The Japanese Yen corresponds to the American Dollar. If the exchange rate is 150 Yen for 1 Dollar, then a Japanese car sold in America for $10,000 will bring in 1,500,000 Yen. If the exchange rate changes to 120 Yen for each Dollar, then what price in Dollars would the car have to be sold in America to bring the Japanese 1,500,000 Yen?

Answer:A=6 B=-4.5

Step-by-step explanation:

We want to find the values of A and B such that the given system of equations has no solutions. We will find that the values of A and B can be:

B = -4.5

A = 6

A system of linear equations has no solutions when the lines are parallel (so the lines never do intercept).

Here the system is:

3x + 4y = A

Bx – 6y = 15

Remember that two lines are parallel if and only if they have the same slope and different y-intercept, then let's write both equations in the slope-intercept form:

y = A/4 - (3/4)*x

y = -15/6 + (B/6)*x

So we must have:

B/6 = -3/4

A/4 ≠ -15/6

From the first one we get:

B = (-3/4)*6 = -4.5

From the second one we get:

A  ≠ (-15/6)*4 = -10

Then from the given pairs, the only one that causes the system to have no solutions is:

B = -4.5

A = 6

Step-by-step explanation:

Since triangles YRZ and QRS are similar by AA, the ratio of their sides should be constant. Since RY=QY, let's call that side length y.

[tex]\dfrac{x+2}{y}=\dfrac{3x-8}{2y}[/tex]

Multiply both sides by 2y:

Answer:

7

Step-by-step explanation:

Hey, sorry if this is a little late, but think of the tiles in an arrangement where 4 fit into a rectangle type thing. Now, since you want to find the maximum number of boards, find the closest number that you can multiply by 4 to get something close to 30. Here, you can see that 7x4=28, which is both an even number and the closest number to 30 as you can get. So, the answer is 7.

Answer:

$160

Step-by-step explanation:

100/100 = 100 ÷ 100 = 100% = 1. Multiply a number by the fraction 100/100

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The company payment is $1440.

Carol's total cost is $610.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of the bill = $2,050

Company payment = 80% of the bill less the deductible

This means,

80/100 x 2,050 = 1640

Company payment.

= 1640 - 200

= $1440

Now,

Carol's total cost.

= 2,050 - 1440

= $610

Thus,

The company payment is $1440.

Carol's total cost is $610.

Answer:

Part A;

There are many system of inequalities that can be created such that only contain points D and E in the overlapping shaded regions.

Any system of inequalities which is satisfied by (-4, 2) and (-1, 5) but is not satisfied by (1, 3), (3, 1), (3, -3) and (-3, -3) can serve.

An example of such system of equation is

x < 0

y > 0

The system of equation above represent all the points in the second quadrant of the coordinate system.

The area above the x-axis and to the left of the y-axis is shaded.Part B:

Part B

It can be verified that points D and E are solutions to the system of inequalities above by substituting the coordinates of points D and E into the system of equations and see whether they are true.

Substituting D(-4, 2) into the system we have:

-4 < 0

2 > 0

As can be seen the two inequalities above are true, hence point D is a solution to the set of inequalities.

Also, substituting E(-1, 5) into the system we have:

-1 < 0

5 > 0

As can be seen the two inequalities above are true, hence point E is a solution to the set of inequalities.

Part C

:This part is different from yours because my equation is y> 4x + 3 and it's been a long time since I did that task and I don't remember anything. I hope you can do yours from my example.

Given that chicken can only be raised in the area defined by y > 3x - 4.

To identify the farms in which chicken can be raised, we substitute the coordinates of the points A to F into the inequality defining chicken's area.

For point A(1, 3): 3 > 3(1) - 4 ⇒ 3 > 3 - 4 ⇒ 3 > -1 which is true

For point B(3, 1): 1 > 3(3) - 4 ⇒ 1 > 9 - 4 ⇒ 1 > 5 which is false

For point C(3, -3): -3 > 3(3) - 4 ⇒ -3 > 9 - 4 ⇒ -3 > 5 which is false

For point D(-4, 2): 2 > 3(-4) - 4; 2 > -12 - 4 ⇒ 2 > -16 which is true

For point E(-1, 5): 5 > 3(-1) - 4 ⇒ 5 > -3 - 4 ⇒ 5 > -7 which is true

For point F(-3, -3): -3 > 3(-3) - 4 ⇒ -3 > -9 - 4 ⇒ -3 > -13 which is true

Therefore, the farms in which chicken can be raised are the farms at point A, D, E and F.

Answer:

Option A

Step-by-step explanation:

The triangle most likely got translated. A translation is a rigid transformation. Rigid transformed shapes have the same angle measure and side lengths.

Option A should be the correct answer.

Side Note: You can also tell that the markings on the triangle are the same. This means that the shapes are congruent. They are just in different positions.

The true statement is (a) the transformation is rigid because corresponding side lengths and angles are congruent.

From the figure, we have the following highlights

The above means that the transformation from one triangle to the other is a rigid transformation

Hence, the true statement is (a)

Answer:D

Step-by-step explanation:

Answer:

The correct option is D

D) The graph of function f(x) is shifted right 3 units and up 4 units

Step-by-step explanation:

Lets the function be y = f(x)

To shift the graph 3 units to the right, we add -3 to the x term of the function:

Function becomes y' = f(x-3)

Then to shift the graph up by 4 units, we add -4 to the y term of the function:

Function becomes:

y - 4 = f(x-3)

y = f(x-3) +4

g(x) = f(x-3) +4

Hence the correct option is D, as the graph is shifted to the right by 3 units and also shifted up by 4 units

Answer: The correct answer is D. The graph of function f is shifted RIGHT 3 units and up 4

Answer:

10.5

Step-by-step explanation:

Let E be the midpoint of OA  and F be the midpoint of OB. 

If point O is placed between A and B, then points E and F are placed on different sides from O. The segment OE has length 12÷2=6 cm and segment OF has length 9÷2=4.5 cm. Than EF=6+4.5=10.5 cm.

If point O is placed outside the segment AB, then point B is closer to point O than point A, because OA>OB. Since OE=6 cm and OF=4.5 cm, EF=6-4.5=1.5 cm.

If the order of points is A, O, B, then the midpoints of AO and OB will be separated by half the length of AB: (12 cm + 9 cm)/2 = 10.5 cm.

C and E

Step-by-step explanation:

Use the slope formula to first find the slope of the line.

The slope formula is y₂₋y₁ / x₂₋x₁ where (x₁ , y₁) is a point on the graph and (x₂ , y₂) is the other point on the graph. Substituting the values into the slope formula will give you 2 as the slope.

Now use the point-slope formula to find the correct answers.

Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope. Substitute both points into the formula (separately) to get C and E as your answers.
