Answer:

I believe it would be 14.

Step-by-step explanation:

The distance between 7 and -7 should be 14.

The length of NO is 14 units

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the length is given by:

d =√((x2 – x1)² + (y2 – y1)²)

We:

N= (7,-4) : x1 = 7 , y1 = -4

O = (-7,-4): x2 = -7 , y2 = -4

Using the formula with the given values:

d=√((-7 – 7)² + (-4 – (-4))²)

d=√((-14 )² + (0)²)

d=√196

d= 14

Therefore, the length of NO is 14 units

Answer:

  39°

Step-by-step explanation:

It is the same measure as the one labeled 6x-9, since these are vertical angles.

  4x +7 = 6x -9

  16 = 2x . . . . . . . . add 9-4x

  8 = x

  4x+7 = 4(8) +7 = 39

The angle is 39°.

10x + 400 - y = 100

Step-by-step explanation:

Answer:

50 people came to the play

Step-by-step explanation:

Let x be the amount of people that attended the play

10x=400+100

10x=500

divide by 10 on both sides

50 people came to the play

400+100=500

40 people is $400 for the props

10 people makes $100

Answer:

The average yearly change in the value of the card is $15/year

Step-by-step explanation:

Here in this question, we are interested in calculating the average yearly change in the value of the card.

From the question, we can see that the value of the baseball card has depreciated by $120, thus we simply want to calculate the average yearly charge in the card value.

Mathematically, that would be ;

the total depreciation value/ number of years

From the question, the total depreciation value is $120 while the number of years is 8

Thus; the average yearly change in value of the card = 120/8 = $15/year

Answer:

Step-by-step explanation:

The average speed is defined as the total distance traveled divided by the total time taken.

from A to B

distance= 100 miles

speed= 50 mi/h

speed= distance/time

time= distance/speed

time= 100/50

time= 2 hours

from B to C

distance= 100 miles

speed= 70 mi/h

speed= distance/time

time= distance/speed

time= 100/70

time= 10/7 hours

Average speed= total distance/total time

total distance= 200 mile

total time= 2+10/7= (14+10)/7= 24/7

Average speed= 200/24/7

Average speed= 200*7/24

Average speed= 1400/24

Average speed= 58.3 mi/hour

Answer:

[tex]y^7[/tex]

Step-by-step explanation:

If we want to simplify the expression [tex]y^9 \cdot y^{-2}[/tex], we have to note that exponent rules state that [tex]x^a \cdot x^b = x^{a+b}[/tex].

This means that if we add the exponents, that will be what we raise y to the power of.

[tex]9 + -2 = 9-2 = 7[/tex]

So [tex]y^7[/tex].

Answer:

y= -2x + 7

Step-by-step explanation:

So in slope intercept y will always equal something so you start with

y= mx + b

m = slope and b = y-intercept

so in this case it would first be

y = -2x + b

and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.

so you finally get

y=-2x+7

The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, 7).

And, The slope of the line is,

⇒ m = - 2

Now,

Since, The equation of line passes through the point (- 4, 7).

And, Slope of the line is,

m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - 7 = - 2 (x - (-4))

⇒ y - 7 = - 2 (x + 4)

⇒ y - 7 = - 2x - 8

⇒ y = - 2x - 8 + 7

⇒ y = - 2x - 1

Therefore, The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

Answer:

the total distance is 56 cm

Step-by-step explanation:

Given that the area of the bulletin board is 196 cm^2

Based on this, the total distance around the bulletin board is

But before that we need to find out the side

As the area of square is

= side^2

196 = side^2

So side = 14

Now there are four sides, so the total distance is

= 4 × 14

= 56 cm

Hence, the total distance is 56 cm
