Find the equation of the line that passes through 5,4 and 5,6

2 answers:

6 0

Answer: x = 5

Justification:

Realize that this two points are one directly (vertically) over the other.

This is they define a vertical line which is a line parallel to the y-axis.

That means that the line has a constant value of x, I mean the value of x is the same for every y.

The equations of this kind of lines is x = constant, and the constant, as you can notice, is the value of x which is 5 for both points.

So, the answer is x = 5.

As you see, this relation is not a function, because given the value of y you cannot know the value of x (there are infinite y-values that meet the condition x = 5).

Answer:

Step-by-step explanation:

$log_{4}$ ( x² - 6x ) = 2

4² = ( x² - 6x )

x² - 6x - 16 = 0

- 6 = - 8 + 2

- 16 = - 8 * 2

( x - 8 )( x + 2 ) = 0 ⇒ $x_{1}$ = - 2 , $x_{2}$ = 8

Jacob is mixing salt with

77julia77 [94]

The number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.

<h3>How to interpret the division? </h3>

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, $a \div b = a$ divided in b equal parts.

Also, we can write: $a \div b = a \times \dfrac{1}{b}$

(it is since $a = a times 1 so a/b = 1 \times (a/b) = (1/b) \times a$ )

The given table is:

Tablespoons of salt Cups of water

8 2

16 4

24 6

2 cups of water gets 8 tablespoon of salt.

Then 1 cup of water gets 8/2 = 4 tablespoons of salt. (divided the numbre of cups of water and number of tablespoons of salts in 2 equal parts).

This pattern remains same for other rows of the table, since we have:

1 cup of water gets 8/2 = 16/4 = 24/6 = 4 tablespoons of salt.

Thus, the number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.

Can somebody explain to me how to do problem 1?

Brut [27]

Answer:

Two spaces left

Step-by-step explanation:

Basically, you have to plot the points on the graph. The first number in the brackets is the x value and the other one is the y value. You would plot -2 on the x-axis. Since the other value is 0, you have to move left two spaces.

Which expression is equivalent to 3-(-5)

Helen [10]

Here is the equation:

$3-(-5)$

When you're subtracting a negative number from a positive number, the sign will change. The - sign will become + and the negative number becomes positive.

$3- \rightarrow 3+ \\ -5 \rightarrow 5$

Here is your new equation:

$3+5$

All you need to do is add 3 and 5.

$3+5=8$

That means your answer is 8.
