For which equation is (4, 3) a solution?

y = x + 3
y = 3 x – 4
y = 2 x – 5
y = 2 x – 1

Answers

Answer 1

Answer:

y = 2 x – 5

Step-by-step explanation:

We can check all of them starting with equation 1.

y = x + 3

3 = 4 + 3

3 = 7

NOT TRUE

Equation 2:

3 = 3(4) - 4

3 = 12 - 4

3 = 8

NOT TRUE

Equation 3:

3 = 2(4) - 5

3 = 8 - 5

3 = 3

TRUE!

This means the last equation is not true.

Answers

Answer: The answer is A

Step-by-step explanation: I took the test on edge and got it right

The equation that is true for triangle QRS is -

Sin(100°)/3.5 = sin(S)/2.4

What is the law of sines?

The law of sines can be stated as -

Sin(α)/a = Sin(β)/b = Sin(γ)/c

Given is to identify the equation that is true for triangle QRS.

Refer to the triangle as shown in the image attached. Using the law of sines, we can write -

Sin(α)/a = Sin(β)/b

Sin(100°)/3.5 = sin(S)/2.4

Therefore, the equation that is true for triangle QRS is -

Sin(100°)/3.5 = sin(S)/2.4

2. The following list of prices is for a used original radio for a 1955 Thunderbird. The prices vary
depending on the condition of the radio.
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
a. Find the mean of the radio prices. Round to the nearest cent.

Answers

Answer: $275

Step-by-step explanation:

The mean of the radio price is $275 or 27500 cents

Given,

Price of used original radio for a 1955 Thunderbird:

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

We need to find the mean of these prices.

And round to nearest cent.

What is the mean of a set of values?

The mean is the average of all the given sets of values.

Example:

1,2,3,4

Mean = (1+2+3+4) / 4 = 10/4 = 2.5

Find the sum

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)

Sum = 3850

Find the number of prices.

= 14 prices

Find the mean.

= 3850 / 14

= 275

The mean radio price is $275.

Converting into cents.

$1 = 100 cents

$275 = 27500 cents

Thus the mean of the radio price is $275 or 27500 cents

Answer:

Step-by-step explanation:

I took the test and go it right!

The coordinate point for D is (5, 3). Therefore, option C is the correct answer.

What is a rhombus?

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.

Given that, Point A (2,2), Point B (3,4) and Point C (4,1)

The coordinate point for D that would make ABDC a rhombus.

So, the coordinate point for D is (5, 3).

Therefore, option C is the correct answer.
