Answer:
Y = (x + 1)^2 - 4
where is
look the Diagram when the line arrow cross to x line got -4 it's mean left side is Negative and reach to y diagram within 1 on positive to below
so the right answer is = Y = (x+1)^2 - 4
Answer:
Donuts(b) = 12*b
Step-by-step explanation:
Notice that the question is:
What's an expression to model the number of donuts in b boxes?
We know that we are talking of boxes of a dozen donuts.
We know that in one dozen, we have 12 donuts.
Then if we have b boxes, and in each box we have 12 donuts, we will have a total of b times 12 donuts, the expression is:
Donuts(b) = 12*b
There is a lot of information here that we did not use (like the cost of cardboard and donuts), and that may be there just to distract us, the important thing to do here is:
See what is the thing we want to find (in this case, the number of donuts in b boxes)
Find the relevant information to solve this. (ignore the irrelevant information)
Solve the question.
Answer:875
Step-by-step explanation:
Answer:
y = 5/3 x + 4
Step-by-step explanation:
To find the inverse, interchange the x and y variables and solve for y. (that might sound a bit confusing, but don't worry! :)
Our current function is f(x) = 3/5 (x-4). Let's make f(x) = y, so the function is y = 3/5 (x - 4).
Now, switch the x and y variables. x = 3/5 (y - 4).
Now, just solve for y!
x = 3/5 y - 12/5
5x = 3y - 12
5x + 12 = 3y
3y = 5x + 12
y = 5/3 x + 4
hope this helps! <3
