1
m = -2 / -1
m = 2
G = (1, -3) - H = (3, 0)
m = 0 - (-3) / 3 - 1
m = 3 / 2
Neither, because the slopes are different.

21.
I = (0, 1) - J = (2, -4)
m = -4 - 1 / 2 - 0
m = -5/2
K = (-1, -2) - L = (4, 0)
m = 0 - (-2) / 4 - (-1)
m = 2/5
Perpendicular, because the slopes are opposite reciprocals.

22.
M = (-2, 2) - N = (2, 2)
Horizontal line
m = 0
O = (3, 0) - P = (-3, 0)
Horizontal line
m = 0
Parallel, because the slopes are the same.

23.
Angle 2 is congruent to angle 1 because of the alternate exterior angle theorem.
Angle 1 is congruent to angle 3 because of the vertical angle theorem.
Angle 2 is congruent to angle 3 because of substitution.
Line l is parallel to line m because the corresponding angles are congruent.

Answer 2

Answer: 14. Supplementary
15. Congruent

16. $m = (y_2 - y_1)/(x_2 - x_1) = (7 - 2)/(4 - 5) = (5)/(-1) = -5 \n\ny - y_1 = m(x - x_1) \ny - 2 = -5(x - 5) \ny - 2 = -5(x)+ 5(5) \ny - 2 = -5x + 25 \ny = -5x + 27$

17. $m = (y_2 - y_1)/(x_2 - x_1) = (3 - 3)/(-5 - 7) = (0)/(-12) = 0 \n\ny - y_1 = m(x - x_1) \ny - 3 = 0(x - 7) \ny - 3 = 0(x) - 0(7) \ny - 3 = 0x - 0 \ny = 0x + 3$

18. $m = (y_2 - y_1)/(x_2 - x_1) = (1 - (-2))/(5 - (-4)) = (1 + 2)/(5 + 4) = (3)/(9) = (1)/(3) \n\ny - y_1 = m(x - x_1) \ny - (-2) = (1)/(3)(x - (-4)) \ny + 2 = (1)/(3)(x + 4) \ny + 2 = (1)/(3)(x) + (1)/(3)(4) \ny + 2 = (1)/(3)x + 1(1)/(3) \ny = (1)/(3)x - (2)/(3)$

19. Perpendicular
20. Neither
21. Perpendicular
22. Parallel

23. Given: Transversal r cuts lines
   l and m: <2 = <1
      Prove: l || m

Statements | Reasons
1. <2 ≡ <1 | 1. They are congruent.
2. <1 ≡ <3 | 2. They are congruent.
3. <2 ≡ <3 | 3. They are parallel.
4. l || m    | 4. They are parallel.

Which of the following is equivalent to 18- √25?
5i
18 – 5i
18 + 5i
23

Answers

In this complex number, assuming that the equation actually is 18- √-25, the real part is already simplified. However, the imaginary part can be simplified by taking out "i" from the root using the relation i = √-1. This is done below:

18 - √-25
18 - √(-1)(25)
18 - 5i

From the choices, the correct answer is 18 - 5i.

Answer:

The answer is B

Step-by-step explanation:

The distance between the school and the house of a student living in a village is 2km 125m. Every day he covers the distance both ways by walking. Find the total distance covered by him in 4 days.

Answers

Answer:

17,000m

or 7 km

Step-by-step explanation:

distance covered in 4 days = total distance x 2 x 4 days

convert the total distance to meters

(1000m x 2) + 125 = 2125m

total distance = 2125 x 2 x 4 = 17,000m or 7km

Answers

1 minute = 60 seconds
1 hour = 60 minutes = 3600 seconds
1 day = 24 hours = 1440 minutes = 86400 seconds
2.6 day = 2.6 * 86400 seconds = 224 640 seconds

Are the equations a/b=c/d and ad=bc equivalent? Explain.

Answers

Step-by-step explanation:

The relation given is a/b = c/d, if we cross multiply we will get ad = bc which we got from the first relation only. Let's take an example and assign a,b,c,d some numbers.

We know, 1/2 = 3/6 (equivalent fractions). Then a = 1, b = 2, c = 3, d = 6. Now put these values into the 2nd relation,

ad = 1 * 6 = 6
bc = 2 * 3 = 6

ad = bc relation is satisfied. Hence the equations a/b = c/d and ad = bc equivalent $.$
