To solve this one-step equation you:
1. Substract 9 in both sides of the equation:
In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.
2. Divide both sides of the equation into 5:
Then, the answer that Sara should found for the equation is x=4
Answer:
A
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here g(x) = f(x) - 2 ← with c = - 2 < 0
Then g(x) is the graph of f(x) shifted down 2 units
Nope, but if you need help you can tell me what the questions are and I'll try solve them!
Answer:
(a) 75 minutes
(b) 50 minutes
(c) labeling speed = Number of books to label ÷ Time taken to finish labeling them
Step-by-step explanation:
Firstly, she has 750 books to label and she labels 10 books in a minute. Hence, the number of minutes it will take her will equal the number of books divided by the number of books labeled in a minute.
This will be 750/10 = 75 minutes
Secondly, we use the same approach here but the number of books she labeled in a minute is different. Hence we get 750/15 = 50 minutes.
Lastly, the relationship between her labeling speed and the number of minutes is shown as follows.
The speed has a unit of books/minute since it is a rate and this is equal to number of books labeled ÷ Time taken to label them
