The rearranged expression will be equal to y = (-5/4)x + 2.

<h3>What is an expression?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

<h3 />

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be rearranged as below:-

−5x−4y=−8

Solve the above expression for the value of y and the x variable will become independent.

−5x−4y=−8

Take -5x to the right side of the equation.

-4y = 5x - 8

Divide the equation by -4.

y = ( -5 / 4 )x + 2

Therefore, the rearranged expression will be equal to y = (-5/4)x + 2.

The cost of an uber ride, y, based on miles, x is represented by y = 2/3x + 4. How much does a 21-mile ride cost ?
dangina [55]

Answer:

Step-by-step explanation:

Let the cost of the Uber ride be represented by y in dollars.

Let the number of miles that the Uber rides be represented by x.

The equation relating x and y is expressed as

y = 2/3x + 4.

This is a slope intercept form equation. The slope is 2/3 and it represents the cost per mile.

The cost of a 21 mile ride will be

Substituting x = 21 into the given equation, it becomes

y = 2/3 × 21 + 4 = 14 + 4 = 18

The 21 mile ride costs $18

Part B) The $46 ride will cost

Substituting y = 46 into the given equation, it becomes

46 = 2x/3 + 4 =

46 - 4 = 2x/3

42 = 2x/3

2x = 42 × 3 = 126

x = 126/2 = 63

The $46 ride will be 63 miles

A tutor work with 3 students. The oldest student is 6 years oldder then the middle student, and the youngest student is 3 years
Dennis_Churaev [7]

Answer:

9 years old.

Step-by-step explanation:

Since the ages of all of these students are being represented in relation to the middle student's age then we can create formulas for each student and then apply them to the formula for the sum of their ages and solve for the middle child's age (M) like so... (oldest child's age is represented by variable O and youngest child's age is represented by variable Y)

O = M + 6

Y = M - 3

30 = (M+6) + M + (M-3)  ... combine like terms

30 = 3M + 3  ... subtract 3 from both sides

27 = 3M  ... divide both sides by 3

9 = M

Now we know that the middle child is 9 years old.

City Community College plans to increase its enrollment capacity to keep up with an increasing number of student applicants. The
aivan3 [116]
The given above may be modeled by the arithmetic sequence with initial value (I) 2200 and common difference (d) of 70. The number of applicants every year can be written by the equation,
                          at = a1 + (n - 1) x d
From the given above, n is equal to 4. This corresponds to the term which is 3 years from now. 
                           at = 2200 + (4 - 1) x 70 = 2410
Thus, the enrollment capacity would be 2410 students.
