Hi!
<h3>We need to isolate x on one sides, and whatever we do to the equation we have to do on both sides. </h3><h3>Subtract 5 from both sides. </h3>
4x + 5 - 5 = 12 - 5 - 7x
4x = 7 - 7x
<h3>Add 7x to both sides. </h3>
4x + 7x = 7 - 7x + 7x
11x = 7
<h3>Divide by 11 on both sides</h3>
11x/11 = 7/11
<u>x = 7/11</u>
<h2>The answer is x = 7/11</h2>
Hope this helps! :)

Answer:
2%
Step-by-step explanation:
Two percent of the employees have been cited for a safety violation because if you divide 200 and 4 by 2, its 2 out of 100 employees. This can be written as 2/100, .02, or 2%
A correlation coefficient between number of miles driven and number of gallons of gas remaining is most likely to be 0 to -1. Then the correct option is A.
<h3>What is a correlation coefficient?</h3>
A mathematical indicator of the degree of the association seen between fluctuation of 2 factors is the correlation coefficient.
A correlation coefficient between number of miles driven and number of gallons of gas remaining is most likely to be 0 to -1.

Answer:
Step-by-step explanation:
cos^2+sin^2 = 1 ( rule)
cos^4x-cos^2x simplify
- cos^2( -cos^2 +1 ) -cos^2 common
or -cos^2 ( 1-cos^2)
since cos^2 + sin^2 = 1
substitute : -cos^2 ( sin^2 )
substitute : -(1-sin^2 ) ( sin^2)
multiply : -sin^2 + sin^4 or sin^4 - sin^2
it is verified that sin^4 -sin^2= cos^4-cos^2
