Which table shows a proportional relationship between x and y?

Answer:

x = 8

Step-by-step explanation:

The measure of an arc is equal to the angle at the centre subtended by the arc.

The sum of the 3 arcs = 180° , then

5x + 6 + 83 + 51 = 180

5x + 140 = 180 ( subtract 140 from both sides )

5x = 40 ( divide both sides by 5 )

x = 8

21

Step-by-step explanation:

because

7b

=7 × b

=7 × 3(b=3)

=21

Answer:

The Parenthesis tells you what operation to do first.

Step-by-step explanation:

Why? Because you have to get rid of the Parenthesis before getting rid of anything else in the problem.

Answer:

g(x) = -2 • 5^x

Step-by-step explanation:

the reflection across the x-axis makes the equation negative. the 2 is the verticals stretch.

(also got the answer correct on a test)

The function f(x) after a vertical stretch by a factor of 2 and a reflection across the x-axis becomes [tex]\rm g(x) =-2\times (5)^x[/tex] and this can be determined by using the rules of transformation.

Given :

[tex]\rm f(x) = 5^x[/tex]

The following steps can be used in order to determine the function after the given transformation:

Step 1 - The rules of transformation can be used in order to determine the function after the given transformation.

Step 2 - Write the given function.

[tex]\rm f(x) = 5^x[/tex]

Step 3 - Now, stretch the graph of the above function vertically by a factor of 2. So, the function of the graph obtained is:

[tex]\rm h(x) =2\times (5)^x[/tex]

Step 4 - Now, take the reflection of the graph obtained in the above step about the x-axis. So, the function of the graph obtained is:

[tex]\rm g(x) =-2\times (5)^x[/tex]

Therefore, the correct option is D).

Answer:

9:45am.

Step-by-step explanation:

In 6 Hours and 20 minutes, there's 380 minutes.

Because 60 x 6 + 20 =380

So you go back 380 minutes from 4:05.

4:05pm minus 380minutes= 9:45am.

The time did I set off from Boston is 9:45 am.

Given that,

Based on the above information, the calculation is as follows:

In 6 Hours and 20 minutes, there should be380 minutes.

As [tex]60 \times 6 + 20 =380[/tex]

So it should be like

= 4:05 Pm - 380 minutes

= 9:45 am

Answer:I would say that the answer is 700 is the answer is incorrect my apologies.

Step-by-step explanation: Ms.Li spent $840 on vacation, She spent 2/3 of the amount on a train ticket and 1/2 of the remaining amount on food. How much did she spend on ticket and food altogether= 840  2/3 = 560

840-560 = 280

half of 280 = 140

560+140 = 700

x > -30/-2

x>15

Hence the solution is x>15

Answer:

90 Degrees

Step-by-step explanation:

This is a very cool theorem. When the longest side of a triangle is the diameter of the circle, which in the picture you can see it is, the angle opposite to it is ALWAYS 90 degrees. Remember that the points have to be on the circle for this theoroem to work. I forget what the theoroems is called, but it is very helpful.

Answer:

1=(5,-2) 2=(1,4)

Step-by-step explanation:

Answer:

= 7700

Step-by-step explanation:

income : savings = 15 : 4

income = 15x

savings = 4x

but it is given that savings = 2800

therefore

4x = 2800

x = 700

income = 15x

          = 15*700

          = 10500

expenditure = income - savings

               = 10500-2800

               = 7700
