An identity is an equation that is true for all real values in its domain.
An identity is an equation that is true for all real values in its range.
An identity is an equation that can be verified by substituting input values.
The correct answer is:
An identity is an equation that is true for all real numbers.
Explanation:
An identity is a mathematical statement that is always true. It does not matter what numbers you substitute in for the variables, the result will be the same.
its original area. If he reduces the width to
30 feet, what should the new length be?
Answer:
40 feet
Step-by-step explanation:
60x40=2400
2400/2=1200
1200/30=40

b. predict the daily sales of Fun Noodles if the price is $4.50
Answer: PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000
PART B:
For the price of 3.50 we have:
y = -1000 * (3.5) +9000
y = 5500
