Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
Answer:
x intercept is (4,0)
The y intercept is (0,12).
Step-by-step explanation:
Graph the x intercept (4,0) and the y intercept (0,12) and connect them with a line.
_______________________________________________________
(Equation) 3x + y = 12
To find the x intercept, set y = 0.
3x + 0 = 12
3 • 3 = 123
x = 4
The x intercept is (4,0).
To find the y intercept, set x = 0.
3(0) + y = 12
0 + y = 12
y = 12
The y intercept is (0,12).
To graph this line using the intercepts, first graph the two points (4,0) and (0,12). Then connect the two points with a line.
The complete question in the attached figure
we know that
if AC=22
then AE=AC/2----------> 22/2----------> AE=11
so
2x-5=11----------> 2x=16---------> x=16/2--------> x=8
the answer is x=8
