A girl buys a monthly bus pass, which entitles her to unlimited bus travel, for $40 per month. Without the pass each bus ride costs $1.60. How many rides per month would she have to take so that the cost of the rides without the bus pass is equal to the total cost of the rides with the bus pass?
The number of rides at which the unlimited ride pass equals the cost of individual ride purchases is ?.
Answers
Answer: 25 Rides
Step-by-step explanation:
Forty (cost of pass per month) divided by 1.60 (Cost of rides) = 25 rides until the cost of the rides equals the price of the pass.

Step-by-step explanation:
The required simplified value of the given expression is 4.
Given that,
An expression is given, {[(12−36)÷(−12)]2−20}÷(−4 a simplified value of the expression is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Simplifying,
= {[(12−36)÷(−12)]2−20}÷(−4)
=[ [-24/-12]2-20] / - 4
=[4-20] / - 4
= -16/-4
= 4

Though we can divide this second equation by five and combine, let's multiply the first equation by five and subtract it from the second...
10d + 5n = 210

pick-m-up towing company charges 40$ to hook a car and 1.70 for each mile that it is towed. write an equation that represents the total cost y for x miles towed. find the y intercept, and interpret its meaning in the context of the situation
Answers
Using linear function concepts, it is found that:
The equation for the cost of x miles towed is: [tex]y = 1.7x + 40[/tex].The y-intercept is [tex]y = 40[/tex], which means that the flat fee is $40.A linear equation for a cost has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the fixed cost, also called flat fee.In this problem:
The y-intercept is the cost to hook a car, which is $40, thus [tex]b = 40[/tex] and the flat flee is $40.Cost of $1.70 per mile towed, thus the slope is [tex]m = 1.7[/tex].Then, the equation for the cost is given by:
[tex]y = 1.7x + 40[/tex]

The larger of two numbers is 5 more than the smaller. The smaller number plus the larger equals 100. Find the number.
Answers
Answer:
Smaller number-47.5
Larger number-52.5
Step-by-step explanation:
We will make the smaller number x. If the smaller number is x, then the larger number will be equal to x+5. We also know that when we add the two numbers, we get 100. We can make the equation
x+x+5=100
100-5=95
2x=95
95/2=47.5
x=47.5
The smaller number equals 47.5 and the larger number is 47.5+5 which equals 52.5

Determine the domain and range of the given function:
y = –x4 + 4
This is just a garden-variety polynomial. There are no denominators (so no division-by-zero problems) and no radicals (so no square-root-of-a-negative problems). There are no problems with a polynomial. There are no values that I can't plug in for x. When I have a polynomial, the answer for the domain is always:
the domain is "all x".
The range will vary from polynomial to polynomial, and they probably won't even ask, but when they do, I look at the picture:

The graph goes only as high as y = 4, but it will go as low as I like. Then:
The range is "all y ≤ 4".

If y = xy + x2 + 1, then when x=-1,
dy/dx
Answers
dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.
If y = xy + x² + 1, then when x=-1,
dy/dx = -1/2
What is Derivatives?The rate of change of a function with respect to a variable are called Derivatives.
Given that, y = xy + x² + 1
Put x = -1 we get,
y = -1y + (-1)² + 1
y = -y + 1 + 1
y = 1
Now Differentiating the given equation w.r.t x
dy/dx = xdy/dx + y + 2x
dy/dx - xdy/dx = y + 2x
dy/dx (1 - x) = y + 2x
dy/dx = (y + 2x)/(1 - x)
Put x = -1 and y = 1 we get
dy/dx = (1 + 2(-1))/(1 - (-1))
dy/dx = -1/2
Hence, y = xy + x² + 1, then when x=-1,
dy/dx = -1/2

D = -38t + 220
Rachel is driving a race car at a constant speed on a closed course. The formula shown above describes the remaining distance, D, measured in meters, that Rachel has to travel after t seconds. What is Rachel's speed in meters per second?
Answers
Answer: 38 meters per second
Step-by-step explanation:
Rachel's speed is 38 m/s.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
D = -38t + 220
So, t = 1
D = -38t + 220
D = -38(1) + 220
D = -38+ 200
D = 182 m
So, v = [tex](D_0 - D_1)[/tex] / t
v = ( 220- 182) /1
v = 38 m/s
Hence, Rachel's speed is 38 m/s.
