The system has two solutions.
You can tell because the second equation is a quadratic and the first is a line, so the line passes through the quadratic twice.
Its going to be B, a+14
Collect like terms
13a^2-12a^2-a^2-17a+12a+6a+14
Solve
a^2 is cancelled out (13-12-1=0)
12a+6a=18a-17a=1a
Bring the 14
The answer is a+14
The answer is B. You have to multiply matrices in a certain way.
So the top left corner of the answer is calculated by multiplying the first row of F to the first column of D:
0 x 2 + 4 x 3 = 0 + 12 = 12
etc..etc...
Answer:
Step-by-step explanation:
The given system of linear equations is:
We have to solve the equations for the values of .
Let us use elimination method in which we eliminate one of the variables from the two variables.
For this, let us multiply the first equation by and second equation by
Now, the equations become:
Now, let us add (1) and (2):
Using the equation:
Putting value of :
So, the answer to the system of linear equations is:
Answer:
24
Step-by-step explanation:
⅕×⅚×3/7×21×16
⅙×9×16 (Cancelling 5 by 5 and 21 by 3)
⅙×144
