Step-by-step explanation:
Answer:
2/7x + 8/7
Step-by-step explanation:
f(x) = -4 + 7/2x
y = -4+7/2x
Exchange x and y
x = -4 +7/2y
Solve for y
Add 4 to each side
x+4 = -4+4 +7/2y
x+4 = 7/2y
Multiply each side by 2/7
2/7(x+4) = 2/7 * 7/2y
2/7(x+4) = y
2/7x + 8/7
The quantity of product that would result in the same profit is 1 thousand. Option A
<h3>How to determine the function</h3>
Given the polynomial function as;
P(t) = –2t³ + 8t² + 2t
Where;
- P(t) is the company's profit = $8 million
- t is the number of skincare profit
Let's equate the values
–2t³ + 8t² + 2t = 8
–2t³ + 8t² + 2t - 8 = 0
Factorize the expression
(-2t³ + 8t²) + ( 2t -8) = 0
- t² ( 2t - 8) + (2t -8) = 0
We take the similar factor
2t - 8 = 0
2t = 8
t = 8/2
t = 4
But we have that the company produced 4 thousand products for $8 million profit, so we have
= 4/ 4
= 1 thousand
Thus, the quantity of product that would result in the same profit is 1 thousand. Option A

The answer for your question is 19/50
Answer:
The charge for shovelling snow for 6 hour is 72 hours
Step-by-step explanation:
Given as :
The charge for shovelling snow for 2
hours is $30
Let The charge for shovelling snow for 6 hours = $ x
Now, Applying unitary method
∵ The charge for shovelling snow for 2
hours = $30
or, The charge for shovelling snow for
hour = $30
So, The charge for shovelling snow for 1 hour =
hour
∴ The charge for shovelling snow for 6 hour =
× 6 hours
I.e The charge for shovelling snow for 6 hour =
hours
= 72 hours
Hence The charge for shovelling snow for 6 hour is 72 hours Answer
