Answer:

A. 3.0 m/s

Step-by-step explanation:

Based on the graph,

velocity = Area of the graph

(y : position and x : time)

Let y1 = 2m and y2 = 14m,

t1 = 0s and t2 = 4s

v = (14 - 2)m/(4-0)s

= 12m/4s

= 3.0 m/s

Answer:

A. 3.0 m/s

Step-by-step explanation:

Based on the graph,

velocity = Area of the graph

$v = \frac{y1 - y2}{x1 - x2}$

(y : position and x : time)

Let y1 = 2m and y2 = 14m,

t1 = 0s and t2 = 4s

v = (14 - 2)m/(4-0)s

= 12m/4s

= 3.0 m/s

(7,9) has a slope of 1. Write equation in slope intercept form

Nadya [2.5K]

Step-by-step explanation:

Here, slope of the line (m) = 1

Here, slope of the line (m) = 1And, the line passes through the point (7,9)

Equation of the line is given by 

y - y1 = m ( x - x1 )

y - 9 = 1( x - 7)

y - 9 = x -7

x -7+9-y = 0

x - y + 2 = 0 

 is the required equation of the line.

I need a answer asap Please!!

Answer:

The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship ⇒ last answer

Step-by-step explanation:

* Lets explain how to sole the problem

- Proportional relationship describes a simple relation between

two variables

- In direct proportion if one variable increases, then the other variable

increases and if one variable decreases, then the other variable

decreases

- In inverse proportion if one variable increases, then the other variable

decreases and if one variable decreases, then the other variable

increases

- The ratio between the two variables is always constant

- Ex: If x and y are in direct proportion, then x = ky, where k

is constant

If x and y in inverse proportion, then x = k/y, where k is constant

* Lets solve the problem

# Last table

∵ x = 3 and y = 6

∴ x/y = 3/6 = 1/2

∵ x = 5 and y = 10

∴ x/y = 5/10 = 1/2

∵ 1/2 is constant

∵ x/y = constant

∴ x and y are proportion

* The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship
