Answer:
I think the error is that the variable x came before the whole number 2.
[tex]x^2+3x+18 = (x+3)(x+6)[/tex]
↝ The error here is that (x+3)(x+6) doesn't make 3x in the middle here.
↝ From (x+a)(x+b) = x²+bx+ax+ab = x²+(a+b)x+ab
Now we let a = 3 and b = 6
Let's check the answer.
Given a = 3 and b = 6 (From the polynomials given.)
(x+a)(x+b) = x²+(a+b)x+ab
(x+3)(x+6)=x²+(3+6)x+(3*6)
(x+3)(x+6)=x²+9x+18
As you can see that the error here is that (x+3)(x+6) doesn't make 3x in the middle of polynomial. Therefore the error here is only 3x as proven.

The value of a certain car after one year was $13,595. The value of the same car after 3 years was $11,095. Find the slope and explain what it means.
Answer:
-1250/1 or -1250
This tells us that the car depreciated in value by $1250 every year.
Step-by-step explanation:
11,095-13,595= -2500
This is the value that the car has depreciated over 2 years (from the first year to the third year)
Since we need to find the slope we divide this value by two.
That value would be -1250
Since the value is negative, we know the car has depreciated in value. We also now know that it depreciated in value by $1250 every year
Hope this helps!

4. Interpret the solution
Answer:
1) The variable is x
2) [tex]1.5x > 51[/tex] Solving the inequality we get x>34
3) [tex]5b > 51[/tex], solving the inequality we get b>10.2

Simplify the expression. (−0.75x − 5) − (6.5x + 5.4)
Answer:
−7.25x−10.4
Step-by-step explanation:
Let's simplify step-by-step.
−0.75x−5−(6.5x+5.4)
Distribute the Negative Sign:
=−0.75x−5+−1(6.5x+5.4)
=−0.75x+−5+−1(6.5x)+(−1)(5.4)
=−0.75x+−5+−6.5x+−5.4
Combine Like Terms:
=−0.75x+−5+−6.5x+−5.4
=(−0.75x+−6.5x)+(−5+−5.4)
=−7.25x+−10.4

The most Julius can afford to pay per year in mortgage payments is $11,500,
and his credit score is currently 463. According to the following table for a
$150,000 mortgage, by how many points would he need to improve his credit
score in order to take a mortgage for $150,000?
Answer:
212 points
Step-by-step explanation:
He can only afford $11500 per year so divide that by 12, gets you 958 so he’s in the 675-699 range subtract 675- his current credit score to get the number of points he will need.

The table contains data on the number of people visiting a historical landmark over a period of one week. Which type of function best models the relationship between the day and the number of visitors?
A. A quadratic function with a positive value of a
B. A square root function
C. A linear function with a positive slope
D. A quadratic function with a negative value of a
Hence , it is to be quadratic function where a has to be less than zero.
Given that ,
The table contains data on the number of people visiting a historical landmark over a period of one week.
We have to find,
The relationship between the day and the number of visitors.
According to the question,
[tex]y = a\sqrt{x} + b[/tex]
And where x = no. of days = 1
y = no. of visitors = 45
45 = a [tex]\sqrt{1}[/tex] + b
45 = a + b
And When x = 2 and y = 86
86 = [tex]a\sqrt{2} + b[/tex]
Solving the equation for the values of a and b.
From equation 1
45 - a = b
Put the value of b in equation 2
86 = [tex]a\sqrt{2}[/tex] + 45 - a
86 - 45 = [tex]a \sqrt{2} - a[/tex]
41 = a ([tex]\sqrt{2} - 1[/tex] )
[tex]a = \frac{41}{\sqrt{2} - 1 }\\\\a = \frac{41}{0.41}[/tex]
a = 100
Put the value of a = 100
45 = 100 + b
45 - 100 = b
b = -55
The required equation is y = 100[tex]\sqrt{x}[/tex] -55.
When x = 4
[tex]y = 100\sqrt{2} - 55\\\\ y = 100 ( 1.4 ) - 55\\\\y = 140 - 55\\\\y = 85[/tex]
And when x = 5
[tex]y = 100\sqrt{5} - 55\\\\y = 223.5 - 55\\\\y = 168.60[/tex]
y = 168 ( approx )
Therefore, 168 ≠ 158
Since the function rises less and less in later stage , it can not be a first order function.
So, it is to be quadratic function where a has to be less than zero.

Answer:
D
Step-by-step explanation:
Its an abs value so you have to solve twice. Once for d - 3.5 < or equal to 1.5 which equals 5. You also have to solve for d - 3.5 > or equal to -1.5 which equals 2. So on the graph it has to be less than 5 and greater than 2 so you just connect the two and draw the line over the numbers in between the 2 and 5.

The total earning of commission on sales of 85, 000 will be:
[tex]3500+1050=4550[/tex]
Step-by-step explanation:
Total sales earning = 85,000As salesperson earns 5% commission the first 70,000.
[tex]\frac{5}{100}\:\times \:70\:000=3500[/tex]
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
85,000 - 70,000 = 15000So the 7% earning of salesperson will on 15000 will be:
[tex]\:\frac{7}{100}\:\times \:15\:000=1050[/tex]
Therefore, the total earning of commission on sales of 85, 000 will be:
