Answer:
Yes, "y" varies directly with "x"
The constant of variation is:
Step-by-step explanation:
Constant variation equation has the following form:
Where "k" is the constant of variation.
You can notice in the table the when "x" increases, "y" increases and the ratio between them is always the same.
To find "k" you need to pick any a point from the table, subsitutte the coordinates into and solve for "k". Then:
PATHOGEN: in biology, a pathogen in the oldest and broadest sense, it is anything that can produce disease. A pathogen can also be referred to as an infectious agent, or a germ.
Answer: B
Step-by-step explanation:
first write t in terms of x
x = 7t - 3
7t = x+3
t = x/7 + 3/7
plug into y
y = 5t+1
y = 5x/7 + 15/7 + 7/7
y = 5x/7 + 22/7
so your answer is B
Answer:
$55.07 Answer C is closest
Step-by-step explanation:
The original price of the 2 sweaters was 2($45.89) = $91.78
To find the price at 40% off, multiply this $91.78 by
1.00 - 0.40, or 0.60:
0.60($91.78) = $55.07 Answer C is closest.
