Answer:
The lines are parallel
Step-by-step explanation:
When lines are parallel they travel side-by-side without ever crossing paths.
Answer: Parallel

Step-by-step explanation:
16. Find the length of the median CD.
17. Find the coordinates of E, the midpoint of BC
18. Find the length of the median AE.
Step-by-step explanation:
16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)
C (2,-3) D (6,3)
CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)
CD = sqaureroot of ( 16 + 36)
CD = sqaureroot of 52 = 2 root 13 = length
17. E (5, - 1) because the point is under the x axis.
Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)
B (8,1) C (2, - 3)
Midpoint of BC = ((2+8)/2 , (-3+1)/2)
= (10/2 , - 2/2)
= (5, - 1)
18. Length of AE
A (4,5) E(5,-1)
Square root of ((5-4)^2 + (-1-5)^2)
Square root of (1^2 + - 6^2)
Square root of ( 1 + 36)
Square root of 37 = root 37

Answer:
The perimeter of the rectangle is 27n + 1 feet
Step-by-step explanation:
The formula of the perimeter of the rectangle is P = 2(L + W), where
L is the length of the rectangleW is the width of the rectangle∵ The width of a rectangle is 7n - 6.5 feet
∴ W = 7n - 6.5 feet
∵ The length of the rectangle is 6.5n + 7 feet
∴ L = 6.5n + 7 feet
→ Substitute W and L in the formula of the perimeter above
∵ P = 2[6.5n + 7 + 7n - 6.5]
→ Add the like terms
∴ P = 2[(6.5n + 7n) + (7 - 6.5)]
∴ P = 2[13.5n + 0.5]
→ Multiply the terms in the bracket by 2
∴ P = 27n + 1
∴ The perimeter of the rectangle is (27n + 1) feet
find the measure of angle 1
Answer:
[tex]\displaystyle 70° = m\angle{1}[/tex]
Step-by-step explanation:
Consecutive Interiour Angles are supplementary, so set both expressions equivalent to one hundred eighty degrees:
[tex]\displaystyle 180° = [9x + 38]° + [6x + 22]° \hookrightarrow 180° = [60 + 15x]° \hookrightarrow \frac{120}{15} = \frac{15x}{15} \\ \\ 8 = x \\ \\ \\ [6[8] + 22]°; [48 + 22]° \\ \\ 70° = m\angle{4}[/tex]
As you can see, we plugged the x-value into the expression for the fourth angle because if you recall, you can tell that angles [tex]\displaystyle 1\:and\:4[/tex]are vertical angles, and accourding to the Vertical Angles Theorem, these angles are considered congruent, therefore seventy degrees is also the measure of the first angle.

An angle measures 72.2° less than the measure of its complementary angle. What is the
measure of each angle?
º and°
Answer:
We have the angles as;
8.9 and 72.2
Step-by-step explanation:
When two angles are complementary, they add up to 90
Let the first angle be x , the second angle is 72.2 degrees less and it is x-72.2
Thus, mathematically;
x + x - 72.2 = 90
2x = 90+ 72.2
2x = 162.2
x = 81.1
x = 81.1
The other will be
81.1 - 72.2 = 8.9
If the 2 in 506,092 moved 2 places to the right what would it b
Answer:
The two will retain its unit place value
Step-by-step explanation:
We are given the number 506,092
Which is stated in words as
"Five hundred and six thousand and ninety two"
2 represents 2 units in the number
When we shift 2 by two places to the right, the number becomes
50,609,002
We can still see that "two" still retains it unit place value and the whole number now reads fifty million six hundred and nine thousand and 2

Step-by-step explanation:
you just need to add both equations
you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Answer:
(-2,6)
Step-by-step explanation:
3x + 2y = 6
-3x + y = 12
3x + -3x = 0
2y + y = 3y
6 + 12 = 18
3y = 18
3y/3 = 18/3
y = 6
-3x + y = 12
-3x + 6 = 12
-3x = 12 - 6
-3x = 6
-3x/-3 = 6/-3
x = -2

Use the Law of Logarithm to expand the expression. ln(y √x/z (I know the answer is 2ln(y)+ln(x)-ln(z) all over 2, but I need the steps to get there)
Answer:
[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
Step-by-step explanation:
From the question we are told that the expression [tex]ln(y √x/z[/tex]
[tex]in (y\sqrt{\frac{x}{y}})[/tex]
[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]
[tex]in(xy)=in(x)+in(y)[/tex]
[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]
[tex]in(xy)=\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
Mathematically
[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]
