You can make use of the slope-intercept form of a line which is:
y = mx + b
Substitute m and the coordinates of a point in the line to find b,
-2 = (2/5) (5) + b
b = -4
The equation is
y = (2/5) x - 4
In standard form:
(2/5)x - y = 4
2x - 5y = 4
Answer:
Step-by-step explanation:
The answer is 33cm.
width: x length: 6+x
x+x+6=72 ==>
2x+6=72 ==>
2x=72-6 ==>
2x=66 ==>
x=66/2 ==>
x=33.
width=33 33+6=39 >length
33+39=72>perimeter
Answer:
The answer is B

Answer:
Step-by-step explanation:
(x^3/x^4)^2
=(x^3×x^{-4})^2
=(x^{3-4})^2
=(x^{-1})^2
=1/x²
