Answer:
Step-by-step explanation:
First, you need to simplify step-by-step:
6x−24x+13
=6x+−24x+13
Now, you combine like terms:
=6x+−24x+13
=(6x+−24x)+(13)
=−18x+13
That's how you get your answer:
=−18x+13
Answer:
x = 20,000
p = $40
If the price increase by $1, the demand will decrease by 1000
Step-by-step explanation:
Given:
x = 160 - p
x = number of Robby costumes demanded in thousands
p = price in dollars.
a. How many costumes can be sold at a price of $140?
x = 160 - p
x = 160 - 140
= 20
x = 20,000
20 thousand costumes can be sold at a price of $140
b. What price should be charged if the demand is 120,000 Robby costumes?
x is in thousand
p is in dollars
x = 160 - p
x + p = 160
120 + p = 160
p = 160-120
= 40
p = $40
c. If the price increases by $1.00, by how much does the demand decrease?
x = 160 - p
= 160 - 141
= 19
x= 19,000
If the price increase by $1, the demand will decrease by 1000
W - y > h/p
h < (w - y)p
*All you have to do is subtract y from both sides and multiply both sides by p to get the answer, answer is in bold.
The height in meters of a lava rock that falls for 5 seconds will be 122.5 meters.
The missing function is y = 1/2 gt².
<h3>What is a function?</h3>
A function is a remark, tenet, or regulation that establishes a relationship between the two parameters.
The height of lava fountains spewed from volcanoes cannot be measured directly.
Instead, their height in meters can be found using the equation is given as
y = 1/2 gt²
where y represents the height, g is 9.8, and t represents the falling time of the lava rocks.
Then the equation will be
y = 1/2 × 9.8 × t²
y = 4.9t²
Then the height in meters of a lava rock that falls for 5 seconds will be
y = 4.9 x 5²
y = 122.5 meters
