A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year. 1 Write an exponential function that models the value x of the car over y years. 2 To the nearest cent, what will be the value of the car after eight years?
Answers
the given P=15250
r=7.5/100=0.075
t=x
y = 15250*(1 - 0.075)^x
after 8 years we would have
x = 8
y = 15250*(1 - 0.075)^8
y = $8,173.42
Answer: after 8 years the value of the car would be $8,173.42
Nineteen more than a number is 33. What is the number? 33 n 19

Answers
Answer:
14
Step-by-step explanation:
33-19=14
Answer:
14; B
Step-by-step explanation:
You know that x + 19 = 33.
If you subtract 19 from both sides you get 14.
or you could think of it this way:
if you have 19 things and there is another person that has x amount, but all together you have 33 things/items. Then you have to subtract in order to figure out how many things the other person has.
And you can check your work by just adding 19 and 14 which will indeed give you 33.

Step-by-step explanation:
Counterclockwise Rotation About the Origin
Given the point (x,y), the counterclockwise rotation about the origin is the point (-y,x), i.e. the coordinates are switched and the y-coordinate is opposed.
The points of the quadrilateral are T(1,-2), S(5,-3), R(5,-4), U(2,-4). The rotated points are:
T'(2,1), S'(3,5), R'(4,5), U'(4,2).

Answer:
The inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
Step-by-step explanation:
Given the inequality
[tex]-3\:>\:4[/tex]-3 can not be greater than 4, so [tex]-3\:>\:4[/tex] is also incorrect.
Given the inequality
[tex]-2\:<\:-3[/tex]-2 can not be lesser than -3, so [tex]-2\:<\:-3[/tex] is also incorrect.
Given the inequality
[tex]-3\:<\:-6[/tex]-3 can not be lesser than -6, so [tex]-3\:<\:-6[/tex] is also incorrect.
Given the inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
are these Equivalent expressions 4(2 + 3) and 4(2) + 4(3)
Answers
Answer:
Yes, they are equivalent.
Step-by-step explanation:
To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.Apply the distributed property: 8 + 128 + 12 = 20For second expression:
4(2) = 4 × 2 = 84(3) = 4 × 3 = 12Put them together: 8 + 128 + 12 = 20Making a conclusion:
Because they both have the same answer, they are equivalent expressions.

Which of the following is a true statement?
1. CM = CD
2. 2(AB) = AM
3. 2(MB) = AB
4. 1/2 (AM) = AB
Answers
Answer:
3. 2(MB) = AB
Step-by-step explanation:
1. This is not true because CM is less than CD.
2. This is not true because 2(AB) is greater than AM.
3. This is true because AB = 2(MB) or 2(AM).
4. This is not true because 1/2(AM) is less than AB.
Let's put some values on number 3 to check if it's, indeed, true.
Let's say AB's distance is 50 meters, then AM and MB should be half of it; that is: AM/MB = 25 meters. Let's check:
2(MB) = AB
2(25) = 50
50 = 50

its suppose to be put into point slope form y=mx+b
Answers
Answer:
Slope-intercept is a specific form of linear equations. It has the following general structure. Drum roll ...
\Large y=\maroonC{m}x+\greenE{b}y=mx+by, equals, start color #ed5fa6, m, end color #ed5fa6, x, plus, start color #0d923f, b, end color #0d923f
Here, \maroonC{m}mstart color #ed5fa6, m, end color #ed5fa6 and \greenE{b}bstart color #0d923f, b, end color #0d923f can be any two real numbers. For example, these are linear equations in slope-intercept form:
y=2x+1y=2x+1y, equals, 2, x, plus, 1
y=-3x+2.7y=−3x+2.7y, equals, minus, 3, x, plus, 2, point, 7
y=10-100xy=10−100xy, equals, 10, minus, 100, x [But this equation has x in the last term!]
On the other hand, these linear equations are not in slope-intercept form:
2x+3y=52x+3y=52, x, plus, 3, y, equals, 5
y-3=2(x-1)y−3=2(x−1)y, minus, 3, equals, 2, left parenthesis, x, minus, 1, right parenthesis
x=4y-7x=4y−7x, equals, 4, y, minus, 7
Slope-intercept is the most prominent form of linear equations. Let's dig deeper to learn why this is so.

The point does the graph of the line y=2x−6 cross the y-axis will be (0, -6). Then the correct option is C.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given as,
y = 2x - 6
At the y-axis, the value of the variable 'x' becomes zero. Then we have
y = 2 (0) - 6
y = - 6
The point does the graph of the line y=2x−6 cross the y-axis will be (0, -6). Then the correct option is C.

will he have less than 10 pairs of shoes?
I need the inequality
Answers
Answer: w < 9
Step-by-step explanation:
Answer:
9 weeks
Step-by-step explanation:
Divide the total pairs of shoes by how many you lose in a week and it will give you about how many weeks it'll take to get rid of all of the shoes:
35 / 3 = 11.67
Knowing your multiplication table is key for this! You will know that the best answer for this is 9 (and not 8 or 10) because...
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
Which will give you less than 10 pairs:
35 - 27 = 8
