Hi there!
The question is asking us to simplify the expression (x² + 3x - 7)(2x - 5) and write the answer in standard form. Here is how you do that -
Original: (x² + 3x - 7)(2x - 5)
Break it apart - [(x² + 3x - 7)(2x)] + [(x² + 3x - 7)(-5)]
Simplify -
2x³ + 6x² - 14x - 5x² - 15x + 35
Now, combine like terms -
2x³ + x² - 29x + 35
Therefore, the answer to your query is 2x³ + x² - 29x + 35. Hope this helps!
Answer:
y = 128(4.926)^x
Step-by-step explanation:
Exponential function: y = ab^x
x = 0, y = 128
128 = ab^0
128 = a
--------------------
a = 128, y = 371,293, x = 5
371,293 = 128 x b^5
b^5 = ( 371,293 / 128 )
b = (fifth root) 5^√2900.7265625
b ≈ 4.926
----------------------------------------
y = 128(4.926)^x
I hope this helps!
Three tenths - one half is negative one fifth
Answer:
<h2>To accomplish his demands, he must accept 4 hours jobs or more than 4 hours jobs.</h2>
Step-by-step explanation:
We know that
Deepak charges $30 for each job plus $15 per hour, this means that the initial fixed fee is $30, and then he charges a variable fee of $15 per hour. This is expressed like
Where represents hours.
Now, if we only accepts jobs that pay at least $90, this means that the minimum fee is $90 and greater than $90. So, the whole expression is
Then, we solve for
Therefore, to accomplish his demands, he must accept 4 hours jobs or more than 4 hours jobs.
