Answer:
x = 2 and y = 1
Step-by-step explanation:
Given equations are :
2x-y=3 ...(1)
3x+y=7 ...(2)
Add equation (1) and (2) as follows :
2x-y + 3x+y = 3 + 7
2x + 3x = 10
5x = 10
x = 2
Put the value of x in equation (1)
2(2)-y=3
4-y = 3
y = 4-3
y = 1
Hence, the solution of the given equations are (2,1).

Melissa has $100 in the bank. She plans to deposit $40 per week until she reaches $500. What is the rate of change? Explain what the rate of change means in the context of the problem. *
Answer:
$40 per week
Step-by-step explanation:
Step one:
Given data
the initial amount is = $100
the total amount= $500
let the number of weeks be x
Step two:
The expression for the scenario is
[tex]500= 100+40x-------1[/tex]
From the expression above, the rate of the change is $40 per week.
this means that in every week the account will be increased by $40

1.Could 18 in, 6 in, and 13 in, form a triangle?
2. Could 34 km, 27 km, and 58 Km, form a triangle?
3. Could 29 ft, 38 ft, and 9 ft, form a triangle?
4. Could 12 cm, 12 cm, and 25 cm, form a triangle?
5. Could 31 yd, 14 yd, and 19 yd, form a triangle?
Answer:
1. yes
2. yes
3. no
4. no
5. yes
Step-by-step explanation:
The questions you're asking relate to the Triangle Inequality Theorem, which states that the two smallest sides (ex. 6 and 13) have to be of greater value than the largest side (ex. 18)
1. 6+13>18
2. 34+27>58
3. 29+9=38 (since the value of the two smallest sides are equal, it does not apply to the Triangle Inequality Theorem, and therefore won't be a triangle)
4. 12+12<25
5. 19+14>31

Three brothers, Andy, Bob, and Curly, take a taxi together home from the
airport.
Their homes lie along the same route;
• Andy’s is 21 km from the airport,
• Bob’s is 42 km, and
• Curly’s is 63 km.
If the taxi fare is $2.00 per km, try to find at least two possible fair ways for each
of the three travellers to pay the driver (not including the tip)?
I really need help on this cab someone answer this please
Answer:
See explanation
Step-by-step explanation:
not sure what class this is for but I\ll try. Each traveller has a 21 km drive so their fare should be equal.
method 1) each traveller can pay for 21 km worth when they get out
method 2) Curly can pay the full fare and Andy and Bob can pay him back later (they're brothers so this should be easy to manage)

Find the nth term of this quadratic sequence.
3, 11, 25, 45
Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

Step-by-step explanation:
Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Answer:
x=6 is not a solution
Step-by-step explanation:
We can substitute 6 as x to find out:
5(6-3)=6+13
first, because of PEMDAS we'll do 6-3
5(3)=6+13
multiply 5 by 3 and add 6 and 13
15=19
Since the statement is not true, that means that x=6 is not a solution

20 points The supply and demand curves for a new style of silver earrings are shown. Where is the equilibrium point?
Answer:
It's the dot that's right in the middle of the rest, where the two lines meet.
Step-by-step explanation:
That's the equilibrium point.
The equilibrium point of the given graph is at (35, 90)
What are supply and demand curves?The demand curve shows the quantities of a particular good or service that buyers will be willing and able to purchase at each price during a specified period. The supply curve shows the quantities that sellers will offer for sale at each price during that same period.
Given that, the supply and demand curves for a new style of silver earrings are shown.
We need to find the equilibrium point,
We know that, On a demand and supply graph, the equilibrium point can be found where the demand and supply curves intersect. Price is on the axis on both the demand and supply curves, and quantity demanded is on the axis.
In our graph, the curves are intersecting at (35, 90)
Hence, the equilibrium point of the given graph is at (35, 90)

Rachel is planning to run an average of 6.4 miles over three consecutive days. On the first
day, she ran 6.6 miles, and on the second day, she ran 6.5 miles. What is the maximum
number of miles Rachel can run on the third day without going over the planned average of
6.4 miles per day?
The maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.
Maximum number of miles:Let x represent the maximum number of miles
Formulate
6.6+6.5+x÷3=6.4
Hence:
6.6+6.5=6.4×3
13.1+x=19.2
x=19.2-13.1
x=6.1 miles
Inconclusion the maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.

Dione is designing a water fountain for the lobby of a new hospital. She knows that the fountain will have a circular pool with water projected upward at a constant rate from the center of the pool. She needs to determine the maximum height, so she uses a linear model to represent the situation.
Answer:
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model
Step-by-step explanation:
Here, we want to choose the correct option
As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola
So the correct answer in this case is that;
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

find the value of x.
Answer:
2
Step-by-step explanation:
Since they are similar triangles then the ratio will be the same on all sides.
You know the one side 5 is the same ratio to 5x so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.
so the missing side x times x will equal the big size of the bigger triangle which is 4
x times x = 4 can only be 2

The temperature in a town is 34.1°F during the day and -8.6°F at night. Find the difference in the temperatures.
Answer:
the difference is 25.5
Step-by-step explanation:
34.1 - 8.6 = 25.5
[tex]42.7^{\circ}F[/tex]
Subtract the number with the smallest value from the number with the biggest value to determine the difference between two numbers.
Temperature in a town during the day [tex]=34.1^{\circ}F[/tex]
Temperature in a town during the night [tex]=-8.6^{\circ}F[/tex]
