Answer:
first we get y on one side by itself.
4x+5y=5
we'll move x to the other side.
4x-4x+5y=5-4x
simplify.
5y=5-4x
now we get rid of the coefficient on y.
5y/5=(5-4x)/5
simplify.
y=5/5-4x/5
y=1- 
The answer is 
Answer:
{x,y,z} = {-22/13,29/13,6/13}
Answer:
y = -
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 2) ← 2 points on the line
m =
=
= - 
The line crosses the y- axis at (0, 6) ⇒ c = 6
y = -
x + 6 ← equation of line
Answer:
3/4 lb
Step-by-step explanation:
Lightest: 3 3/4
Heaviest: 4 1/2 = 4 2/4
4 2/4 - 3 3/4 = 18/4 - 15/4 = 3/4
Answer:
C and D
Step-by-step explanation:
9% = 9/100 = 0.09 < 0.4
0.125 < 0.4
7.8 * 100 = 780 > 0.4
7/16 = 0.4375 > 0.4
