OK first convert one of the equations into Y=MX+b form

Y-2x = 3
Add 2X

Y = 2x +3
Now substitute this equation in the other one.
So it would be

3X - 2Y = 5

3X-2(2x+3) = 5

Now solve for y

3X - 4X - 6 = 5

-1X - 6 = 5

Add 6

-1X = 11

X = -11

Now substitute this into one of the equations

Y - 2X = 3

Y -2(-11) = 3

Y +22 = 3

y = 3-22

y = -19

Does the equation have a max or min
Yakvenalex [24]

Answer:

Min

Step-by-step explanation:

To check if it has a max or min, you must reference the a value. The a value in this case is 2, and that is positive. Positive parabolas point up, so they can only have a minimum point.

Use estimation to help you choose the correct answer.<br><br> 0.945 x 7.6 =
hoa [83]

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.


What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly


0.945 is almost 1.


Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.
