10 1/8 inches. .............................
Answer:
y=1/2x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-3)/(4-2)
m=1/2
y-y1=m(x-x1)
y-3=1/2(x-2)
y=1/2x-2/2+3
y=1/2x-1+3
y=1/2x+2
Put in -4 for y
13x=4x+4(-4)
Subtract 4x from both sides
9x= -16
Divide both sides by 9
X=-16/9
Matrix A has 3 rows, 2 columns
Matrix B has 3 rows, 2 columns
The number of columns in matrix A (which is 2) does not match up with the number of rows in matrix B (which is 3).
So the matrix multiplication A*B is undefined. We cannot multiply the matrices.
The answer would be 10.5 in decimal form. In fraction form you could reduce 6 and 4 and make the six a 3 and make the four a 2. Then multiply it out. Which would be 3/1 multiplied by 7/2 = 21/2
