Answer:

y - 6 = -(x - 5)

Step-by-step explanation:

Start with the general point-slope form y - k = m(x - h).

Here m = -1, h = 5 and k = 6, and so, after substitutions, we have:

y - 6 = -(x - 5)

A(3-x)=-2x+B if x=2 How do I find A and B what are the answers

irina1246 [14]

Answer:

$A=5,B=9\\\\or\ A=-9,B=-5$

Step-by-step explanation:

$A(3-x)=-2x+B\\\\Given\ x=2\\\\Substitute\ the\ value\ of\ x\\\\A(3-2)=-2\times 2+B\\\\A=-4+B\\\\A=B-4\\\\So\ the\ value\ of\ A\ is\ 4\ less\ than\ the\ value\ of\ B.\\\\When\ B=9\Rightarrow A=9-4=5\\\\When\ B=-5\Rightarrow B=-5-4=-9\\\\Hence\ A=5,B=9\\\\or\ A=-9,B=-5$

A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten y

lyudmila [28]

Answer: $69811

Step-by-step explanation:

Given : A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants.

One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. (1)

We know that the confidence interval is given by :-

Point estimate of mean ± Margin of error

From (1) , we have

Point estimate for mean -Margin of error = $69,702 (2)

Point estimate for mean +Margin of error = $69,920 (3)

Add (2) and (3), we get

2 (Point estimate for mean) = $139622

Divide both sides by 2, we get

Point estimate for mean=$ 69811

Therefore , the point estimate for mean U.S. household income. = $ 69811

(3,4) and (-5,6) are "coordinate planes".

These appear in algebra and math when you're graphing. These coordinate planes consist of "x" and "y" (x,y). The x's (which are 3 and -5 in your situation) should be graphed accordingly using the x-axis and the y's (which are 4 and 6 in your situation) should be graph accordingly using the y-axis.
