II. The train and roller coaster will arrive back at their stations at the same time. If the train had a .15 mile head start and is traveling at a speed of .65 miles per minute, and the roller coaster is travelling at an average speed of .78 miles per minute, how long before they both arrive at the station?
Answer:
1 minutes 9sec
Step-by-step explanation:
given data
Train
let the distance be x
distance covered by train= (15+x)miles
speed of train=65mile per minute
time t=?
we know that speed= distance/time
distance= speed*time
15+x=65t----------------------1
Roller coaster
distance=x miles
speed= 78miles per minutes
time t=?
we know that speed= distance/time
distance= speed*time
x=78t----------------------2
put x=78t in equation 1 we have
15+78t=65t
78t-65t+15=0
13t=-15
t=15/13
t=1.15====1miin 9sec
so it will take 1minutes 9sec
Determine the domain on which the following function is increasing.
Answer:
(-∞, -2]
Step-by-step explanation:
Domain of a function is defined by the x-values (Input values) and y-values define It's range.
From the graph of a parabola,
Graph shows the increase in the value from x = -∞ to x = -2 then the values are decreased from x = -2 to ∞.
Therefore, domain in which the function is increasing : (-∞ , -2]

charges an additional S4 for every mile.
Describe the cost of the delivery truck between 1 mile and 2 miles.
Answer:
the anser is 3 for one mile and 6 for two
Step-by-step explanation:
he charges 6 2 miles so have of six is 3 so one mile is 3$ and 2 is 6 they add the extra stuff to confuse you
Solve the Inequality algebraically.
4|7 – x|– 5 > 15
Answer:
Step 1: Add 5 to both sides.
4(|−x+7|)−5+5>15+5
4(|−x+7|)>20
Step 2: Divide both sides by 4.
4(|−x+7|)÷4 > 20÷4
|−x+7|>5
Step 3: Solve Absolute Value.
|−x+7|>5
We know either−x+7>5 or −x+7<−5
−x+7>5(Possibility 1)
−x+7−7>5−7(Subtract 7 from both sides)
−x>−2
−x -1 > -2-1(Divide both sides by -1)
x<2
−x+7<−5(Possibility 2)
−x+7−7<−5−7(Subtract 7 from both sides)
-x-1 > -2-1( Divide both sides by -1)
x<2
−x+7<−5(Possibility 2)
−x+7−7<−5−7(Subtract 7 from both sides)
−x-1 < −12-1 (Divide both sides by -1)
x>12

A kilobyte is 210 bytes and a megabyte is 220 bytes. How many kilobytes are in a megabyte?
Answer: 1.05 bytes (1.04761905)
Explanation: The operation to use when you need to find how much of something is in another is division. And since we're trying to find out how many kilobytes are in a megabyte, you'd need to divide 220 by 210. After doing so, you should get a quotient of 1.04761905. When a remainder is present, you can round it up. I chose to round up by the nearest hundredth. Therefore, there are 1.05 kilobytes in a megabyte.
I hope this helped!

what’s The definition of linear in Math
Answer: Linearity is the property of a mathematical relationship that can be graphically represented as a straight line. Linearity is closely related to proportionality. Examples in physics include the linear relationship of voltage and current in an electrical conductor, and the relationship of mass and weight.

To rent a bike, Max pays a flat rate of $5 plus an hourly rental fee. The graph shows the amount, C, in dollars, that Max pays based on the number of hours, t, that Max rents the bike. What is the rate of change in the cost to rent the bike with respect to the number of rental hours?
$5 per hour
$2.50 per hour
$2 per hour
$7.50 per hour
Answer:
C
Step-by-step explanation:
The rate of change in the cost to rent the bike with respect to the number of rental hours will be $2.5 per hour so option (B) will be correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
The rate of change is also called the slope of the function.
Since it is a linear function so slope will remain constant.
Slope = difference in ys coordinate/difference in xs coordinate
Slope = (30-5)/(10-0) = 2.5
Hence "The rate of change in the cost to rent the bike with respect to the number of rental hours will be $2.5 per hour".

What are the coordinates of the image of D'E'F'G' after a rotation of 90º counterclockwise? The coordinates of the pre-image DEFG are D(2,0) E(2,2) F(5,2) G(5,1)
Given:
The coordinates of the pre-image DEFG are D(2,0) E(2,2), F(5,2), G(5,1).
To find:
The coordinates of the image of D'E'F'G' after a rotation of 90º counterclockwise.
Solution:
If a figure is rotated 90º counterclockwise, then
[tex](x,y)\to (-y,x)[/tex]
Using this rule, we get
[tex]D(2,0)\to D'(0,2)[/tex]
[tex]E(2,2)\to E'(-2,2)[/tex]
[tex]F(5,2)\to F'(-2,5)[/tex]
[tex]G(5,1)\to G'(-1,5)[/tex]
Therefore, the coordinates of the image of D'E'F'G' after a rotation of 90º counterclockwise are D'(0,2), E'(-2,2), F'(-2,5) and G'(-1,5).
2. Determine the point and the slope given the equation y - 6 =1/2 (x + 3). m: point:
Equation in slope intercept form :
[tex]y = \frac{1}{2} x + 7\frac{1}{2} [/tex]
Slope = ½
Step-by-step explanation:
[tex]y - 6 = \frac{1}{2} (x + 3)[/tex]
Expand
[tex]y - 6 = \frac{1}{2} x + \frac{3}{2} [/tex]
Collect like terms and simplify
[tex]y = \frac{1}{2} x + \frac{3}{2} + 6[/tex]
[tex]y = \frac{1}{2} x + \frac{15}{2} [/tex]
Slope = ½

How do I solve x + 4 = -x - 4
Answer:
x = -4
Step-by-step explanation:
x + 4 = -x - 4
Get x on one side by adding x to both:
2x + 4 = -4
Subtract 4 from both sides:
2x = -8
Divide both sides by 2 to get x alone:
x = -4
