<u>Algebra I</u>

Step-by-step explanation:

<u>Step 1: Define</u>

-29 = 9 - 6k - 2k - 1

<u>Step 2: Solve for </u><em><u>k</u></em>

  1. Combine like terms:                                                                                       -29 = 8 - 8k
  2. [Subtraction Property of Equality] Subtract 8 on both sides:                      -37 = -8k
  3. [Division Property of Equality] Divide -8 on both sides:                              37/8 = k
  4. Rewrite/Rearrange:                                                                                        k = 37/8

<u>Step 3: Check</u>

<em>Plug in k into the original equation to verify it's a solution.</em>

  1. Substitute in <em>k</em>:                                                                                                -29 = 9 - 6(37/8) - 2(37/8) - 1
  2. Multiply:                                                                                                           -29 = 9 - 111/4 - 37/4 - 1
  3. Subtract:                                                                                                          -29 = -75/4 - 37/4 - 1
  4. Subtract:                                                                                                          -29 = -28 - 1
  5. Subtract:                                                                                                          -29 = -29

Here we see that -29 does indeed equal -29.

∴ k = 37/8 is the solution to the equation.

How do you write sentences 10+k=4K
Andrei [34K]
K added to 10 gives you 4 times the value of K.

If you wanted to solve the expression:

Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k

If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.

We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k

Use compatible numbers to estimate the quotient394.6 divided by 9
laiz [17]

Answer:

45

Step-by-step explanation:

As a first rough estimate:  divide 390  by 10, obtaining 39.

Another reasonable approximation could be obtained by dividing 450 by 9 and 360 by 9, obtaining 50 and 40.  Since 390 is roughly halfway between 360 and 450, estimate that the quotient is approx 45 (halfway between 40 and 50).

A flowerbed is to be 3m longer than its width.the flowerbed will have an area of 70m²​
melomori [17]
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0

SOLUTION

Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²

In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70

What is the domain of the function in this table
lina2011 [118]

For this case we have that by definition, the domain of a function is given by the set of all the possible input values of the function. That is, the values that the variable "x" takes.

Also, it can be said that it is the set of all the values for which the function is defined.

The table shows that "x" takes the following values:

{3,4,5,6}

Answer:

Domain: {3,4,5,6}

Option C
