Answer:
When they finished, the number of potatoes had Christen peeled is 20 potatoes.
Step-by-step explanation:
Given:
Homer began peeling a pile of 44 potatoes at the rate of 3 potatoes per minute.
Four minutes later, Christen joined him and peeled at the rate of 5 potatoes per minute We have to find the number of potatoes Christen has peeled.
Step 1 of 1
Homer peels 3 potatoes a minute, so in the four minutes he works alone, he peels potatoes.
This leaves 44-12=32 potatoes for them to peel together.
Together, they peel 3+5=8 potatoes per minute, so they need
minutes
to peel the rest of the potatoes.
Christen peels 5 potatoes a minute for 4 minutes, so she peels potatoes.
So, when we have this scenario of 1/0 when you put in the limit value that means f(x) does not exist there. Either it goes to +∞ or -∞.
The negative AFTER x in the limit x--> 9- means we are only looking at x approaching 9 from the left side.
when
x=8.8 ; f(x) = 1/-0.2
x=8.9 ; f(x) = 1/-0.1
See that f(x) becomes a larger negative number the closer to x=9 we get. That means the function goes to -∞ when we approach x=9 from the left side.
Should be the last answer -∞ , 9
Here, I'll have a try:
This expression is the multiplication of a binomial and a trinomial.. The binomial has two terms, while the trinomial has three terms. Use the distributive property of multiplication,
Step 1, multiply every term of the trinomial with the first term of the binomial, then multiple every term of the trinomial with the second term of the binomial. Use parenthesis to separate each multiplication to avoid confusion.
step 3, simply every multiplication
step 4, add up like trms
The slope of the line is
First, you must find 2 points.
(-6,8) (-2,5)
Then, you must substitute the value of the points in.
Finally, simplify the fraction.
