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!

feet. Write and solve an
inequality to find how many
bags of soil Trini needs.
2. Write the inequality:
5 times b greater than 51
3.
Solve the inequality
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
Step-by-step explanation:
1. Define the variable:
The variable is x
2) Trini needs more than 51 cubic feet of soil to top up his raised garden. Each bag of soil contains 1.5 cubic feet. Write and solve an inequality to find how many bags of soil Trini needs.

Answer:
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:
[tex]3500+1050=4550[/tex]
Fill in the chart below using the information for Credit Card Finance. Mike starts with $1299.99 and an APR of 18% and makes no new purchases. The minimum payment is always 7%.
Answer:
Step-by-step explanation:
Step one:
given data
P= $1299.99
r=18%= 0.18
minimum rate r= 7%
t=1year
say the account is on simple interest the maximum payment is when the APR is 18%
A=P(1+rt)
A= 1299.99(1+0.18*1)
A= 1299.99(1.18)
A=1533.9882
$1533.9882
The minimum amount is when APR ia 7%
A=P(1+rt)
A= 1299.99(1+0.07*1)
A= 1299.99(1.07)
A=1390.9893
$1390.9893

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 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.

please help me it’s urgent
Step-by-step explanation:
i hope i didnt answer too late i see that ot says 7 min remaining but oh well
the answer
equation: (7x-13)+(x+29)+(3x + 5) = 180 (the reason why i put = to 180 is because every triangle adds up to 180 degrees)
first of all add the numbers: 29-13+5 = 21--- then add variables: 7x+3x+x= 11x
you get ur equation as: 11x + 21 = 180--- 180-21=11x---159=11x--- 159/11=14 9/20
x = 14 9/20 permiter = 88.15 + 43.45 + 48.35 = 179.95

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.
