Answer:
1
Step-by-step explanation:

Answer:
multiply 5 x 4 = 20
multiply the dimensions of the lighter square
after all the multiplying you subtract your answers and you should get the VERY final answer
*don't add because it's area; just multiply
Answer:
x = -1/5y + 3/5
Step-by-step explanation:
y = 3 - 5x
Subtract 3 from both sides;
y - 3 = -5x
Divide both sides by -5
-1/5y + 3/5 = x
Answer:
see explanation
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 )
Rearrange x + 5y = 10 into this form
Subtract x from both sides
5y = - x + 10 ( divide all terms by 5 )
y = -
x +2 ← in slope- intercept form
with slope m = - 
• Parallel lines have equal slopes, hence
y = -
x + c ← is the partial equation of the parallel line
To find c substitute (1, 3) into the partial equation
3 = -
+ c ⇒ c = 
y = -
x +
← equation of parallel line
