Answer:
The original value of the car is $24,000
Step-by-step explanation:
Here, we want to calculate the original value of the car
Let the original value of the car be $x
Now, 4/5 of this value is $19,200
Mathematically, we have it that;
4/5 * x = 19,200
4x = 5 * 19,200
x = (5 * 19,200)/4
x = $24,000
x greater than, less than, or equal to 73 degrees?

Which of the following is a correct method to verify that two functions
are INVERSES of each other?
the graphs of the functions are a reflection across the line y = -x.
the graphs of the functions are a reflections across the y axis.
the graphs of the functions are a reflection across the line, y = x.
O The correct or complete answer is not in any of the choices.
Answer:
C) the graphs of the function are a reflection across the line, y = x
Step-by-step explanation:
Inverse functions have graphs that are reflections over the line y = x and thus have reversed ordered pairs.
HOPE THIS HELPS!!!! <33333

When that two functions are INVERSES of each other then
The graphs of the functions are a reflection across the line y = x
Option C
Given :
The two functions that are inverse to each other
When two functions are inverse to each other then
the domain of function f is the range of inverse function
The range of function f is the domain of inverse function
x values of function f = y values of inverse function
y values of function f = x values of inverse function
Hence we can say that the graph of function are reflection across y=x
The graphs of the functions are a reflection across the line y = x

A number raised to the power of 4 is equal to 625. Determine the number
Answer:
Step-by-step explanation:
[tex]n^4=625\\ \\ \sqrt[4]{n^4}=\sqrt[4]{625}\\ \\ n=5[/tex]
Answer:
5
Step-by-step explanation:
i started big the broke it down:
25*25=625 so that didnt work
so i went to 15
15*15=225*15=3375 and that also didnt work
so i went to 5
5*5=25*5=125*5=625
−5x + y = −3
3x − 8y = 24
Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) 3x - 8y = 24 {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
- 5x + y =-3 ......1
3x -8y = 24.........2
eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3
-40 x +8 y =-24 ...........3
3 x - 8y = 24 ......... 2
·································
-37 x +0 = 0
··························
x =0
put x = 0 in equation 2
3 x -8 y =24
3×0 -8 y = 24
0 -8 y=24
-y =24÷8
-y =3
y = -3
ans ;
x = 0
y = -3

Anyone know the answer to this?
Answer:
hello again
Step-by-step explanation:
the radius of the circle is 6mm
for having the circumference we need diameter
for having diameter we should multiply in 2
so:
[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]
i hope this is the answer

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.

Very easy!! help!! urgent!! its on ratio
Answer:
A and B are correct
Step-by-step explanation:

1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct
3/4 ×1 is not 3 so D isn't correct

divide 24xy² by 6yz²
Answer:
4xy/z^2
Step-by-step explanation:
Here, we want to make a division
We have this as;
24xy^2/6yz^2
that will be
24/6 * x * y^2/y * 1/z^2
= 4 * x * y * 1/z^2 = 4xy/z^2
