Solve the system of equations and choose the correct ordered pair. 3x-4y=26 2x+8y=-36 a.(2,-5) b.(2,5) c.(6,2) d.(6,-2)

3x-4y=26

2x+8y=-36

We will solve this system with gaus algorithm

We multiply first equation with number 2 and we get

6x-8y=52 => we add second equation to this and we get

8x=16 => x=2 => we replace x=2 in first equation and we get

3*2-4y=26 => 6-4y=26 => -4y=20 => y=-5

The correct answer is A.

Good luck!!!

So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

Next, add the two equations together to get . From here you can solve for x.

For this equation, just divide both sides by 8 and your first answer will be

Now that we have the value of x, substitute it into either equation to solve for y:

In short, the solution is (2,-5), or A.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
