Answer:
4x^2 + 19x - 63
Step-by-step explanation:
3(x-3) = 3x - 9
x + 3x - 9 (x + 7)
(4x -9)(x + 7) = 4x(x) + 4x(7) - 9x - 9(7)
4x^2 + 19x - 63

9514 1404 393
Answer:
8
Step-by-step explanation:
F(-8) is found by locating x = -8 on the x-axis, then determining the y-coordinate the graph has at that point.
f(-8) = 8

Log10 (2x + 1) - logio(3x - 2) = 1
Answer: x=3/4
Step-by-step explanation:
To solve, first express the left side as one logarithm. To do so, apply the quotient rule which is log_bM/N=log_bM-log_bN .
log((2x+1)/(3x-2))=1
Then, express the equation to its equivalent exponential form to eliminate the logarithm.
Note that the exponential form of log_b M=a is M=b^a .
Since the base of the logarithm in the given equation is not written, it indicates that its base is 10.
So re-writing the equation, it becomes:
log_10((2x+1)/(3x-2))=1
And its exponential form is:
(2x+1)/(3x-2)=10^1
(2x+1)/(3x-2)=10
Now that the equation has no more logarithm, the next step is to remove the x in the denominator.
To do so, multiply both sides by 3x-2.
(3x-2)*(2x+1)/(3x-2)=10*(3x-2)
2x+1=30x-20
Next, combine like terms.
To combine 30x and 2x, bring them together on one side of the equation. So, move 2x to the right side by subtracting both sides by 2x.
2x-2x+1=30x-2x-20
1=28x-20
To combine 20 and 1, bring them together on the side opposite the term with x. So, add both sides by 20.
1+20=28x-20+20
21=28x
And, divide both sides by 28 to have x only at the right side.
21/28=(28x)/28
3/4=x
Hence, the solution to the given equation is x=3/4 .
9.) Paul makes $300 a day and works 20 days a month, but he is fined $20 every day he is late. How
many days can he be late if he wants to make at least $5,910?
Answer:
3 days
Step-by-step explanation:
20 day x 300 dollar ＝6000 dollars
6000 dollar - 5910 dollar ＝90 dollar
Can be fined 80 dollar because 20 is even number
So,days can be fined:
60 dollar divide 20 dollar ＝3 days

9 Find the sum of (x + 5), (-4x – 2), and (2x – 1).
Answer: -x + 2
Step-by-step explanation:
So I assume that the question would be set up like this if you are finding the sum of all 3 terms:
(x + 5) + (-4x - 2) + (2x - 1)
1) Take out parentheses
x + 5 - 4x - 2 + 2x - 1
2) Add like terms
For the x terms:
x - 4x = -3x
-3x + 2x = -x
For the other terms:
5 - 2 = 3
3 - 1 = 2
The sum of the terms is -x + 2

If 70% of college students say they have a job what is the probability that 3 randomly selected college students say they have a job?
Answer: 0.343
Step-by-step explanation:
Probability of college students that say they have a job = 70%
Number of randomly selected college students = 3
The probability that 3 randomly selected college students say they have a job will be:
= (70/100)³
= 0.7 × 0.7 × 0.7
= 0.343

max has 3 5/6 pounds of potting soil. She uses 2 3/8 pounds to fill a pot. how many pounds of potting soil does max have left?
Answer:
1 11/24 pounds left
Step-by-step explanation:
For this question, find the common denominators of the fraction to add them.
A common multiple of 6 and 8 is 24.
So, 5*4 = 20 6*4 = 24
3 20/24 of potting soil initially
Then, 3*3 = 9 8*3 = 24
2 9/24 used
To find how many pounds are left:
3 20/24 - 2 9/24 = 1 11/24
