Answer:

x=-8,8

Step-by-step explanation:

\frac{x^2}{2} -32=0\\multiply ~by~2\\x^2-64=0\\x^2-8^2=0\\(x+8)(x-8)=0\\ether~ x=-8\\or~x-8=0\\x=8\\x=-8,8x=-8

missing  either x+8=0

x=-8

the altitude of A (in feet) of a plane T minutes after liftoff is given by a=3400t + 600. How many minutes after liftoff is the
____ [38]

If our equation is a = 3400t + 600, and we have a target altitude of 21,000, we just need to plug that in for a.

21,000 = 3,400t + 600. Now subtract 600 from both sides.

20,400 = 3,400t. now divide both sides by 3,400.

6 = t.

We get that our answer is at 6 minutes we get an altitude of 21,000 feet!

2. Follow the process used to simplify the expression. Tell if it was done correctly. If not, explain and correct the error by s
wariber [46]

Answer:

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

the correct answer is 12k-8

Step-by-step explanation:

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

Correcting the error:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8

So, the correct answer is 12k-8

Can you please help thanks ​

The two best deals would be buy two get two free and the 1/2 off because both would equal 50% off the total price of buying 4 wheels.

This is better than the alternative of only 45% off.

I dont understand what I'm supposed to do
marissa [1.9K]

Your suppose to take the order pair you got and subsitute it in both of the equations. The chart has the y and x on one side and a number on the other. Treat it like an algebraic equation and try to see if when you subsitute the x and y with the order pair given you get the number on the other side of the equation. For example x + 3y = 6 once subsituted with the order pair looks like 3 + 3(1) = 6. From there you do one step at time until finally you get 6 = 6 which tells you that (3,1) is a solution for this equation. Now you have to find out if the ordered pair works for both of the equations not just one since it said "given system". Hope I explained it clearly enough :)
