Mathematics

Answer:

(5,-1)

Step-by-step explanation:

4x+3y=17

3x+2y=13

So elimination sounds fun but we will have to do manipulation:

Multiply top equation by 2 and bottom equation by 3. This will cause the second term in both by 6y which means we would be setup for elimination.

8x+6y=34

9x+6y=39

--------------------now subtract the equations

-x+0=-5

So x=5

Now plug it into either question (no matter which-pick and choose)

I will go with the second original 3x+2y=13

So if x=5 we have 15+2y=13

Subtract 15 on both sides:        2y=-2

Now divide both sides by 2:      y=-1

Answer (5,-1)

Can anyone be nice and help a girl out. please i need help.
Nuetrik [128]

Answer:

Step-by-step explanation:

So when we solve the inequality:

2(x - 2) >_ 2

x - 2 >_  1 (divided 2 from both sides)

x >_ 3 (added 2 to both sides)

So with our final equation, we can work out that the answer is b, but d is also correct so I'm assuming that the inequality needs to be represented on a number line as hey usually are.

Hope this helps,

A farmer Has 900 yards of fencing to enclose a rectangular pasture for her goats. Since one side of the pasture borders a river,
horsena [70]

Answer:

Length, l=450 yards

Width, b=225 yards

Step-by-step explanation:

Let the long side be x and since the length is twice the width, then the width is half of that length hence 0.5x. Since we only have three parts to fence as one long side doesn't require fencing, then the perimeter will be given by x+0.5x+0.5x=2x=900 yards

X=900/2=450 yards for long side.

The short side is 0.5x hence 0.5*450=225 yards

In conclusion, the long side is 450 yards while short side is 225 yards.
