Answer:

4⁰ is the answer

Step-by-step explanation:

because first you change the division sign to a multiplication sign because they are the same and then multiply the terms with same base by adding their exponent which looks like this 4⁵-⁷+²

What is the x intercept for y=(2x(x-3))/(x-1). ?

Ainat [17]

Answer:

( 0,0) and (3,0)

Step-by-step explanation:

y=(2x(x-3))/(x-1)

Set y = 0

0 =(2x(x-3))/(x-1)

Multiply each side by x-1, which makes x not equal to 1

0 =(2x(x-3))

Using the zero product property

2x=0 x-3 =0

x=0 x= 3

The x intercepts are x=0 x= 3

( 0,0) and (3,0)

expeople1 [14]

Answer:

The expression for two times the difference of 4 and a number is

$8(4-d)$

Step-by-step explanation:

To Find:

Write an expression for Eight times the difference of 4 and a number.

Solution:

Let the Unknown number be 'd'

Difference of 4 and d = ( 4 - d )

So One Time Difference of 4 and d = 1× ( 4 - d )

∴ Two Times Difference of 4 and d = 2× ( 4 - d )

∴ Eight Times Difference of 4 and d = 8× ( 4 - d )

The expression for Eight times the difference of 4 and d. will be

$8(4-d)$

The expression for Eight times the difference of 4 and a number is

$8(4-d)$
