Answer: Answer is in the steps
Step-by-step explanation:
To determine if their are congruent ,find the distance between the points.
In AB it has the points (-6,-4) and (-1,8)
Now to find the distance you will have to find the difference between the x and y values then square them to add them and find the square root.
-4 - 8 = -12
-6 - (-1) = -5
12^2 + 5^2 =d^2 where d is the distance so solve for d
144 + 25 = d^2
169 =d^2
d = [tex]\sqrt{169}[/tex]
d= 13
So we now the distance of AB is 13
now we need to find the distance between CD
(2,5) (14,0) using these points follow the same steps in the first step to find the distance.
5-0= 5
2 -14 = -12
5^2 + 12^2 = d^2
25 + 144 = d^2
169 =d^2
d = [tex]\sqrt{169}[/tex]
d= 13
So using the information we can say the segments are congruent because they have the same distances .

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?
Answers
Answer:
The conjecture cannot work for any negative numbers, It works for x > 1.3.
Step-by-step explanation:
An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."
It only takes a counterexample to show the conjecture is incorrect.
x^5 -2 ?? x
(-2)^5 -2 ?? (-2)
-32 -2 ?? -2

Distance Traveled and Gas Left in Tank Distance Traveled (in miles) 0 90 180 270 Amount of Gas Left in Tank (in gallons) 15 12 9 6 How many gallons of gasoline does the car have left after it has traveled 330 miles?
Answers
Answer:
4 gallons of gasoline the car has left after it has traveled 330 miles.
Step-by-step explanation:
We are given with the following data of Distance Traveled and Gas Left in Tank below;
Distance Traveled (in miles) Amount of Gas Left in Tank (in gallons)
0 15
90 12
180 9
270 6
330 ?
As we can see from the table that for every 90 miles of distance traveled, there has been a reduction of 3 gallons of gas which is left in the tank, i.e;
From 90 to 180 - Gas reduced from 12 to 9
This means that in 1 gallon of gas, the distance traveled is = [tex]\frac{90}{3}[/tex] = 30 miles
So, from distance 270 to 300, the amount of Gas Left in Tank = 6 - 1 = 5 gallons
From distance 300 to 330 miles, the amount of Gas Left in Tank = 5 - 1 = 4 gallons
Hence, 4 gallons of gasoline is left after the car has traveled 330 miles.

22). VW = 22
23). WY = 20
24). VX = 32
25). WZ = 30
26). VY = 42
Step-by-step explanation:
In the figure attached,
V, W, X, Y and Z are collinear.
VZ = 52, XZ = 20 and WX = XY = YZ
21). Since XZ = 20
XY + YZ = 20
WX + WX = 20 [Since, XY = WX = YZ]
2(WX) = 20
WX = 10
22). VZ = VW + WX + XY + YZ = 52
VW + 3(YZ) = 52 [Since, WX = XY = YZ]
VW + [tex]3(\frac{XZ}{2})[/tex] = 52
VW + [tex]\frac{3}{2}\times 20[/tex] = 52
VW = 52 - 30 = 22

= 32

2 and 3 you have to draw
4a. 90 degree angle
4b. 180 degree angle
5a. 112 degrees
5b. 145 degrees
Step-by-step explanation:
for 5 you just subtract the given values from 360
Answer:
1a) A
(both B and C intersect at A)
1b) not sure
2a) draw 270 degree angle
360/4 = 90
90+90+90 = 270 = 3/4
2b) draw an angle less than 90 degree to get an acute angle
3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees
90/2 = 45
but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it
3b) draw a 90 degree angle facing downward and thats 270 degree
hope you get what im trying to say if not you can ask me again
4a) acute angle (90 degree)
4b) reflex angle (180 degree)
5a) 112 degree
118 + 130 + x = 360
248 + x = 360
x = 360 - 248
x = 112
5b) 145 degree
360 - 215 = 145
im posting the solutions and the answers of your previous questions here
6a) a = 60 degree
6b) b = 27 degree
because sum of interior angles of a triangle is 180
7a) b = 60 degree and a = 30 degree
7b) x = 36 degree and x = 36 degree
isosceles triangle has 2 same angles and 1 different
x + x + 108 = 180
2x + 108 = 180
2x = 180 - 108
2x = 72
x = 72/2
x = 36
8a) x = 95 degree
8b) a = 100 degree
9) steps;
draw a line segment QR
draw 120 degree angle at point Q
now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O
now from point O, open your compass of same measurement and draw an arc that cuts the previous arc
now draw a line from point Q to join the new formed arc
now using a protactor measure both the newly formed angles

Answer:
(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.
Can't read the second question fully.
(A) 0.53
Step-by-step explanation:
Number 1:
If we have the equation [tex]3x + 2 = 5x[/tex], our first goal is to get rid of the x term on one side.
To do this we can subtract 3x from both sides. This leaves our equation to [tex]2=2x[/tex]. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x. This leaves [tex]x=1[/tex].
I couldn't read Number 2 fully - I'm sorry :c
Number 3:
Given the equation [tex]3(x+0.2)=2.2[/tex], we want to isolate x on one side.
To do this, we first apply the distributive property to the left side.
[tex]3x + 0.6 = 2.2[/tex]
Now subtract 0.6 from both sides:
[tex]3x=1.6[/tex]
And divide both sides by 3.
[tex]x=0.5\overline{3}[/tex]
This rounds to 0.53.

Answer:
B
28.78
A
Step-by-step explanation:
Equation
3x + 2 = 5x
The first step is to subtract 3x from both sides.
3x - 3x + 2 = 5x - 3x
2 = 2x
The next step is to divide by two. That's the 2 in front of the two x.
2/2 = 2x/2
1 = x
So the answer must be B
