The general form of the linear equation is,
      y = mx + b

where y is the dependent variable, m is the slope, x is the independent variable, and b is the y-intercept. 

Substituting the known values,

1. y = 2.6x

where y is the total cost and x is the number of gallons purchased.

2. y = 1.6x + 2

where y is the total weight of the bucket and the golf balls and x is the number of golf balls inside the bucket. 

3. P = 2x - (110/150)(x)

Simplifying,

   P = 19x/15

where P is the profit and x is the number of pounds of tomatoes brought to the market

4. y = 40x + 80

where y is the total number of enrolled students and x is the number of years

5. y = mx + b

where y is the total number of charge, m is the cost per person, x is the total number of persons and b is the flat fee

What is the slope of a line perpendicular to y = -7/4x?
dexar [7]
A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.

Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7

6x - 2y = 5
laiz [17]

Answer:

The given system has NO SOLUTION.

Step-by-step explanation:

Here, the given system of equation is:

6 x -  2 y = 5     .......... (1)

3 x  - y = 10          .... (2)

Multiply equation 2 with (-2), we get:

3 x  - y = 10     ( x -2)

⇒  - 6 x + 2 y = - 20

Now, ADD this to equation (1) , we get:

6 x - 2 y  - 6 x + 2 y  = 5 - 20

or, 0 = - 15

WHICH IS NOT POSSIBLE as 0 ≠ -15

Hence, the given system has NO SOLUTION.

Determine which consecutive integers do not have real zeros between them.
Alisiya [41]
The answer is option c (-1,0)
 Solving the equation you get that the zeros of this are approximately
 x ≈ -2.8019
 x ≈ -1.4450
 x ≈ 0.24698
 Then the function has three real roots, but none of them is within the range (-1,0)
 Below is a graph of the function.
