The cost for a day at the amusement park as a function of the number of ride tickets purchased is y = 12 + 2.75x
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the function of the number of ride tickets purchasedThe given parameters are:
Admission rate to the amusement park = $12
Cost of each ticket = $2.75
Let the number of tickets be x, and the total cost be y
So, the function can be represented as
y = Admission rate to the amusement park + Cost of each ticket * x
This gives
y = 12 + 2.75 * x
Evaluate the product
y = 12 + 2.75x
Hence, the cost for a day at the amusement park as a function of the number of ride tickets purchased is y = 12 + 2.75x

simplify the following absolutevalue expression |29|
Please i need help desperately.
The minimum cost is $210.
Forgetting the situation for just a second, we can take a look atthe equation.
c(x)=x^2-40x+610
It is a parabola that opens upward and has a minimum value.
That minimum value will be the minimum cost of the taco stand.
The equation x=-b/2a gives you the axis of symmetry of theparabola. Basically, it goes right down the middle of the parabola,right through its minimum
In the equation c(x)=x^2-40x+610, a=1 and b=-40
x=-b/2a
x=-(-40/2(1)) = 20
So 20 tacos should be sold to achieve the minimum cost.
To find the cost, return to the original equation.
c(x)=x^2-40x+610
c(20)=(20)^2-40(20)+610 = 210
So the minimum cost is $210.
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

The minimum cost of the function is $210.
A function is defined as the representation of a set of variables known as the domain which are mapped onto another set of variables called the range.
The most common function is of the form y = f(x) , where x is the independent variable and y is the dependent variable and f(x) is the function.
The given function is of the form:
c(x) = x² - 40 x + 610
To find the maximum or minimum point of the function we find the second degree derivative of the function.
c'(x)=2x -40
Now we find the second degree derivative.
c"(x) = 2 > 0 so we know that c(x) is minimum at x for c'(x)=0.
Therefore c'(x) = 0
or , 2x-40 = 0
or , x = 20
Now the minimum value of the function is
c(20) = 20² - 40 (20) + 610
or, c(20) = 400 - 800 + 610
or, c(20) = 210
Hence the minimum value of the function is $210.

Write the equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point 7. y=-2x + 5; (3,-7)
Answer:
The equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point (3,-7) is y = -2/7x - 6.14
Step-by-step explanation:
It is given that the line that is parallel to the group in each equation and passes through the given point 7y= -2x + 5; (3,-7) and we need to write the equation in slope intercept form of the same line.
Now,
The slope of parallel lines is the same. By changing the equation to slope-intercept form, get the slope in the first line;
=> 7y= -2x + 5
=> y= -2/7x + 5/7
So, the slope = -2/7
Further,
Given the point and the knowledge that the second line would similarly have a slope of -2/7 and the point is (3, -7). With these numbers, we can construct an equation in the slope-intercept form and apply it to get the y-intercept;
=> y = mx + b
=> -7 = -2/7 × 3 + b
=> -7 + 2/7 × 3 = b
=> b = -6.14
Now, put the value of y-intercept back into the equation;
=> y = -2/7x - 6.14
Therefore, the equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point (3,-7) is y = -2/7x - 6.14
