Step-by-step explanation:
We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.
Let x= Number of tiles
y=Area covered by Felicia's tile
The ratio of x and y remains constant.Therefore, it is direct proportion .
Equation of direction proportion is given by
Where
k=The value of ratio of x and y
x and y are variables
We have k=9
Substitute the values in the equation
Then, we get
This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.
Answer:
A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
Step-by-step explanation:
we have
Solve for x
Adds 7 both sides
Divide by -3 both sides
Remember that
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The solution is the interval (-9,∞)
therefore
A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
