Find x if the angles are complementary

Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

$1.50

Step-by-step explanation:

The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes.

This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes )

Answer:

The answer is all three

Step-by-step explanation:

The function that represents the draining of the aquarium is an illustration of a linear function.

All statements are true about the scenario.

The function is given as:

[tex]\mathbf{w(x) = 20 - 10x}[/tex]

A linear function is represented as:

[tex]\mathbf{y =mx + c}[/tex]

By comparing [tex]\mathbf{y =mx + c}[/tex] and [tex]\mathbf{w(x) = 20 - 10x}[/tex], we can conclude that:

[tex]\mathbf{w(x) = 20 - 10x}[/tex] is a linear equation

The slope of a function is the average rate of a function.

The slope of [tex]\mathbf{w(x) = 20 - 10x}[/tex] is 10

This means that, the aquarium is being drained at a rate of 10 liters per second.

So, we can conclude that, the following statement is also true.

The slope represents how fast the water is being drained.​

Lastly, when x = 0, we have:

[tex]\mathbf{w(0) = 20 - 10(0) = 20}[/tex]

This represents the initial volume of the aquarium.

So, we can conclude that, the following statement is also true.

The y-intercept of 20 is the initial amount of water in the aquarium

Hence, the three statements are true.

Answer:

150°

Step-by-step explanation:

The coordinates of the point on the graph of is (-4,2).

A function is defined as the relationship between input and output, where each input has exactly one output. The inputs are the elements in the domain and the outputs are elements in the co-domain.

If -4 is a solution of the equation f(x) = 2,

When giving the input as  -4 the output will be 2.

Thus these can be written in ordered pair as (-4,2).

Hence, the coordinates of the point on the graph of is (-4,2).

Answer: quantity of water left over  = 0.96 gallons

Step-by-step explanation:

Given: Total quantity of water = 2.7 gallons

Water used for tomato plants = 0.98 gallons

Water used for peppers = 0.76 gallons

Total water used =  0.98 +0.76 = 1.74 gallons

Then, quantity of water left over = Total quantity of water - Total water used

= 2.7  - 1.74 gallons

= 0.96 gallons

Hence, quantity of water left over  = 0.96 gallons

Answer:

Step-by-step explanation:

The parenthesis can cancel because the lack of anything you can do in them, so that will leave you with 7m + 3 + 7m + 6

Next step is to add like numbers, you should start by adding 7m + 7m, which would be 14m.

Next would be to add 3 + 6, which is nine.

To end this equation, simply put 14m + 9

There is no one-number answer because we do not know what m is. So the equation 14m + 9 is the final answer.

Answer:

19 ; 2.8 hours

Step-by-step explanation:

Find the value of y for which the value of 8y+3 is 7 more than the value of 6y

8y + 3 = 7 + 6y

8y - 6y = 7 - 4

2y = 3

y = 3/2

y = 1.5

Let

Tom's rate = x

Sam's rate = y

Rate = 1 / time

Hence,

x = 1/7

Rate when they work together = 1/2

Tom's rate + Sam's rate = 1/2

1/7 + y = 1/2

y = 1/2 - 1/7

y = (7 - 2) / 14

y = 5/14

Since, rate = 1/time

Time = 1/ rate

Sam's time = 1/ rate = 1/y = reciprocal of y

Sam's time = 14/5 = 2.8 hours

2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes

Answer:

The correct answer is 55°

Answer: 3

Step-by-step explanation: Subtract 2 from both sides, leaving 2/3x=2. All you need to do now is find a number to multiply 2 by to get 6/3, which would be 3. 2=2 is a true statement.

The value of x in the equation (2/3)x + 2 = 4 is x = 3.

We have,

To solve the equation (2/3)x + 2 = 4, we can follow these steps:

- Start by subtracting 2 from both sides of the equation to isolate the term with x:

(2/3)x + 2 - 2 = 4 - 2

(2/3)x = 2

- To get rid of the fraction, multiply both sides of the equation by the reciprocal of (2/3), which is 3/2:

3/2 (2/3)x = 3/2 x 2

x = 3

Therefore,

The value of x in the equation (2/3)x + 2 = 4 is x = 3.
