#1: p=0
#2:all real numbers
#3: a= -2

First one is -30p = 0 because distribute 5 to get 60 - 15p and its the same on both sides except for one sign. 
second has infinite solutions because distributing gives 3y - 6 = 6y - 6 - 3y. Combine like terms to get 3y - 6 = 3y - 6. When the equation has a number equaling another number there are infinite solutions. 
Third one is a = -2 because if you add 4a to both sides you get 7a + 21 = 7. Then subtract 21 from both sides to get 7a = -14. then divide by 2 to get the answer.

F(x) = 9 − x2, x < 3 x − 3, x ≥ 3

The table of the function is;

x      f(x)

1       8

2      5

3      0

4      1

5      2

<h3>What are the output values of the x-variables?</h3>

Given the piecewise functions;

           9 - x²,      x < 3

f(x) = {

          x - 3,       x ≥ 3  

For x = 1, since 1 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(1) = 9 - (1)²

f(1) = 9 - 1

f(1) = 8

Hence, we have a point ( 1,8 )

For x = 2, since 2 is less than 3, we use the piece of the function under x<3

f(x) = 9 - x²

f(2) = 9 - (2)²

f(2) = 9 - 4

f(2) = 5

Hence, we have a point ( 2,5 )

For x = 3, since 3 is greater than or equal to 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(3) =  (3) - 3

f(3) = 3 - 3

f(3) = 0

Hence, we have a point ( 3,0 )

For x = 4, since 4 is greater than 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(4) =  (4) - 3

f(4) = 4 - 3

f(4) = 1

Hence, we have a point ( 4,1 )

For x = 5, since 5 is greater than 3, we use the piece of the function under x≥3

f(x) =  x - 3

f(5) =  (5) - 3

f(5) = 5 - 3

f(5) = 2

Hence, we have a point ( 3,2 )

Therefore, the table of the function is;

x      f(x)

1       8

2      5

3      0

4      1

5      2

Which answer shows 0.00897 written in scientific notation?
mamaluj [8]

Answer:

d) 8.97*10^{-3}

Step-by-step explanation:

Move the decimal 3 spaces to the right so that way the decimal can be between the first two numbers. When you move the decimal to the right, it makes the exponent negative, when it moves to the left, it makes it positive
