Llana [10]
The value of x is 83.
This is because all three angles of a triangle must sum up to 180 degrees. So 53+44=97 and 180-97=83.

In the expression below, a is an integer. 12^3+ax-20 if 3x+4 is a factor of the expession above, what is the value of a
SVEN [57.7K]

Our function is:

f(x)=12^3+ax-20

Now, if 3x+4 is a factor of f(x) then x=\frac{-4}{3} must satisfy the equation:

So, f(\frac{-4}{3} )=0

Putting x=\frac{-4}{3}

We get,

f(\frac{-4}{3} )=12^3+a(\frac{-4}{3} )-20=0

12^3+\frac{-4}{3} a-20=0

\frac{-4}{3} a=20-12^3=20-1708

a=-1708 \times \frac{-3}{4} =1281

So, the value of 'a' for the given expression is 1281.

Which matrix represents the system of equations shown below<br> Plz help..<br> See picture
Furkat [3]
Basically

just put the coeficinets of each variable in the apropriate row

example
ax+by=c and
dx+ey=f

would go in like this
\left[\begin{array}{ccc}a&b&|c\\d&e&|f\end{array}\right]

so
3x+1=1 and
0x-1y=5

\left[\begin{array}{ccc}3&1&|1\\0&-1&|5\end{array}\right]

D is answer
