Slope Intercept Form:<br> put the equation in slope intercept form.<br> 14x = 6y - 12
Pavlova-9 [17]

Answer:

y = 7/2x + 2

Step-by-step explanation:

To put the equation in slope intercept form [ y = mx + b ], we need to solve for y.

14x = 6y - 12

~Subtract 6y to both sides

14x - 6y = -12

~Subtract 14x to both sides

-6y = -12 - 14x

~Divide -6 to everything

y = 2 + 7/3x

~Reorder

y = 7/2x + 2

Best of Luck!

Give an example of where you would use either the Commutative or Associative Property of Addition in a real world situation.
umka2103 [35]

So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).

So (paper rock) scissors= paper scissors = scissors,

But paper (rock scissors)= paper rock = paper.

This is a good example because it shows that associativity matters even outside of math.

A train ticket was £4.50. The price then increased by 3%. What price is the train ticket now
mihalych1998 [28]

0.14 pounds (rounded; 0.135 unrounded); To calculate the % of something, divide it by 100 and multiply the result by the percentage you want to find.

0.0450 (=1%)

0.0450 x 3 = 0.135
