Answer:

11/24

Step-by-step explanation:

We want to find the number 1/2 way between 1/2 and 2/3. Add them together and divide by 2

(1/4+2/3) ÷2

Get a common denominator of 12

(1/4*3/3 + 2/3 *4/4) ÷2

(3/12 +8/12) ÷2

(11/12) ÷2

Copy dot flip

11/12 *1/2

11/24

Find the product. If the result is negative, enter "-". If the result is positive, enter "+". -7(- a2 ) 2 ( -b3 ).

m_a_m_a [10]

Answer:

The product is positive, thus it is $\bold{+7a^4b^3}$

Step-by-step explanation:

The full question in proper notation is:

"Find the product. If the result is negative, enter "-". If the result is positive, enter "+".

$-7(-a^2)^2(-b^3)$ "

We have to work with it using Order of operations know as well as PEMDAS, thus expression inside parenthesis go first and exponents.

On this expression we have to work with exponents

$(-a^2)^2 = (-a^2)(-a^2) =a^4$

Thus we get

$-7(-a^2)^2(-b^3)=-7a^4(-b^3)$

Lastly we can work with multiplication and remembering that the multiplication of two negative signs becomes positive.

$-7(-a^2)^2(-b^3)=7a^4b^3$

So the final simplified expression is $\bold{7a^4b^3}$

What is the equation of a line that passes through (7,8) and has a slope of -3

Komok [63]

It is helpful to first plug this in to point-slope form (note that there are other ways to do this).

Using the form $y-y_1 = m(x-x_1)$ , you get $y-8=-3(x-7)$ . You can simplify this to get $y = -3x+29$ .
