Classify the system as independent, dependent, or inconsistent.
Anastasy [175]
1. 4x + 8y = 12....divide by 4
     x + 2y = 3
     2y = -x + 3
     y = -1/2x + 3/2...slope is -1/2, y int is 3/2
 
     x + 2y = -3
     2y = -x - 3
     y = -1/2x - 3/2...slope is -1/2 and y int is -3/2

when the slopes are the same, and the y int are different, then the lines are parallel and never intersect...so they have no solution and are inconsistent
=================
2. y = 2x - 1...slope is 2 and y int is -1
    y = -2x + 5 ...slope is -2 and y int is 5
when the slopes are different and the y int are different, then there is 1 solution making it independent
=================
3. 4x - 12y = 8...divide by 4
     x - 3y = 2
same as other equation meaning the equations are the same line...meaning they have infinite solutions making them dependent

One fifth of a number, decreased by 17 is 41 in algebraic expression
asambeis [7]

The correct algebraic expression is X ÷ 5 - 17 = 41

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

An algebraic expression is a term that refers to a way of representing mathematical operations in which letters and numbers are combined, related to signs of the operations such as:

  • Addition (+)
  • Subtraction (-)
  • Multiplication (×)
  • Division (÷)
  • Empowerment (x^{2})

According to the above, we can infer that the correct algebraic expression would be:

  • X ÷ 5 - 17 = 41

In this algebraic expression the letter X represents a number that we do not know and we must find.

egoroff_w [7]

Answer:

y=2.50x+4.00

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

m=\$2.50\ per\ hour

The y-intercept (value of y when the value of x is equal to zero) is equal to

b=\$4.00 ----> (fee charge)

substitute the values

y=2.50x+4.00
