He is wrong.  we are only looking at the last number which is 4
if we tripple 4 or 4*3 we get 12 which ends in 2, not 9

An airport has two long term parking lots. the cost to park,y, in each lot for x days is shown in the tables
Licemer1 [7]

Answer:

y = 4x + 12 will be the other equation.

Step-by-step explanation:

Data given in the tables show a linear relation (has a common data).

To get the linear relation, we will choose the two points from table (1) .

Let the points are (1, 16) and (2, 20).

Slope of the line 'm' = \frac{\triangle{y}}{\triangle{x}}

m = \frac{20-16}{2-1}

m = \frac{4}{1}

m = 4

Equation of the line passing through (1, 16) having slope = 4

y - 16 = 4(x - 1)

y = 4(x - 1) + 16

y = 4x - 4 + 16

y = 4x + 12

Now we take second set of data,

We choose two points (1, 6) and (2, 12).

Slope 'm' = \frac{\triangle{y}}{\triangle{x}}

m = \frac{12-6}{2-1}

m = 6

Equation of the line passing through (1, 6) having slope = 6

y - 6 = 6(x - 1)

y = 6x - 6 + 6

y = 6x

Therefore, other equation of the system of equations will be,

y = 4x + 12

Someone please answer!
Yakvenalex [24]

Answer:

m = -2

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in values:

m = 54 - 58 / 2 - 0

m = -4 / 2

m = -2

Considering the least common multiple of the denominators, it is found that the result of the expression is given by:

\frac{9100}{138320}

<h3>How do we add fractions?</h3>

We place all the terms of the addition in "equivalent" fractions, with the same denominator, found from the last common multiple of all the denominators.

In this problem, the denominators are as follows: 28, 70, 130, 208, 304. Using a calculator, their lcm is of 138,320.

Considering equivalent fractions(the numerators are the division of the lcm by the previous denominator), the expression is:

\frac{4940}{138320} + \frac{1976}{138320} + \frac{1064}{138320} + \frac{665}{138320} + \frac{455}{138320} = \frac{4940 + 1976 + 1064 + 665 + 455}{138320} = \frac{9100}{138320}

The distance traveled by a falling object is modeled by the equation below, where s is the distance fallen, g is gravity, and t
iren [92.7K]

Answer:

meters per seconds squared

Step-by-step explanation:

seconds squared cancel out and you're leftvwith just meters when

meters/seconds squared is multiplied with the seconds squared in t^2

g means gravity and

gravity is 9.8 meters per second squared
