At age 6, he read six. That doubled would be 12 books. So at age 7, he read 12. 12 doubled is 24. At age 8, he read 24. That doubled would be 48. At age 9, he read 48. That double would be 96. So by age 10, he would have read 96 books.
Answer:
x = 15 and y = 10
Step-by-step explanation:
It is assumed that 'x' and 'y' are declared as '10' and '15' respectively. Then following the mystery(x, y) function which is pass 10 and 15 as parameter. Then we can follow the logic of the mystery function.
First, temp is assigned to one; that is temp = 10
Secondly, one is assigned to two; that is one = 15
Thirdly, two is assigned to temp; that is two = 10.
Since x and y is same as one and two; we say:
x = one = 15 and
y = two = 10.
The first time 6 reaches a ten is 30, which is times 5, so 5 erasers, and then easily 3 pencils, so the least amount is 5 erasers and 3 pencils :)
Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:
Putting into vertex form, remember that:
In this question:
, to put into this format:
We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:
So the correct answer is:
A. y = 7(x + 1)²-3
Answer:
x=1.33 repeating or 1 1/3
Step-by-step explanation:
You take 4 and distribute to everything in the parentheses.
You also do the same for the -4.
After you distribute, you should get: 4x+24=-8x+36+3x
Then you combine like terms (the two x's on the right side of the equation.
You should then get: 4x+24=-5x+36
Next, you subtract 24 from the positive 24, to cancel it out, and the 36 to get 12.
Then, add 5x to the negative 5x, to cancel it out, and to the 4x to get 9x.
Finally, you divide 12 by 9 to get 1.33 repeating or 1 1/3.
