Always try to simplify prior graphing. However you have to mention where the function is continued or discontinued.
We notice that the numerator is a quadratic equation. Is roots are :
x = -2 and x" = 10
Then the numerator could be written (x+2)(x+10) and the function:
y= (x+2)(x+10)/(x+2). Prior to simplifying, you should notice that this function is discontinued for x = -2 (doesn't exist), so the domain is all x# -2.
Now you simplify and you will get:
y = (x-10) , which is a linear function, but cannot be at x = -2
Since 7 is greater than 5, the 9 gets rounded. It would be 12.0.
Answer:
3/40
Step-by-step explanation:
Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1/8 of the dessert and Walter ate 4/5 of the dessert, what fraction of the dessert was left over?
Let the total dessert be represented as = 1
The fraction of the dessert left over =
1 - (4/5 + 1/8)
Lowest Common Denominator = 40
1 - (4 × 8 + 1 × 5/40)
1 - (32 + 5/40)
1 - 37/40
Lowest Common Denominator = 40
40 × 1 - 37 × 1/40
40 - 37/40
= 3/40
Therefore, the fraction of dessert that is left over = 3/40
There are an infinite number of possibilities.
Here's one:
6x + 107 = -77x - 59
