We know when there are 2 parallel lines we have vertical angles.

Answer:

NP=PQ

Step-by-step explanation:

p is MIDpoint of NQ so basically distance of N to P is equal to distance of P to Q

The relationship between NP and PQ if point P is the midpoint of NQ is:

- NP + PQ = NQ

- 1/2 x NQ = NP = PQ  

Given,

P is the midpoint of NQ.

We need to find the relationship between NP and PQ if point P is the midpoint of NQ

The midpoint between two points in a line always divides the line into two equal parts.

The sum of the divided parts is always equal to the original line.

Half of the original line is equal to each part.

Example:

A_____B_____C

B is the midpoint.

We have,

AC = AB + BC

1/2 x AC = AB = BC

We have,

P is the midpoint of NQ

Now,

N______P______Q

Since P is the midpoint we can say that,

NP + PQ = NQ

And,

1/2 x NQ = NP = PQ  

Thus the relationship between NP and PQ if point P is the midpoint of NQ is:

- NP + PQ = NQ

- 1/2 x NQ = NP = PQ

Answer:

y=43x−1

Step-by-step explanation:

The equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

For the given question.

The  line passes through the points-

(x1, y1) =  (−8,−7)  

(x2, y2) = (−4,−4).

Find the slope using formula;

slope = m = (y2 - y1)/(x2 - x1)

m = (-4 + 7)/(-4 + 8)

m = 3/4

The equation of the line in slope intercept form is found by;

y - y1 = m(x - x1)

y + 7 = (3/4)(x + 8)

y = (3/4)x - 1

Thus, the equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

Answer:

(x + y)² = 121

Step-by-step explanation:

Using the identity

(x + y)² - (x - y)² = 4xy , then

(x + y)² - 5² = 4(24) , that is

(x + y)² - 25 = 96 ( add 25 to both sides )

(x + y)² = 121

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the equation of motion

S = ut+1/2gt²

S is the height of fall

g is the acceleration due to gravity = 9.81m/s²

u is the initial velocity = 0m/s

t is the time = 6s

Substitute in the formula;

S = 0+1/2(9.81)×6²

S = 4.905×36

S = 176.58m

The shaft is 176.58m deep

Given the expression for distance

S = 16t²

Velocity V = dS/dt

V = 32t

Given v = 1100

1100 = 32t

t = 1100/32

t = 34.375secs

Substitute t = 34.375 into S = 16t²

S = 16(34.375)²

S = 18,906.25ft

Answer:

He could say that he is -15 feet as seen from the sea level

The given statement can be represented in an integer as -15.

Given that, Joe lives in a city that is 15 feet below sea level.

We need to find how could he represent his elevation as an integer

Whole numbers less than zero are called negative integers (-). These numbers are to the left of zero on the number line. Zero is neutral. It is neither positive nor negative.

Now, 15 feet below sea level can be represented as -15.

Therefore, the given statement can be represented in an integer as -15.

Answer:

10.375

Step-by-step explanation:

You can tell that 10 is going to be before the decimal because it's already a whole number, so all you have to do is figure out what 3/8 is as a decimal! In case you didn't know, to change a fraction to a decimal, you divide the numerator (the top number) by the denominator (the bottom number). In this case, you need to divide 3, the numerator, by 8, the denominator. 3/8 = 0.375.

So, put the 10 in front of the decimal point and you're done...the answer would be 10.375!

Answer:

x = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{7}[/tex] + x - [tex]\frac{2}{14}[/tex] = [tex]\frac{1}{7}[/tex]

Multiply through by 14 to clear the fractions

2x + 14x - 2 = 2 ( add 2 to both sides )

16x = 4 ( divide both sides by 16 )

x = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

x = ± 13

Step-by-step explanation:

Given

x² = 169 ( take the square root of both sides )

x = ± [tex]\sqrt{169}[/tex] = ± 13

Since 13 × 13 = 169 and - 13× - 13 = 169

The theorem that justifies this statement ∠4≅∠6 is; Alternate Interior Angles.

When two parallel lines are crossed by a transversal line, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These alternate interior angles are always equal.

From the given diagram, we see that ∠4 and ∠6 fall into the category of alternate interior angles.

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

[tex]midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

Put all values.

[tex]( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )[/tex]

As they are equal, their corresponding elements are equal.

[tex] - 8 = \frac{2 + x}{2} [/tex]

[tex] - 16 - 2 = x[/tex]

x = -18

[tex]4 = \frac{ - 9 + y}{2} [/tex]

[tex]4 \times 2 = - 9 + y[/tex]

[tex]8 + 9 = y[/tex]

[tex]y = 17[/tex]

Therefore, y = 17.

Therefore, H =( -18,17).
