Right hand side,
11 + 8 = 9
Left hand side = Right hand side
Hence, This is true.
B. 16 = 16
Left hand side = Right hand side
Hence, This is true.
C. 16 - 4 = 7 + 6
Left hand side;
16 - 4 = 12
Right hand side,
7 + 6 = 13

2. How far is Supermarket B from your house? (Round of your answer to the nearest whole number)
3. How far are the supermarkets from each other? (Round of your answer to the nearest whole number)
Answer:
13meters far from the supermarket
The distance between Supermarket A and Supermarket B is 35 units.
What is distance formula?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.

Slope and y intercept please help im stuck on this problem
A producer received rupees 10000 when the price of a commodity was rupees 100 per unit. The receipts increased to rupees 15000 when price increased by rupees 20.Calculate the elasticity of supply?
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

are there options to the question or do you have to write it
9514 1404 393
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

Step-by-step explanation:
Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?
A. Find the answer.
B. Write a formula for the problem.
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
A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from Earth, how long will it take the rocket to make the trip from Earth to the satellite? (Hint: Divide the distance to the satellite by the speed.) Write your answer in scientific notation.
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

2(5x - 3) - 4 = x + 4 solve for x and show work
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

The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to
3.3 in 2014. During this time period, the land area of Iceland was 100,250 square kilometers. By how many
people did Iceland's population increase from 1990 to 2014?
A 330,825
B 132,330
C 125,312
D 80,200
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.

An emperor penguin travels a distance of 70 miles each year back to the place of its birth. If that same penguin moves at a speed of 2.4 miles per hour, the function d = 70 – 2.4t represents its distance d from its birthplace t hours after it has started its journey home. Find the zero of this function.
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
