why does the multiplication property of equality not allow us to divide both sides of an equation by zero

Answers

Answer 1

Answer:

Answer:

Yeah, it doesn't...and it won't happen

Step-by-step explanation:

Because dividing with zero isn't a "thing" in math. Let's say you have 12 cookiesbut you're saying you are going to divide among zero people? See? It doesn't even have a real answer because no action happens, but if you said you would split the 12 cookies among 6 people that would means each person would get 2. So multiplying and dividing with zero isn't real math, that's why it doesn't work with equations and math in general.

An expression is shown below. What is the product of the two factors ?

Answers

Answer: The required product is $x^2.$

Step-by-step explanation: We are given to find the product of the following two factors.

$P=(x^(4)/(3))(x^(2)/(3)).$

We will be using the following property of exponents:

$a^x* a^y=a^(x+y).$

We have

$P\n\n=(x^(4)/(3))(x^(2)/(3))\n\n=x^(4+2)/(3)\n\n=x^(6)/(3)\n\n=x^2.$

Thus, the required product is $x^2.$

Simplify the expression....
you have...
$( x^{ (4)/(3) } )( x^{ (2)/(3) } )$
simplifying it...
$x^(2)$
The product of the two factors....
Thus, your answer.

8x-2=-9+7x Can someone help me?

Answers

Answer:

x = -7

Step-by-step explanation:

Start with your given equation.

8x - 2 = -9 + 7x

Next, subtract 7x from both sides of the equation and add like terms.

x - 2 = -9

Finally, add 2 to both sides of the equation and add like terms.

x = -7

Answer:

Step-by-step explanation:

x = -7

account :

8x-2=-9+7x

8x-7x=-9+2

X=-7

Select all functions that have a y-intercept of (0,5).f(x)=7(b)^x-2
f(x)=-3(b)^x-5
f(x)=5(b)^x-1
f(x)=-5(b)^x+10
f(x)=2(b)^x+5

Answers

Answer:

$f(x)=7(b)^(x)-2$

$f(x)=-5(b)^(x)+10$

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

Verify each case

case 1) we have

$f(x)=7(b)^(x)-2$

For x=0

$f(0)=7(b)^(0)-2$

$f(0)=7(1)-2=5$

therefore

The function has a y-intercept of (0,5)

case 2) we have

$f(x)=3(b)^(x)-5$

For x=0

$f(0)=3(b)^(0)-5$

$f(0)=3(1)-5=-2$

therefore

The function does not have a y-intercept of (0,5)

case 3) we have

$f(x)=5(b)^(x)-1$

For x=0

$f(0)=5(b)^(0)-1$

$f(0)=5(1)-1=4$

therefore

The function does not have a y-intercept of (0,5)

case 4) we have

$f(x)=-5(b)^(x)+10$

For x=0

$f(0)=-5(b)^(0)+10$

$f(0)=-5(1)+10=5$

therefore

The function has a y-intercept of (0,5)

case 5) we have

$f(x)=2(b)^(x)+5$

For x=0

$f(0)=2(b)^(0)+5$

$f(0)=2(1)+5=7$

therefore

The function does not have a y-intercept of (0,5)

What is a fraction

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

In question, let's assume that the number is x then according to the question

(1/3)x = x - 12

x = 3x - 36

36 = 3x + x

36 = 4x

x = 18 hence, it will be correct.
