Answer: A' is the point representing the equilibrium price.

Step-by-step explanation:

Since we have given the figure in which we have "Demand Curve and Supply Curve":

Both are intersecting at A and

Demand curve has the highest point at B.

Supply Curve has the highest point at C.

Equilibrium is the point at which both the curves get intersected.

Here, we can see that at 'A' both get intersected and

Equilibrium price will be $3. and equilibrium quantity will be 300 units.

Hence, 'A' is the point representing the equilibrium price.

leva [86]

Answer:

1. 19.375 inches

2. 8.808 km

Step-by-step explanation:

1. Diego's height - his brother's height

59.5 - 40.125

19.375 inches

Therefore, Diego is 19.375 inches taller than his brother.

2. distance needed to run - distance covered

10 - 1.192

8.808 km

Therefore the runner has to run 8.808 kilometres left to run to finish the race.

Given the following relations on the set of all integers where (x,y)∈R if and only if the following is satisfied. (Check ALL cor

Wewaii [24]

Answer:

a) symmetric

b) symmetric, reflexive, transitive

c) antisymmetric

d) symmetric

Step-by-step explanation:

(a) x+y = 0

- this relation is not reflexive, because the only element that relates with itself is 0. x+x = 2x, x+x = 0 only if 2x = 0, hence x = 0. Since 0 relates with itself, then the relation isnt irreflexive either.

Note that for x,y such that x R y, we have that x+y = 0, therefore, y = -x.

-If x,y,z are such that x R y, y R z, then y = -x, z = -y = -(-x) = x. In general x does not relate with z because z=x and the relation isnt reflexive, thus the relation is not transitive. For example, if x = z = 2, y = -2, we have that xRy, yRz, but x does not relate with z.

- This realtion is symmetric due to the commutativity of the sum. If xRy, then x+y = 0, and y+x = x+y = 0, hence yRx. Therefore, the relation cant be antisymmetric, because every element different from 0 relates to its opposite. For example 2R-2, -2R2 but 2 ≠ -2.

b) x-y is an integer

Since we are taking the substraction of two integers, the result will always be integer. Hence, every pair of elements relate within each other. As a result, the relation is symmetric, reflexive and transitive. However, it is not irreflexive nor antisymmetric, because for example 4R4, and 4R8, 8R4, but 4 is not 8.

c) x = 2y

Note that x = 2x only if x = 0, so the relation is neither reflexive nor irreflexive.

The relation is not symmetric, for example, 4R2 because 4 = 2*2, but 2 does not relate with 4, because 4*2 = 8. However, the relation is antisymmetric, because if xRy, yR2, we have

x = 2y

y = 2x = 2(2y) = 4y

since y = 4y, y should be 0, and x = 2*0 = 0. Therefore x=y = 0. The relation is antisymmetric.

The relation isnt transitive: 2R4, 4R8, but 2 does not relate with 8 because 8*2 = 16.

d) xy>1

since 0² = 0, 0 does not relate with itself, hence the relation is not reflexive. It is not irreflexive either, because, for example, 2*2 = 4 > 2, thus 2 relates with itself.

The relation is not transitive: 1 relates with every integer greater than itself, but it does not relate with itself, for example 1R7 and 7R1 because 1*7=7*1 = 7 > 1, but 1*1 = 1, it is not greater than 1, hence 1 doesnt relate with itself. This also shows that the relation is not antisymmetric either, because 1R7, 7R1 but 1≠7. The relation, however, is symmetric due to the commutativity of the product. If xy > 1, then yx = xy >1 as well.

I hope that works for you!

Logan is buying equipment for the football team and the baseball team. He spends $40 on football uniforms, and he plans on purch

aleksandr82 [10.1K]

Answer:

The coordinate pair that represents this solution is (20 , 240)

Explanation:

We are given that:

1- Equation that represents amount paid on football team based on number of purchased footballs is:

y = 40 + 10x

2- Equation that represents amount paid on baseball team based on number of purchased baseballs is:

y = 200 + 2x

Now, Logan wants to spend the same amount of money on both teams. This means that the y value in both equations should be equal

He also wants to buy the same number of balls for the two teams. This means that the x value in both equations should also be equal.

Therefore, we would be getting the point of intersection between the two equations.

To do this, we will start by equating the two equations and solving for x as follows:

40 + 10x = 200 + 2x

10x - 2x = 200 - 40

8x = 160

x = 20

Then, we will use the x to substitute in any of the two equations:

Substituting in the first equation:

y = 40 + 10x = 40 + 10(20) = 240

Substituting in the second equation (as a check):

y = 200 + 2x = 200 + 2(20) = 240

Based on the above calculations:

If Logan bought 20 balls for each team, he will be spending $240 on each

Solution set is (20, 240)

Note: the graphical solution is attached.

Hope this helps :)
