It’s 2 because it starts at 6 and the next time the line meets a point is at (4,-1) you go down one and over two and you put x/y so it’s 2/1 which is 2. I think that’s right

M is the midpoint of AN, A has coordinates

maksim [4K]

Step-by-step explanation:

According to Question , M is the midpoint of AN, A has coordinates (-7,4), and M has coordinates (-4, -1).

Figure :-

$\setlength{\unitlength}{1 cm}\begin{picture}(20,12) \put(4,0.2){\line(0,-1){0.4}}\put(1,0){\line(1,0){6}} \put(3.8,-0.6){$\bf M(-4,-1) $} \put(1,-0.6){$\bf A (-7,4)$} \put(6.8,-0.6){$\bf N(x,y)$} \end{picture}$

Let the coordinates of N be ( x , y )

Now , according to Midpoint Formula , the midpoint of points say A(x , y) and B (x' , y') is given by ,

$\boxed{\blue{ \bf Midpoint =\bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) }}$

On using this formula ,

$=> Midpoint = \bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) \\ \\ => (-4, 1) = \bigg( \dfrac{x -7 }{2} , \dfrac{y + 4 }{2}\bigg) \\ \\ => -4 = \dfrac{x-7}{2} \\\\ => x - 7 = -8 \\\\ => x = 7 -8 \\\\ \boxed{\red{\sf=> x = -1 }} \\\\ => \dfrac{y+4}{2}=-1 \\\\=> y +4 = -2 \\ \\ y = -4-2 \\\\\boxed{\red{\sf=> y = -6 }}$

A substance is tested and has a ph of 7.0. how would you classify it? a. a strong acid b. a strong base c. a weak acid d. neutra

Eddi Din [679]

A substance is tested and has a Ph of 7.0. It would be a weak acid.

The correct option is (c) a weak acid .

What is the nature of substance if the pH is less than 7?

Acidity is defined as pH below 7. More than 7 pH is considered basic.
Each whole pH number below 7 is ten times more acidic than the next higher value since the pH scale is logarithmic.
For instance, pH 4 is 100 times (10 times 10) more acidic than pH 6, while pH 5 is ten times (10 times) more acidic than pH 4.

What is pH?

The pH scale determines how acidic or basic water is.
The range is 0 to 14, with 7 representing neutrality.
Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

PLEASE HELP!!!!! Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance t

Sveta_85 [38]

Answer:

The answer to your question is Advance = $35 and same-day = $40

Step-by-step explanation:

Advanced = a

Same-day = s

Equations

a + s = 75 ----- (I)

20a + 35s = 2100 ----- (II)

Process

1.- Solve the equations by elimination.

Multiply equation I by -20

-20a - 20s = -1500

20a + 35s = 2100

Simplify

0 + 15s = 600

Solve for s s = 600/15

s = $ 40

Substitute "s" in equation I to find "a"

a + 40 = 75

Solve for a

a = 75 - 40

a = 35
