Answer:
y =10
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given
m = 0 and (x0, y0) = (4, 10)
On substituting;
y - 10 = 0(x-4)
y - 10 = 0
y = 0+10
y = 10
Hence the required equation of the line is y =10
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
In this problem we have
For
-----> 
so
Find the value of k

substitute the value of x and f(x)


therefore
the equation is equal to

For
-------> substitute in the equation and find the value of f(x)

Answer:
800
Step-by-step explanation:
i dont know how to explain. i just did the math. hope this helps.
it wouldnt be 600 because thats 1/2 of 1200 not 2/3.
Answer:
20 X 6
Step-by-step explanation:
20 X 6 = 120 I'm not smart but this is pretty easy
Answer:
x=16, y=-4
Step-by-step explanation:
-1(x-y=12)
x+7y=-20
-x+y=-12
x+7y=-20
8y=-32
y=-4
x-4=12
x=16
