15x-37=38 what is the answer to that i really really need it
Answers
+ 37 + 37
15x = 75
÷15 ÷15
x = 5
To check:
15x - 37 = 38
15(5) - 37 = 38
75 - 37 = 38
38 = 38
so your final answer is: x=5.
Hope this helps:)

First use the distributive property for the first two:
(2x^5+8x^4+6x^3+3x^4+12x^3+9^2+4x^3+16x^2+12x)(x+4)
And then combine like terms:
(2x^5+11x^4+22x^3+25x^2+12x)(x+4)
Continue use the distributive property:
(2x^6+11x^5+22x^4+25x^3+12x^2+8x^5+44x^4+88x^3+100x^2+48x)
Continue combine like terms:
(2x^6+19x^5+66x^4+113x^3+112x^2+48x)
And that is your final answer.

The value of n obtained from equation 2n+1=21 is 10.
Value of n to be determined in equation 2n+1=21.
What is arithmetic?
Statements execute as mathematical expressions. In arithmetic mathematics deals with various statements, progressions, sequences etc.
Here,
⇒2n+1=21
2n=21-1
2n=20
n=20/2
n=10
Thus, the value of n in equation 2n+1=21 is 10.

You are left with 2n=20
Then, divide 2 into 20, and you get 10
So, the value of n is 10

(x) 1 1 3 3
Output
(y) 4 2 12 6
Part A: Does the table represent y as a function of x? Justify your answer. (5 points)
Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below:
f(x) = 20 + 10x
What is the value of f(120), and what does f(120) represent? (5 points
Answers
Answer with explanation:
Part A:
- A relation is said to be a function where each input has only a single output.
We usually take the input variable as 'x' and the output variable as 'y'.
In the given table, we can see that 1 is the input value corresponding to 4 and 2 both.
i.e. one input value corresponds to two different output values that contradicts the definition of the function.
Thus the given table doesn't represent any function.
Part B: Given : The total cost f(x), in dollars, for renting a paddle-boat for x hours is shown below:
At x= 120 ,
It represents that the total cost for renting a paddle-boat for 120 hours is $1220.
The table doesn't represent y as a function of x.
Why? One reason is that 1 or 3 is the first element in more than one ordered pair.
Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220
f(120) represents cost of boating for 120 hours.
the coordinates of its image?
Answers
The coordinates of the image of point (2 , -4) after reflection across
the x-axis is (2 , 4)
Step-by-step explanation:
Let us revise the reflection of a point
1. If point (x , y) reflected across the x-axis, then its image is (x , -y)
2. If point (x , y) reflected across the y-axis, then its image is (-x , y)
3. If point (x , y) reflected across the line y = x, then its image is (y , x)
4. If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point (2, -4) is reflected across the x-axis
∵ Point (x , y) reflected across the x-axis, then its image is (x , -y)
- Chang the sign of the y-coordinate of the point to find its image
∵ The y-coordinate of the point is -4
∴ The y-coordinate of the image is 4
∴ The image of the point (2 , -4) is (2 , 4) after reflection across the
x-axis
The coordinates of the image of point (2 , -4) after reflection across
the x-axis is (2 , 4)
