-2(3a-b)=c , what would you do if you were trying to isolate b

IrinaK [193]

Answer:

$b=3a+\frac{c}{2}$

Step-by-step explanation:

First, distribute the -2 to the rest of the parenthesis, following PEMDAS.

$-2(3a-b)=c\\-6a+2b=c$

Then, add -6a to both sides.

$2b = 6a+c$

Now, you can divide both sides by 2 to isolate b.

$b=\frac{6a+c}{2}$

Divide to simplify.

$b=3a+\frac{c}{2}$

What is the equation of the graphed linear model? y = x + Scatter plot on a first quadrant coordinate grid. The horizontal axis

Rasek [7]

If you have line on the scatter plot that is drawn through the points (1,3) and (9,11) then we will first calculate the slope:
m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1
Then the interception with y-axis:
y=mx+b
3= 1*1 + b
3-1=b
b=2
The equation is:
y=x+2
