Jordan is paying off a car loan. The function that models how much he has left to pay on his loan, P, is P(m)=6000−300m, where m is the number of months since Jordan took out the loan. What was the original amount of the loan?
A.) $18,000
B.) $6,000
C.) $20
D.) $300
Answer: B.) $6,000
Step-by-step explanation:
The equation shows how much Jordan has to pay per month until he is finished paying the loan.
This is a linear equation in the form: y = mx + c
y is the amount left to be paid
m is the change per month which means it is the amount paid per month
x is the independent variable that is changed which means it is the no. of months
c is a constant figure which in this case would be the amount borrowed.
With c being the amount borrowed as it is the constant in the equation, c in the equation must be 6,000 as this is the only constant.
The original amount of loan must therefore be:
= $6,000

Which model shows two equal expressions when the value of x is 4?
Sorry if the picture is dark
Given that y varies directly with x, use the specified values to write a direct 1 point
variation equation that relates x and y. x = 24 y=-6*
Answer:
y = - [tex]\frac{1}{4}[/tex] x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 24, y = - 6
- 6 = 24k ( divide both sides by 24 )
[tex]\frac{-6}{24}[/tex] = k , that is
k = - [tex]\frac{1}{4}[/tex]
y = - [tex]\frac{1}{4}[/tex] x ← equation of variation
Explain how to solve the equation
b - 7 = 12
Answer:
add 7 on both sides. b-7+7=12+7 to eliminate 7. you get b=19. hope this helps.

B
x 0 1 2 3 4
y 3 2 6 3 11
C
x -3 -2 1 6 -2
y 1 2 3 4 -1
D
x -2 -1 0 0 1
y 4 4 4 -2 -2
Answer:
B
Step-by-step explanation:
if there is two or more of the same X's it can't be a function. however if there is 2 or more of the same Y's it can still be classified as a function
please help it due asap
Answer:
c.29
Step-by-step explanation:
Your equation is 3x+18+75=180
Then, you combine like numbers so 75+18 so your equation is now 3x+93=180
Next, you subtract the 93 and get 3x=87
Finally, divide 87 by 3 to get x=29!!
Hope this helps have a great day :)
please help thanks.

Answer:
I am very positive that the answer is A.
Step-by-step explanation:
I believe it is A, because if you look at each of the input numbers there, they are 12, which divided by 2 is 6. 18, which divided by 2 is 9. 20, which divided by 2 is 10. 22, which divided by 2 is 11. This problem is a division problem.

Answer:
Option 3
Step-by-step explanation:
the symbol your question is showing is "greater than or equal to"
when a line includes "or equal to", the circle will be filled in. also, since the symbol is going towards 5, it is considered a greater than symbol. so, you'd want to choose the option with a filled in circle and an arrow pointing to the right.
since option 3 has a filled in circle and has its arrow pointing towards the positive (or right) side of the line, it should be option 3.

Emily wants to cover her kitchen floor with ceramic tile. The diagram below shows the layout of her kitchen.
What is the area of her kitchen floor, in square feet, that will be covered with ceramic tile?
411 ft2
381 ft2
255 ft2
567 ft2
Answer:
381 ft
Step-by-step explanation:
first get the area of the kitchen
22 x 18= 396 ft
now get the area of the island which is 3x 5= 15 ft
to know how much she would need to cover (not including the island), subtract 396 to 15
that would be 381 ft
Find the gradient of each of these functions at the point indicated.
a) y = x^2 at (3,9)
b) y = - 4x^3 at (1,-4)
c) y = 2x^4 at (-1,2)
d) y = 6x at (2, 12)
Answer:
Remember that the gradient is equivalent o the derivative evaluated in one point.
And remember that if we have a function like:
f(x) a*x^n
The derivative is:
f'(x) = n*a*x^(n - 1)
Then knowing this, let's start:
a) y = x^2
the derivative is:
y' = 2*x
And we want to evaluate this in the point (3, 9), then we just need to replace x by 3.
y'(3) = 2*3 = 6
The gradient of y = x^2 at (3, 9) is 6.
b) y = -4*x^3
The derivative is:
y' = 3*(-4*x^2) = -12*x^2
And we want to evaluate this on (1, -4), then we need to replace x by 1.
y'(1) = -12*1^2 = -12
The gradient of y = -4*x^3 at (1, -4) is -12.
c) y = 2*x^4
The derivative is:
y' = 4*2*(x^3) = 8*x^3
And we want to evaluate this on (-1, 2), then we need to replace x by -1.
y'(-1) = 8*(-1)^3 = -8
The gradient of y = 2*x^4 at the point (-1, 2) is -8
d) y = 6*x
The derivative is:
y' = 6
We can see that here we do not have any dependence on x, so the gradient will be the same for all values of x, this means that the gradient at the point (2, 12) is 6.
