I know this becasue I did it before but also becasue I checked my work with a slope calculator. You should use one if you don't want to hand do the work. If you do want to do the work it is y2-y1 over x2-x1 :)

Answer:

x= 14/9 = 1 5/9

Step-by-step explanation:

Use the distributive property to multiply 2 by 5x−3.

2(5x−3)−4=x+4

Subtract 4 from −6 to get −10.

10x−6−4=x+4

Subtract x from both sides

10x−10=x+4

Combine 10x and −x to get 9x.

10x−10−x=4

Add 10 to both sides.

9x−10=4

Divide both sides by 9.

x=  14/9

Answer: Time taken =1.25 x 10^1 hours 0r  4.5 x 10^4s

Step-by-step explanation:

Step 1

how long will it take the rocket to make the trip from Earth to the​ satellite = Time taken for the rocket to make the trip from Earth to the​ satellite

Speed = Distance / Time ,

Time = Distance / speed

Step 2-- solving

Time = Distance / speed

Time=2.5×10^5 miles/2.0×10^4 miles per hour

=12.5 hours  = 1.25 x 10^1 hours

or 1.25 x 10^1 hours  x 3600 = 45,000 seconds = 4.5 x 10^4s

Answer:

0

Step-by-step explanation:

The formula for slope is [ y2-y1/x2-x1 ].

0/-5

-0/5

Since the numerator is 0, the slope is 0.

Answer:

Price Elasticity of Supply = 1.25

Step-by-step explanation:

Price      Quantity        Total Revenue ( P x Q)

100     10000/100 = 100       10000

120      15000/120 = 125        15000

Price Elasticity of supply is change in quantity supplied, due to change in price. Formula : (dQ / dP) x (P / Q)

(125 - 100) / (120 - 100)   x (100/100)

= 25/20 = 1.25

Answer:

13meters far from the supermarket

The distance between Supermarket A and Supermarket B is 35 units.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

From the given coordinate plane, Supermarket A is at (12, 9), House is at (0, 0) and Supermarket B at (-16, -12).

1) Distance between Supermarket A and your house is

Substitute (x₁, y₁)=(12, 9) and (x₂, y₂)=(0, 0) in distance formula, we get

Distance = √[(0-12)²+(0-9)²]

= √144+81

= √225=15 units

2) Distance between Supermarket B and your house is

Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(0, 0) in distance formula, we get

Distance = √[(0+16)²+(0+12)²]

= √256+144

= √400=20 units

3) Distance between Supermarket A and Supermarket B is

Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(12, 9) in distance formula, we get

Distance = √[(12+16)²+(9+12)²]

= √28²+21²

= √1225=35 units

Therefore, the distance between Supermarket A and Supermarket B is 35 units.

Answer:

It crosses through 0,-23) and (4.6,0)

Step-by-step explanation:

Given:

The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to  3.3 in 2014.

Land area of Iceland = 100,250 square kilometers.

To find:

The Iceland's population increase from 1990 to 2014.

Solution:

Land area of Iceland is constant, i.e., 100,250 square kilometers.

The population density of Iceland, in people per square kilometer of land area in 1990 is 2.5.  So, the population in 1990 is

[tex]2.5\times 100,250=250,625[/tex]

population density of Iceland, in people per square kilometer of land area in 2014 is 3.3.  So, the population in 2014 is

[tex]3.3\times 100,250=330,825[/tex]

The Iceland's population increase from 1990 to 2014 is

[tex]330,825-250,625=80,200[/tex]

Therefore, the correct option is D.

Answer:

a. $22.2

b= 13.32/x=3/5

Step-by-step explanation:

13.32/x=3/5

13.32×5=66.6

66.6/3=22.2

x(present cost)=$22.2

Answer:

22.20$

3/5 * cost = 13.32

Step-by-step explanation:

3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)

to solve

5/3 to cancel out 3/5 and isolate the cost

5/3 * 13.32 = 22.20

Answer:

  3x -4y = 12

Step-by-step explanation:

There are a number of different forms of the equation of a line. A few are ...

  y = mx + b . . . . slope-intercept form

  y -k = m(x -h) . . . . point-slope form

  x/a +y/b = 1 . . . . intercept form

  ax +by +c = 0 . . . . general form

  ax +by = c . . . . standard form

In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.

__

Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...

  x/4 +y/(-3) = 1

Multiplying this by 12 clears the fractions and gives us standard form:

  3x -4y = 12

Answer:

29.17 hours

Step-by-step explanation:

to find the zero of the function, set d to equal zero, so

0 = 70 - 2.4t

-70 = -2.4t

-70/-2.4 = t

29.17 = t
