a) 6x - 5y = 10x + 7 SOLVING FOR X:
6x-5y=10x+7
−5y=10x+7−6x
−5y=4x+7
−5y−7=4x next divide both sides by four and switch sides
![\frac{-5y-7}{4} =x](https://tex.z-dn.net/?f=%5Cfrac%7B-5y-7%7D%7B4%7D%20%3Dx)
![x=\frac{-5y-7}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-5y-7%7D%7B4%7D)
a) 6x - 5y = 10x + 7 SOLVING FOR Y:
6x-5y=10x+7
−5y=10x+7−6x then simplify
−5y=4x+7, now divide both sides by negative five
![y=\frac{4x+7}{5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4x%2B7%7D%7B5%7D)
b) -4 +(-3) -(-9)
-4+(-3)-(-9) Remove parentheses and simplify.
−4−3+9=−7+9=2
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Answer:
b im positive it B but if im wrong message me
A gardener has 10 pounds of soil. Now he 5/8 of that soil for his garden. Let's solve how many pounds of soil did he used and how many pounds is left.
=> 5/8
=> 10 lbs / 8 = 1.25 lbs
=> 1.25 lbs * 5 = 6.25 lbs.
He used 6.25 lbs of soil for his garden and has 3.75 lbs of soil left.
Answer:
(x+5)²+(y-4)²=17
Step-by-step explanation:
I think it's safe to assume that the (-5,4) coordinate is in the center
To find the x and y coordinate just flip the signs
which means it would look like
(x+5)²+(y-4)²=?
the question mark is equal to the raidus squared
to find the radius use the distance formula
√((-4+5)²+(8-4)²)= 4.123106
square this to get 17
the final answer is then
(x+5)²+(y-4)²=17
