What are two integers whose product is 0

guapka [62]

Answer:

At least one of the integer must be equal to zero to obtain the product zero

Step-by-step explanation:

we know that

When multiplying integers , if one or both of the integers is 0, then the product is 0.

The multiplication property states that the product of any number and zero is zero.

a*(0)=0

F(x)= x squared -3x + 2 divided by 3x squared + 9 x -12

VashaNatasha [74]

Answer:

=(x-2)/3(x+4)

Step-by-step explanation:

F(x)=x²-3x+2/3x²+9x-12

Using mid term break formula

=x²-2x-x+2/3(x²+3x-4)

=x(x-2)-1(x-2)/3(x²+4x-x-4)

=(x-2)(x-1)/3{x(x+4)-1(x+4)}

=(x-2)(x-1)/3(x-1)(x+4)

Cancelling (x-1)

We get

=(x-2)/3(x+4)

Hope it helps :)

In March, there will be two conferences: one for math and one for history. So far, 7 people have signed up for the math conferen

otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.
