- Round:
3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like:
= x
Fourth, simplify
to
/ Your problem should look like:
= x
Fifth, switch sides. / Your problem should look like: x =
Answer as fraction:
Answer as decimal: -3.5
Answer:
A and D
Step-by-step explanation:
Moving the line left would be moving it onto the y - axis
Therefore the solution would be any point that starts with 0
So (0, 1), (0, 2), (0, -9), etc.

First, you'd work out the centre value
It would be the opposite value to what is in the brackets
Thus, the centre value is (2, -4)
Plot this value on a graph
In order to find the radius, you must square root the 25
Thus, the radius would be 5
Plot some points with a radius of 5 from the centre and then draw the circle
Have A Nice Day ❤
