Answers

Answer 1

Answer:

y=−16−4x

Step-by-step explanation:

Add 4x to both sides.

−y=16+4x

Multiply both sides by -1

y=−16−4x

Step-by-step explanation:

Explaining the Concept:

To get the perimeter of this square, we will first get the value of one side

Since all the sides of a square are equal, we will find the length of one of the side from the triangle EOF

Finding the length of one side of the triangle:

In triangle EOF:

Using the pythagoras's theorem

EO²+OF² = EF²

(5)² + (5)²=  side²       [since EF is a side of the square]

side²=  50

side = √50

side = 5√2 units

Perimeter of the Square:

We know that the perimeter of a square is 4 times its side

Perimeter  = 4 * side

Perimeter = 4 * 5√2

Perimeter = 20√2 units

Step-by-step explanation:

For this test remember all questions have two answers. Please put the smaller answer in the first blank. Solve. x2=12

Answers

2.1      Solve  :    x2-12 = 0

Add  12  to both sides of the equation :

                     x2 = 12

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     x  =  ± √ 12  

Can  √ 12 be simplified ?

Yes!   The prime factorization of  12   is

  2•2•3

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 12   =  √ 2•2•3   =

               ±  2 • √ 3

The equation has two real solutions  

These solutions are  x = 2 • ± √3 = ± 3.4641 /This is the answer

What is a way to write this sentence as an algebraic inequality?

Answers

Answer:

It's C.

Step-by-step explanation:

Did the test

The inequality is y/9 - x > 21.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

x less than the quantity y divided by 9 is more than 21.

Now, writing the mathematical Inequality for the given statement is

x less than the quantity y divided by 9

y/9 -x

and, more than 21.

y/9 - x > 21

Hence, the inequality is y/9 - x > 21.
