Find the range and domain of the following function

Find The Range And Domain Of The Following Function

Answers

Answer 1
Since we don’t see an end on the X value we know that every number could be X. This mean X is an element of reels, so the domain answer is XER, the y however is over -2, so y>-2 but it can be any number above that so it is also an element of reels. So y>-2,YER would be the range

X=112
Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!

Answer:

x = 118°y = 84°

Step-by-step explanation:

We observe that:

x = y + 22 as exterior angle of the triangle is the sum of non-adjacent interior angles.

Also:

x = 118 as corresponding angles formed by two parallel lines and a common transversal.

Find the value of y:

y = x - 22y = 118 - 22y = 84

I need help on the second part where you identify if the examples are equal​

Answers

Answer:

No equal

Step-by-step explanation:

Let's make it simpler:

a/b = x, c/d = y, e/f = z

We have:

(x/y)/z = x/y*1/z = x / (yz) x/(y/z) = x*z/y = xz/y

Further steps

(a/b) / (ce/df) = (ace) / (bdf)(ae/bf)/(c/d) = (ae/bf)*(d/c) = (ade)/(bcf)

As you see the end results are different

do you need to regroup to subtract 881 from 4,986 how do u know?

Answers

no because

4986

881

4 1 0 5

there is no regrouping because every top number is equal to or larger than the bottom number

There is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The two numbers are:

881 and 4986

As we know,

The term PEDMAS describes the sequence in which arithmetic operations must be carried out in an equation.

According to this rule, operations should be carried out in the following order: parentheses, exponents, multiplication or division, then addition or subtraction.

After applying the concept of arithmetic operation:

= 4986 - 881

= 4105

Thus, there is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

281-48=48-u-48 ( substracting 48 on both sides )

Option 1 does not represent a function.

A function is a relation in which no two ordered pairs have the same input (x-values) and different outputs (y-values).

In option 1, x = 1 has two corresponding y-values: -6 and 9. Therefore, the given relation in Option 1 does not represent a function.

Answer:     x = ⁵/₃;    x = 5

Step-by-step explanation:

Since       (20)        =        (-3)                     [we can cross multiply]

            (x²- 25)                (5-x)

⇒                     (20)(5 - x) = (-3)(x² - 25)       [expand the brackets]

⇒                     100 - 20x = -3x² + 75          [make the equation equal to zero]

⇒             3x² - 20x + 25 = 0                      [expand the middle term using

                                                                     appropriate factors of the product

                                                                     of the terms a and c (3 × 25)]

⇒       3x² - 15x - 5x + 25 = 0                      [factorize the terms]

⇒            (3x -  5 ) (x - 5)  = 0                      [using the knowledge that for the

                                                                       produc to be 0, one of terms

                                                                       must be zero]

⇒            (3x -  5 ) = 0     OR   (x - 5)  = 0     [solve for x in each case]

⇒                       x = ⁵/₃    OR           x = 5

 

find the sum of the first 10 term of geometric sequence 1,4,16,64...
with solutions ​

Answers

Answer:

Step-by-step explanation:

1 × 4 = 4

4 × 4 = 16

16 × 4 = 64

64 × 4 = 256

256 × 4 = 1024

1024 × 4 = 4096

4096 × 4 = 16384

16384 × 4 = 65536

65536 × 4 = 262144

so the sum of the first 10 term = 1 + 4 + 16 + 64 + 256 + 1024 + 4096 + 16384 + 65536 + 2622144 = 349525
