Answer:
46 cents, or $0.46
Step-by-step explanation:
Divide 2.76 by 6 to find the cost of one can.
2.76/6 = 0.46
So a can of soda costs 46 cents.
Transforming equation systems into matrix form is fairly simple:
each column represents a variable, and each line represents an equation.
So in the first column, the NUMBERS MULTIPLYING by the X variables are put, in the second one the ones multiplying by Y, etc. The constants go after the vertical line, the last column
so we have:
So in a matrix, it will be the one on the picture
Answer:
y=-2x+6
Step-by-step explanation:
So you know the perpendicular gradient is -2 so the equation so far is y=-2x+?
Find the midpoint of AB which is:
(3,0)
Using this, plug it into the equation you've formed:
0= -6 + ?
? = 6
So the equation of the perpendicular line is y=-2x+6
