The value of the equation 3ab - 9ab + 7ab is $\boxed{ab}$ .

Further explanation:

There are two properties.

1. The property of addition or property of sum.

2. The property of subtraction.

3. The property of division.

4. The property of multiplication.

Given:

The equation is 3ab - 9ab + 7ab.

Explanation:

Consider the equation S = 3ab - 9ab + 7ab.

The equation contains the two variables that are “a” and “b”.

In the equation we have two operations one is addition and another is subtraction.

Solve the above equation to obtain the value of the equation.

First add 3ab and 7ab.

$\begin{aligned}X&=3ab+7ab\\&=10ab\\\end{aligned}$

Now subtract 9ab from 10ab.

$\begin{aligned}S&=10ab-9ab\\&=1ab\\&=ab\\\end{aligned}$

The value of S is ab.

Hence, the value of the equation 3ab - 9ab + 7ab is $\boxed{ab}$ .

Find the coordinates of the vertices of each figure after the given transformation.

cricket20 [7]

Answer:

Z'(1, 5), K'(1, 0), C'(−1, −1), M'(−3, 2)

Step-by-step explanation:

According to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:

180°: [x, y] → [−x, −y]

Z(−1, −5) → Z'(1, 5)

K(−1, 0) → K'(1, 0)

C(1, 1) → C'(−1, −1)

M(3, −2) → M'(−3, 2)

Aleksandr [31]

Using proportions, it is found that out of the next 75 couples asked, 49 will have at least one spouse that prefers action movies.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Researching this problem on the internet, it is found that out of 150 couples initially surveyed, 26 + 25 + 12 + 22 + 13 = 98 couples had at least one spouse preferring action movies, hence the proportion is:

p = 98/150 = 0.6533.

Out of the next 75 couples, the amount is:

A = 0.6533 x 75 = 49

Hence, out of the next 75 couples asked, 49 will have at least one spouse that prefers action movies.
