Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.

Answer:
L= 90, M=53, K=37
Step-by-step explanation:
Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

Answer:
The third one. A trend line does describe data patterns.
eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily: part a: describe the relationship between the temperature of the city and the number of cups of lemonade sold part b: describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. show your work, including the points that you use to calculate the slope and y-intercept.
Answer:
part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade
part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b
90=25/6(1)+b
90/1=25/6+b
25/6 25/6
and then B= 21.6
Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol
Can someone tell me the equation of this graph
1. f(x)=1/4x + 4
2. y=1/2x + 4
3. y=2x + 4
4. f(x)= - 2/3x + 4
Answer:
3. y=2x + 4
Step-by-step explanation:
We know that b is 4 because of the point (0,4)
Now count the slope by using rise over run
We go up 2 and over 1 so the slope is 2

Please help me I’ll give you 100 points
Answer and Step-by-step explanation:
So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.
Now, the semicircles. They together form a circle.
So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852
Now we add them together.
99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)
The rectangle area is 3180.
The Semi circles' combined area is 99.85.
The total area of the figure is 3279.85.
I hope this helps! Have a great day!
#teamtrees #PAW (Plant And Water)
Answer:
3973.82Step-by-step explanation:
to understand thisyou need to know about:geometryPEMDASlet's solve:there are a rectangle and a full circleaccording to the question
the area of full shape
=[tex]\text{area of the rectangle+the area of the full circle}[/tex]
=(100×31.8)+(π×(31.8/2)²)
=3180+(3.14×(15.9)²
=3180+(3.14×252.81)
=3180+793.8234
=3973.8234
=3973.82
1) What is the product of (3x + 2) and (x - 7)?
2) What are the factors (multiplier) of 3x2 − 9x ?
Answer both of the questions
Answer:
1) [tex]3x^{2}[/tex]-19x-14
2) x=0, x=3
Step-by-step explanation:
1) (3x+2)(x-7)
Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.
[tex]3x^{2}[/tex] - 21x + 2x -14
Combine like terms
[tex]3x^{2}[/tex] - 19x - 14
2)
In order to find the factors of x, set the expression equal to 0.
[tex]3x^{2}[/tex] - 9x = 0
Factor out the highest common multiple (3x)
3x(x-3) = 0
In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3
Or 3x = 0 -> x = 0

show your work
Answer:
Step-by-step explanation:
First you would make the equation
(1/2x - 1/4)(5x^2 + 6)
afterwards you would multiply like normal binomials\
5/2x^3 + 3x - 5/4x^2 - 6/4
Then simplify
5/2x^3 - 5/4x^2 + 3x - 3/2
Remember to put them in order from the most roots to the least.

2 (3x - 5) + 4 = -18
Solve for 20 Points
Answer:
x = -2
Step-by-step explanation:
2(3x - 5) + 4 = -18
Distribute the 2
6x - 10 + 4 = -18
6x - 6 = -18
Add 6 to both sides
6x = -12
Divide both sides by 6
x = -2
Check:
2(3x - 5) + 4 = -18
substitute x = -2 into the original equation
2(3(-2) - 5) + 4 = -18
2(-6 - 5) + 4 = -18
2(-11) + 4 = -18
-22 + 4 = -18
-18 = -18
So x = -2 is true.
Answer:
x=-2
Step-by-step explanation:
2(3x-5)+4=-18
We move all terms to the left:
2(3x-5)+4-(-18)=0
We add all the numbers together, and all the variables
2(3x-5)+22=0
We multiply parentheses
6x-10+22=0
We add all the numbers together, and all the variables
6x+12=0
We move all terms containing x to the left, all other terms to the right
6x=-12
x=-12/6
x=-2
