Answer:
parallel
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slopes m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)
m = [tex]\frac{3-2}{2+1}[/tex] = [tex]\frac{1}{3}[/tex]
Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)
m = [tex]\frac{1-0}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]
Since slopes are equal then parallel

2.Jasmine drives every morning to her office that is 12 miles from her home.
If Jasmine's average driving speed is s mph, how many minutes does it take her to reach the office
3.Jasmine drives every morning to her office that is 12 miles from her home.
Suppose Jasmine drives from home to the office in 20 minutes. Use this information and part (b) to write an equation.
4.Jasmine drives every morning to her office that is 12 miles from her home.
* What is Jasmine's driving speed in mph?
Solve the equation you created in part (c) to answer the question.
Answer:
1. Her time in minutes is 720/s minutes
2. Given her time to be 20 minutes, her speed is 36 mph
Step-by-step explanation:
Mathematically,
Distance = speed * time
In this question, we want to calculate time;
So time = distance/speed
times = 12 miles/s mph = 12/s hours
Now we want our answer in minutes
Kindly recall that 60 minutes = 1 hour
So 12/s hours will be 12/s * 60 = 720/s minutes
2. Since she drives from home to the office in in 20 minutes, we want to calculate her speed in mph
From the time calculated above i.e 720/s
We can equate 20 = 720/s
20s = 720
s = 720/20
s = 36 mph

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
Answer:
x=18.5
y=37
Step-by-step explanation:
90+2y+16=180
106+2y=180
2y=74
y=37
16+4x+90=180
106+4x=180
4x=74
x=18.5
Answer:
y = 37, x = 18.5
Step-by-step explanation:
O = 16 because of the vertical angles rule. The degrees on a straight line is 180 degrees. That means that because AB is a straight line, 2y + O + 90 = 180. We also know that CD are straight, so O + 4x +90 = 180.
Now we solve for x and y:
2y + O + 90 = 180
2y + 106= 180
2y = 74
y = 37
O + 4x +90 = 180
16 + 4x +90 = 190
4x + 106 = 180
4x = 74
x = 18.5

What is the final price of the four-night reservation
representing a better deal?
You are a travel agent. A customer requires a hotel
reservation for four nights. You are considering two
hotels. The first usually charges $168 per night, including
all taxes and fees, but will give a discount of $40 per
night. The second charges $185 per night, including all
taxes and fees, and will offer one night for free.
O $504
O $512
O $555
$580
O $672
Answer:
$512
Step-by-step explanation:
Charges at the first hotel are ...
4(168 -40) = 4(128) = 512
Charges at the second hotel are ...
(4-1)(185) = 3(185) = 555
The first hotel offers the better rate: $512 for four nights.

Point A is the midpoint of side XZ and point B is the midpoint of side YZ. Triangle X Y Z is cut by line segment A B. Point A is the midpoint of side X Z and point B is the midpoint of side Y Z. The length of X Y is 5 x minus 7, the length of A B is x + 1, and the lengths of X A and Z A are 2 x minus 2. The lengths of Y B and B Z are congruent. What is AX? 2 units 4 units 6 units 8 units
Answer:
B. 4unitsStep-by-step explanation:
Find the diagram attached. The diagram is a similar triangle.
From the diagram, XZ/XY = CA/AB
Given XZ = 2x-2+2x-2 = 4x-4
XY =5x-7
CA = 2x-2
AB= x+1
On substituting this parameters into the formula to get x first
4x-4/5x-7 = 2x-2/x+1
cross multiply
(4x-4)(x+1) = 5x-7(2x-2)
open the parenthesis
4x²+4x-4x-4 = 10x²-10x-14x+14
4x²-4 = 10x²-24x+14
10x²-4x²-24x+14+4 = 0
6x²-24x+18 = 0
x²-4x+3 = 0
x²-3x-x+3 = 0
x(x-3)-1(x-3) =0
(x-3)(x-1) = 0
x = 3 and 1
Next is to get length AX.
Given AX = 2x-2
Substitute x = 3 into the expression
AX = 2(3)-2
AX = 6-2
AX = 4 units
Hence the measure of length AX is 4 units

Suppose A and B are points. What is the maximum number of distinct lines that contain both A and B?
Answer:
Step-by-step explanation:
there would be one distinct line
Points and lines are both undefined terms of geometry.
The maximum number of distinct lines that contain both A and B is 1
From the question, we have:
[tex]Points = 2[/tex] --- i.e. A and B
For any given 2 points, only one line can run through the points. In other words, only one line can run through point A and point B
The line can:
Start from point A and end at point BStart from point B and end at point BRun through both pointsHence, the maximum number of distinct lines that contain both A and B is 1

What is an exponential function?In Mathematics, an exponential function can be modeled by using this mathematical expression:
f(x) = ab^x
Where:
a represents the initial value or y-intercept.x represents time.b represents the rate of change.Based on the information provided above, an exponential function which models the situation is given by:
y = 200,000(1.09)^x
For the time between May 7 and May 21, we have:
Time = May 7 to May 21 = 15 days.
Substituting the given parameters into the exponential function formula, we have;
y = 200,000(1.09)^15
y = 200,000(3.6425)
