Y = x^2 - 6y + 8

y = (x - 3)^2 - 9 + 8

y = (x -3 )^2 - 1

vertex is at ( 3, -1)

<u><em>x=8 is the correct answer.</em></u> First you had to subtract by 5 from both sides of equation, and it gave us, $\frac{x}{4}+5-5=7-5$ . And then simplify, and it gave us, $\frac{x}{4}=2$ . Then you can multiply by 4 from both sides of equation, and it gave us, $\frac{4x}{4}=2*4$ . And finally simplify, and it gave us the answer is 2*4=8, or <u><em>x=8 is the correct answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Say a certain service industry has 78.9 thousand jobs in 2003, but expects to increase at an average annual rate of 2.65 thousan

Alex_Xolod [135]

Answer:

33%

Step-by-step explanation:

In 2003, there were 78.9 thousand jobs in the industry and it increases annually by 2.65 thousand jobs from 2003 to 2013.

Hence, from 2003 to 2013, i.e. 10 years the jobs have increased by (2.65×10) = 26.5 thousand.

Therefore, the percent increase in jobs in the industry from 2003 to 2013 is given by $\frac{26.5*100}{78.9} = 33.6$ % ≈ 33%. (Answer)
