Answer:
Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.
Properties of exponents are when you multiply, add, subtract, or divide exponents.

Answer: $480
Explanation: First, change the percentage to a decimal by dividing by 100. 40/100 = .4
Then multiply .4 by the cost, $1200. .4*1200 = $480
Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is 
, then m=. Since the y-intercept is -3, b=-3.
Then, we can create the equation: y=x-3
Standard form is y=mx+b, where m is the slope and b is the y intercept, substitute to find y=3x+3.
Hope this helps!
Answer:
4x+3y=5
Step-by-step explanation:
Subtract
4
x
from both sides of the equation.
3y = 5− 4x
Divide each term by 3 and simplify.
y= −4x 3+53
Rewrite in slope-intercept form.
