No! 2^-3 is not equal to -3^2
So u have to rearrange to find x.
First u multiply by - 2 to get rid of the fraction bit
This leaves u with - 46>/x-49
Now u have to get x on its own which means you have to get rid of - 49 and to do this the opposite of - 49 is +49, so you would ADD 49
This gives you 3>/x
And the number line which represents this is B.
The Coefficient is 2.
The Constant is 4.
The Variable is x.
Answer:
y = 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (1, 8 ) into the partial equation
8 = 3 + c ⇒ c = 8 - 3 = 5
y = 3x + 5 ← equation of line
