Answer:
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y-y1 = m( x-x1)
y--8 = -6(x-2)
y+8 = -6(x-2)
Distribute the -6
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Answer:
q = (r - px) / x
or you could write it as q = (r/x) - p
Step-by-step explanation:
px + qx = r
qx = r - px
q = (r - px) / x
Could you show the given circle please?
Answer:
1. Re-writing an equation to remove all the variables.
Step-by-step explanation:
Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.
In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.
The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.
35-15=20 is correct. However, 43-26 does not equal 23, it equals 17.
