-(1+7x)-6(-7-x)=36 what is x equal to

Mathematics
1 answer:
Katyanochek1 [597]3 years ago
5 0

Answer:

x = 5

Step-by-step explanation:

Step 1: Write equation

-(1 + 7x) - 6(-7 - x) = 36

Step 2: Solve for <em>x</em>

  1. Distribute: -1 - 7x + 42 + 6x = 36
  2. Combine like terms: -x + 41 = 36
  3. Subtract 41 on both sides: -x = -5
  4. Divide both sides: x = 5

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-(1 + 7(5)) - 6(-7 - 5) = 36

-(1 + 35) - 6(-12) = 36

-(36) + 72 = 36

-36 + 72 = 36

36 = 36

Which property tells us to multiply the powers to simplify
MaRussiya [10]
There are a couple of operations you can do on powers
We can multiply powers with the same base
x4⋅x2=(x⋅x⋅x⋅x)⋅(x⋅x)=x6
xa⋅xb=xa+b
This is an example of the product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

without dividing explain whether 5 1/6 divided by 3 5?8 is greater or less than 5 1/6 divided by 2 2/5.
Kazeer [188]

Answer:

less

Step-by-step explanation:

without dividing you can still see that you're dividing the number 5 1/6 into more small pieces when you divide by 3 5/8 than when dividing by 2 2/5. it's like how you know that dividing 100 by 3 is going to give you a smaller number than dividing it by 2 because when you divide 100 by 3 the groups will have smaller numbers because there are more groups.

Suppose that the relation S is defined as follows. S= {(4,9), (-9,4), (0, -9), (6, 6)} Give the domain and range of S. Write you
Shtirlitz [24]

Given:

The relation S is:

S=\{(4,9),(-9,4),(0,-9),(6,6)\}

To find:

The domain and range of S.

Solution:

If a relation is defined by the set of ordered pairs (x,y), then the domain is the set of x-values and range is the set of y-values.

Let R be a relation defined as R=\{(x,y):x\in R,y\in R\}, then Domain=\{x:x\in R\} and Range=\{y:y\in R\}.

The given relation is:

S=\{(4,9),(-9,4),(0,-9),(6,6)\}

Here, x-values are 4,-9,0,6 and the y-values are 9,4,-9,6.

So, the domain and range of the given relation S are

Domain=\{-9,0,4,6\}

Range=\{-9,4,6,9\}

Therefore, Domain=\{-9,0,4,6\} and Range=\{-9,4,6,9\}.
