Answer:

-9x +6

Step-by-step explanation:

The usual statement of the distributive property tells you how this works:

a(b + c) = ab + ac

-1(9x -6) = (-1)(9x) +(-1)(-6) = -9x +6

If the volume of a sphere is 256π/3 what is the radius?

Rzqust [24]

Answer:

Step-by-step explanation:

The volume of a sphere is equal to 4/3πr³.

Set up the equation;

4/3πr³=256π/3

Multiple both sides by 3/(4π):

r³=64

r=∛64=4 (ans)

Which two values of x are roots of the polynomial below?

Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

$x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}$

3. Solve the square root:

$x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}$

$x=\frac{-5+-\sqrt{25-28} }{2(1)}$

$x=\frac{-5+-\sqrt{-3} }{2(1)}$

4. Simplify the rest:

$x=\frac{-5+-\sqrt{-3} }{2}$

5. Separate the solutions:

$x=\frac{-5+\sqrt{-3} }{2} , x=\frac{-5-\sqrt{-3} }{2}$

Thus, options B and C are the answers.

hope this helps!

John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even n

Juli2301 [7.4K]

Even numbers
so each dice has numbers
1,2,3,4,5,6
the eve numbers are
2,4,6
odd are others
1,3,5
so 1/2 are odd

therefor 1/2 of 60 is how many times it would get even
1/2 of 60=1/2 times 60=30

No not good predicition
my prediction would be 30 tiemes

53 pts!! The function f(x)= 7^x+1 is transformed to function g through a horizontal compression by a factor of 3. What is the eq

e-lub [12.9K]

The value of k will be 3 if the function is transformed by compression factor of 3

Step-by-step explanation:

The horizontal stretch or compression for a function f(x) is given by g = f(bx) where b is a constant. If b> 0 then the graph of function is compressed.

As it is given in the question that he function is transformed by a compression factor of 3.

Given function

$f(x) = 7^x+1\\To\ transform\\g = f(bx)\\g = 7^{3x}+1$

The value of k will be 3 if the function is transformed by compression factor of 3
