You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.
Let x = the number of miles traveled and y = the total cost for the trip.
If a trip is 8 miles, which company would be the better choice? Show the work that leads to your answer.
Answer: the answer is uber.
Step-by-step explanation: Uber: 3 + 2 = $5.00 total
Lyft: = 6 dollars total

Answer:
11 units perhaps you rise 6 and run 5. 6+5=11
Step-by-step explanation:
The following examples illustrate the inverse property of multiplication. Study the examples, then choose the statement that best describes the property.
1/5 • 5 = 1
√2 ( 1/√2 ) = 1
Inverse property of multiplication: For all real numbers except
? , a • = 1.
Answer:
Zero!!
Zero can't be divided and when multiplied, will result 0.

Which equation is represented by the table?
Answer:
D. 3x - 1
Step-by-step explanation:
y = mx + b
We see the point (0, -1), so b = -1
y = mx - 1
We can find the slope using 2 points such as (0, -1) and (1, 2).
m = (2 - (-1))/(1 - 0) = 3
y = 3x - 1
Answer: D. 3x - 1
I need help solving 16 and 17
Please explain reasoning!
Answer:
16. Square
17. Rectangle
Step-by-step explanation:
16. All of the sides are equal and all of the angles are equal at 90° each
17. The longer sides are equal to each other and the shorter sides are equal to each other. The angles are all equal and and are all equal at 90° each.
Hope this helps!
How many solutions does the system have?
x + y = 5
x + y = 6
- none
- one
- two
- infinite
Answer: no solution
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
In order for the system to have solutions, x and y must work for both equations.
The easiest way to solve this is the isolate the y variable on both equations and then solve for x:
1. x+y=5
y=5-x
2. x+y=6
y=6-x
Since the y variables for both equations should be the same, let us make a new equation:
6-x=5-x
6=5
Hmm... This doesn't seem to work! 6 does not equal to 5. Therefore, there are no solutions.
I hope this helps! Please let me know if you have any further questions :)

Length: 16m
Width: 12m
Area: 192 square meters
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
Length-16m
Width-12m
Area-192m
Step-by-step explanation:
Formula- 3cm=4m
12/3=4
4x4=16
Length-16m
9/3=3
3x4=12
Width-12m
16m x 12m = 192m

Answer:
Scale factor = 2, x = 3 cm
Step-by-step explanation:
The scale factor is 2 because you can see that in the second figure you multiply the sides from the first one by 2.
Using the scale factor 2, you can multiply 1.5 * 2 = 3 for x.
A right triangle has legs of 18 inches and 24 inches whose sides are
changing. The short leg is increasing by 4 in/sec and the long leg is
shrinking at 9 in/sec. What is the rate of change of the hypotenuse?
Given:
A right triangle has legs of 18 inches and 24 inches.
The short leg is increasing by 4 in/sec and the long leg is shrinking at 9 in/sec.
To find:
The rate of change of the hypotenuse.
Solution:
Let x be the shorter leg (Base), y be the larger leg (Perpendicular) and z be the hypotenuse.
We have,
[tex]\dfrac{dx}{dt}=4\text{ in/sec}[/tex]
[tex]\dfrac{dy}{dt}=-9\text{ in/sec}[/tex]
[tex]x=18[/tex]
[tex]y=24[/tex]
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex]z^2=x^2+y^2[/tex] ...(i)
[tex]z^2=(18)^2+(24)^2[/tex]
[tex]z^2=324+576[/tex]
[tex]z^2=900[/tex]
Taking square root on both sides.
[tex]z=\pm \sqrt{900}[/tex]
Side cannot be negative. So,
[tex]z=30[/tex]
Differentiating (i) with respect to time t, we get
[tex]\dfrac{d}{dt}z^2=\dfrac{d}{dt}(x^2+y^2)[/tex]
[tex]2z\dfrac{dz}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}[/tex]
[tex]2(30)\dfrac{dz}{dt}=2(18)(4)+2(24)(-9)[/tex]
[tex]60\dfrac{dz}{dt}=144-432[/tex]
[tex]60\dfrac{dz}{dt}=-288[/tex]
Divide both sides by 60.
[tex]\dfrac{dz}{dt}=\dfrac{-288}{60}[/tex]
[tex]\dfrac{dz}{dt}=-4.8[/tex]
Here, negative sign means hypotenuse is decreasing.
Therefore, the hypotenuse is shrinking at 4.8 in/sec.

Question 3 cdhcjenfheucjndjdnd
Answer:
Slope 3, y-intercept is 1
Step-by-step explanation:
As x increases by 3, y increases by 9. Rate of change is y/x, therefore the slope is 9/3 which equals 3. If the slope is 3, to find y, simply subtract 9 from 10. 10-9 = 1.
Answer:
y=3x+1
Step-by-step explanation:
slope is 3
intercept is 1

if the diameter of the concentric circles as shown in the given figure are in the ratio 1:2:3 then find the ratio of the areas of three regions
Answer:
1 : 4 : 9
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9
