Answer:
I gotchu <333
Step-by-step explanation:
A: y = 0.50x + 5
(y= total amount of money)
(+5 = birthday money)
B: (25) = 0.50x+5
-5 -5
--------------------------------
20 = 0.50x gilberto needs to get 40 correct answers
(divided) / 0.50 /0.50
-------------------------------------
40 = x
C:
y= 0.50 (12) + 5 gilberto will recieve 11 dollars !
y = 6+ 5
y = 11
If you are talking about the binomial being expanded then it would be:
8x^3 + 12x^2y + 6xy^2 + y^3
The y in the second term is not part of the exponent
And since you are raising the binomial to the third, you would be using the third row of Pascal's triangle.
Hope this helped!
Answer: Slope=1
You can find slope by using the 'rise over run' method. Count the number of units along the x axis, and up the y axis. As I can see, I think it is labeled as 4,4. So put the numbers into y/x (4/4) and then simplify as needed. In this case (If I can see correctly) then the slope is 1.
Answer:
Price of Caleb's groceries before tax = $64
