d = 4n-2 solve for n
The value of the equation d = 4n - 2 for n is (d + 2) ÷ 4.
Given data, d = 4n - 2
For finding the value of n first add 2 to both the side,
d + 2 = 4n - 2 + 2
d + 2 = 4n
Now, divide 4 into both sides of the equation:
(d + 2) ÷ 4 = 4n ÷ 4
(d + 2) ÷ 4 = n
∴ The value of n after solving the equation d = 4n - 2 is (d + 2) ÷ 4.

Trey is driving to Philadelphia. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Trey has 49 miles
to his destination after 37 minutes of driving, and he has 37.8 miles to his destination after 51 minutes of driving. How many miles will he have to his
destination after 57 minutes of driving?
distance (in miles)
Driving time(in minutes)
As per the linear function, the destination after 57 minutes of driving is 1055 miles.
Linear function:
The linear equation is defined as an algebraic equation of the form
y = mx + b.
involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given,
Trey is driving to Philadelphia. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes).
Trey has 49 miles to his destination after 37 minutes of driving, and he has 37.8 miles to his destination after 51 minutes of driving.
Here we need to find his destination after 57 minutes of driving.
In this one, first we have to find the linear equation for the situation.
For that, we need the slope and the intercept.
So, here we consider the distance as y axis and the corresponding time as x axis. then we get the points as,
(x1. y1) => (37, 49)
(x2, y2) => (51,37.8)
Then the slope of the line is calculated as,
m = (37.8 - 49) / (51 - 37)
m = -11.2/14
Now, the intercept is calculated using the point (37,49) and the slope m = -11.2/14 is,
49 = -11.2/14(37) + b
686 = -414.4 + b
b = 1100.4
So, the linear equation of the function is
y = -11.2/14x + 1100.4
Here we need to find the distance when the time is 57 minutes,
For that, we have to apply the value of x as 57, to get the value of y,
Therefore,
y = -11.2/14 (57) + 1100.4
y = -45.6 + 1100.4
y = 1055
Therefore, the destination after 57 minutes of driving is 1055 miles.

Suppose the function f(x) = 3x+10 and g(x) = 17x+4, then the value of (f+g)(x) is 20x+14
The function is an expression the show the relationship between one variable and another variable. If one variable is dependent variable another variable will be independent variable. We can also says that the function shows the relationship between set of inputs and set of out puts
The function f(x) = 3x+10
g(x) = 17x+4
We have to find the value of (f+g)(x)
We know,
(f+g)(x) = f(x) + g(x)
Substitute the values in the equation
(f+g)(x) = 3x+10 + 17x+4
Add the like terms
(f+g)(x) = 20x+14

The line segment AB with endpoints (-10,0) and (6,8). The equation of the line segment is x-2y+10=0.
Given that,
The line segment AB with endpoints (-10,0) and (6,8).
We have to find the equation of the line segment.
The equation of the line formula is y-y₁=m(x-x₁).

The equals sign is used in mathematical formulas to show that two expressions are equal. In contrast to English, where an equation is defined as any well-formed formula that consists of two expressions joined by the equals sign, French defines an equation as containing one or more variables. The first stage in resolving a variable equation is determining the values of the variables that lead to equality.
Here, 4x-1 =27

Safara wants to rent a bicycle the graph shows the cost for renting a bicycle for different lengths of time. What is the slope of the line?
The slope of the line will be equal to 30.
Slope of a line may be defined as the steepness of a curve. Slope of line can be positive, negative or zero. Slope of a line is used to determine the equation of the line which is given as y = mx + b where m is the slope, b is y intercept and x and y are independent and dependent variables respectively. The slope of a line on points (x₁, y₁) and (x₂, y₂) is given by the formula, m = y₂ - y₁/x₂ - x₁.
According to the question the value of points is (x₁, y₁) = (0, 0) and (x₂, y₂) = (2, 60).
Now, the slope can be calculated as
m = (60 - 0)/(2 - 0)
=> m = 60/2
=> m = 30 which is the required slope.
