Answer:
13/20 Hours
Step-by-step explanation:
you have to find a common denominator. (20) You do 4x5 and 5x4 both equal 20. Then you do 1x5=5 and 2x4=8 then 8+5=13 then you make your fraction which is 13/20.
Answer:
-6
Step-by-step explanation:
because the roots are the x values of where the function crosses the x axis

Answer:
Step-by-step explanation:
You should place a point on the graph at 4 for four hours of TV last week. And place a point at 8 for eight hours of TV this week.
It looks like you have number 1 correct.
For number 2, what is alike is the exponent of 2. To combine them, add them together. You can do this because they are like terms (aka have the same variable and exponent)
3-4-1= -2. The answer is -2x^2
For number 3, those are not like terms. They either do not have the same variable (x or y) or they do not have the same exponent (1 or 2)
Both the exponent and the variable have to be the same for it to be a like term.
The answer is -2 because 2 * -6 = -12 -12 + 10 = -2
