which equation describes the motion of the train?
d=50t
d=25t
d= t- 175
d= t + 25
Answer:
d = 25t
Step-by-step explanation:
pick tow points on the line, the easier for me is (0,0) and (2,50). The equation options are given in slope intercept form such as y = mx + b; where m is the slope and be is where the line intercepts the y-axis. We can see that "b" is zero because the line intercepts the y-axis at 0 (b = 0).
to find the slope you use the two points for the m
m = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex] = [tex]\frac{(50 - 0)}{(2 - 0)}[/tex] = 25 is the slope
Therefore the equation should d = 25t

PLEASE HELP!! THANK YOU!!
Step-by-step explanation:
i know the coordinates are ( 0,-3 1/2 ) or ( 0, -3.5 ) for D
Answer:
(0,-2)
Step-by-step explanation:
Parallelograms have parallel lines and equal opposite lines.
You can count.
For Ex: A is 1 above and 5 to the left of B.
So D should be 1 above and 5 to the left of C.
C is at (5,-3)
Go up 1 and left 5 and you get (0,-2)
Please help! 2nd time asking!
Answer:
4
Step-by-step explanation:
Function 1 is moving at a constant rate meaning it has the rate of change of 0/1 or 0.
Function 2 says y is 4x meaning that the rate of change is 4/1 or 4.
0 - 4= I-4I or 4

What is the best description of slope (m) in a word problem?
The total at a certain time
The starting point
The rate of change
The amount of time
Answer:
Word problems with linear equations (that is, with straight-line models) almost always work this way: the slope is the rate of change, and the y-intercept is the starting value.

Please answer! solve for x
Answer:
it 180 degree try to add them all the subtract with 180 and that equals x
Step-by-step explanation:
Answer:
x = -10
Step-by-step explanation:
The angles of a triangle always add up to 180°. This means that (x+46) + 52 + 92 = 180.
First, subtract 92 from both sides of the equation to get (x+46) +52 = 88. Then, subtract 52 from both sides of the equation to get x + 46 = 36. Finally, subtract 46 from both sides of the equation to get x = -10

The total cost in dollars to buy uniforms for the Ping-Pong team can be found using the function c=22.50+5 where u is the number of uniforms bought.if there are at least 7 players but not more than 10 players on the Ping-Pong team, what is a reasonable range for the situation? A.{7,8,9,10} B.{162.50 , 185, 207.50, 230} C. 7≤ x ≤ 10 D. 162.50 ≤ y ≤ 230
answer: b
explanation:
it’s asking for the range so it can’t be c or d because those are used in continuous data only so it’s between a and b but it can’t be a as a is the range of players but b is the range of the cost so the answer would then be b

Felix’s Feed Mill sells chicken feed for $8.00 per bag. This price is no longer high enough to create a profit. Felix decides to raise the price. He is considering four different plans.
Plan A: Raise the price by $0.10 each week until the price reaches $12.00.
Plan B: Raise the price by 10 percent each week until the price reaches $12.00.
Plan C: Raise the price by the same amount each week for 8 weeks, so that in the eighth week the price is $12.00.
Plan D: Raise the price by $0.25 each week until the price reaches $12.00.
Which plan will result in the price of the feed reaching $12.00 fastest?
-plan A
-plan B
-plan C
-plan D
Answer: B is the fastest way
Step-by-step explanation: How to solve this is a bit hard
8*1.1^n =12, so : ln(8) +n*ln(1.1) = ln(12), then
n = (ln(12) - ln(8))/ln(1.1) (≈ means around)4.3 weeks.

Step-by-step explanation:
A water taxi travels around an island in a path that can be modeled by the equation y =0.5(x - 16). A water skier is skiing along a path that begins at the point
(6,6) and ends at the point (8. - 4).
a. Write a system of equations to model the problem.
b. Is it possible that the water skier could collide with the taxi? Explain
I realize that the equation is different, but do it in the same way, it'll help! It is given that the water taxi's path can be modeled by the equation y =0.5(x - 14)^2. Therefore, this is one of the equations in this system. Find a linear equation that will model the path of the water skier, which begins at the point (6,6) and ends at the point (8,-4). The slope is (-5). Use the slope and one point on the line to find the y-intercept of the line. The y-intercept of the line that passes through the points (6,6) and (8,-4) is (0,36). Thus, the equation is y=-5x+36. Now, to determine if it is possible for the water skier to collide with the taxi, we have to determine if there is a solution to the system of equations. To determine if there is a solution to the system of equations, solve the system using substitution. First, write the equation that models the water taxi's path in standard form. y=0.5(x - 14)^2-->0.5x^2-14x+98. Use substitution. Substitute for y in the equation and then solve for x. As the expression on the left side of the equation cannot easily be factored, use the Quadratic Formula to solve for x. Do x=-b(plusorminus)sqrrtb^2-4ac/2a. Identify a, b, and c. a=0.5, b=-9, and c=62. Substitute into the Quadratic Formula. If there is a negative number under the radical, there are NO solutions. Thus, the path of the water skier will never cross the path of the taxi.
In conclusion: It is not possible that the water skier could collide with the taxi as the two paths never cross.
