The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.

Direct variation is only noticeable at the beginning of the graph after that the function is linear.

I hope the answer helps.

Write a C program to compute Matrix Multiplication of two matrices. Use one dimensional array to store each matrix, where each row is stored after another. Hence, the size of the array will be a product of number of rows times number of columns of that matrix. Get number of row and column from user and use variable length array to initialize the size of the two matrices as well as the resultant matrix. Check whether the two matrices can be multiplied or not. Write a getMatrix() function to generate the array elements randomly. Write a printMatrix() function to print the 1D array elements in 2D Matrix format. Also, write another function product(), which multiplies the two matrices and stores in the resultant matrix. With SEED 5, the following output is generated.


Sample Output


Enter the rows and columns of Matrix A with space in between: 3 5


Enter the rows and columns of Matrix B with space in between: 5 4


Matrix A:


   8     6     4     1     6


   2     9     7     7     5


   1     3     1     1     2


Matrix B:


   9     5     4     5


   9     9     8     1


   4     4     3     5




   2     6     2     1


   4     5     2     4


Product AxB:


168   146   106    91


161   186   125    81


50    52    37    22


In conclusion, the answer is D; No, because they are not similar triangles.

How to write -2x + y = -3 in slope intercept form? Preferably with steps.
Montano1993 [528]

Answer:

y = 2x - 3

Step-by-step explanation:

Start by writing out the given equation.

-2x + y = -3

The goal is to isolate the variable y.

For this equation, all you need to do is add 2x to each side.

-2x + y + 2x = -3 + 2x

Therefore, the answer is y = 2x -3.

I don't know if you are are familiar with the equation y = mx + b, but here's a little refresher. m is the slope, or in this case 2. b is the y-intercept, or in this case -3.

The equation y = mx + b is slope intercept form, so if you know this, you should be able to write any equation in slope intercept form.

Hope this helps!
