Answer:
y = - 
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= -
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = - x + 6 ← equation of line
Answer:
Step-by-step explanation:
x²- y² = (x+y) (x-y)
x² + xy = x(x+y)
x² + 2xy + y² = (x+y) (x+y)
It should be 25 or 20 because the way the problem is set up you should already have your answer of 2020
Answer:
There are a total of 70 cows in the herd.
Step-by-step explanation:
Represent the total number of cows by c. Then 0.20c = 14, and
c = 14/0.20 = 70.
There are a total of 70 cows in the herd.
A, b, e, f, all these contain an n to the 1st power
