Answer: x∈∅ (there is no decision).
Step-by-step explanation:
STEP-BY-STEP SOLUTION:
Let original price = x
New price with 10% discount from the original price = $50
( 100% - 10% )x = 50
90% of x = 50
x = ( 50 / 90% ) × 100%
x = $55.55 reciprocal
x = $55.55 ( to the nearest nickel )
The distributive property: a(b +/- c) = ab +/- ac
987 · 6 = 6 · 987 = 6 · (100 - 13) = 6 · 1000 - 6 · 13 = 6000 - 78 = 5922
The solution is
Step-by-step explanation:
The system of linear equation is
and
Using substitution method, let us substitute in the equation
Multiplying the term by , we get,
Subtracting both sides by ,
Simplifying, we get,
Now, substitute in
Thus, the solution is
Answer:
h(t) = 12 inches + (1 inch/week)t; continuous
Step-by-step explanation:
This situation can be described with a linear function. The initial value of the plant height is 12 inches, and the weekly growth is 1 inch/week.
Thus, if h(t) represents the plant height at the end of the t-th week,
h(t) = 12 inches + (1 inch/week)t
The slope is 1 inch/week, and is continuous, since plan growth is continuous.
