True or False?

1 answer:

<span>"Every real number can be represented as a decimal, and every decimal represents a real number"

Every real number can be represented as a decimal --> True since non-terminating decimals are decimals too.

And every decimal represents a real number --> This is just the vice versa of the first statement. Hence true.

That's making the whole statement true. So both the statements are true.</span>

Make x the subject of the formula<br>y = mx + b

zubka84 [21]

Step-by-step explanation:

y=mx+c

Take c from both sides:

y-c = mx

Divide both sides by m:

(y-c) / m =x

Now swap sides to make it prettier:

x = (y-c) / m

3[x]+9 what is the graph?

ipn [44]

So, you can do this one of two ways.

The first is knowing what the numbers in your equation represent:

For example: y=mx+b in this case "b" is 9. b is the y-value when x=0. So the first point on our graph is (0,9). Next we have to pick an xvalue to solve for another y-coordinate.

I chose x= -3. Plug x into the equation to get y.
y=3x+9
y=3(-3)+9
y=(-9)+9
y=0

So, our second point is (-3,0).

connect the points with a ruler to graph the line.
