Answer:

y=-2x+4

Step-by-step explanation:

The gradient = change in y / change in x

When the x value increases by 1, the y value decreases by 2 so -2 / 1 = -2

The y intercept is 4, so it is +4

Calculate the kinetic energy of a boy of mass 65kg running with average speed of 20m/s (3mks)
lesya692 [45]
<h3>Answer:  13000 joules</h3>

This is equivalent to 13 kilojoules.

=======================================================

Work Shown:

m = 65 kg = mass

v = 20 m/s = velocity

KE = kinetic energy

KE = (1/2)*m*v^2

KE = (1/2)*65*(20)^2

KE = 13000 joules

This can be written as 13 kilojoules since "kilo" means "1 thousand"

The abbreviation of the unit "joules" is the letter J.

How do you determine what could represent a function in algebra
n200080 [17]
Hi, here is my answer:
First, if you want to determine that's relation is function, you have to realize that your value of x(Domain) is not repeated.= so, it's a function
But...If your value of x (Domain) is repeated twice or more, so I can guaranteed that is totally NOT a function
