4 0

Step-by-step explanation:

Given sequence is: 2,5,8,11,14

Here first term a = 2

Common Difference d = 3

\because \:  t_n = a +(n-1) d \\  \\  \therefore \: t_n = 2+(n-1) 3 \\  \\ \therefore \: t_n = 2+3n- 3 \\  \\  \huge \purple{ \boxed{\therefore \: t_n = 3n- 1}} \\  is \: the \: required \: explicit \: formula\\

If PQ = 3, QR = 2x, and PR = 3x, what is QR?
aniked [119]

Answer:

6

Step-by-step explanation:

It is ALWAYS helpful to sketch the appropriate figure.

That will make clear that 3x = x+4, by the definition of midpoint.

Then you solve the equation and you get x=2, so that PQ = 6.

Craig threw a handful of identically shaped buttons into the air then collected 14 bottoms that landed on the carpet. Is this sa
olga55 [171]

Answer:

possible?? but I think that there is a typo, and that there would not be a bias

Step-by-step explanation:

can we assume that there are no typos in the question

he threw BUTTONS in the air, and look at buttons that landed with the BOTTOMS facing up ??? in that case the weight might bias the orientation of the landing... I think that you have a typo and it just says that he collected 14 BUTTONS, in that case given that they are "IDENTICAL" we most likely can assume that there would be no bias (size color, texture are all the same)

1. What is the y-intercept?<br> 4x+5y = -15<br> a. (3, 0)<br> b. (0,-3)<br> c. (x, 0)<br> d. (y, 0)
kipiarov [429]

Answer:

The y-intercept is answer b. (0, -3)

Step-by-step explanation:

To find the y-intercept, fill in x with 0.

4x + 5y = -15

4(0) + 5y = -15

0 + 5y = -15

5y = -15

y = -3

So, the y-intercept would be (0, -3).

Is the following an identity or have no solution. 2(a-4)=4a-(2a+4)
mamaluj [8]
You multiply everything in the parenthesis by the number outside.
In this case its 2 and -1. the first part is 2a-8 the second part is 4a -2a+16a
so it looks like this 2a-8=4a-2a+16a.
combine like terms and get 2a-8=18a.
Subtract the other 2a from the other side and you have 8=16a
divide each side by 16 and you have 8/16 which is one half.

Write an equation that you can use to solve for x.<br><br> Enter your answer in the box.
faltersainse [42]
The given angle ( 47 degrees) and x are supplementary angles, which equal 180 degrees.
 
 So x would equal 180 degrees minus 47 degrees

This can be written as x = 180-47 

x = 133 degrees
