Answer:

(g+5)x(g-3)

Step-by-step explanation:

Edmentum/PLATO answer:

Rewrite the expression:

g+1/g^2+5g-3g-15 + g+3/g+5

Factor out g from expression:

g+1/gx(g+5)-3g-15 + g+3/g+5

Factor out g+5:

g+1/(g+5)x(g-3) + g+3/g+5

Least common denominator: (g+5)x(g-3)

What is the solution to the following system of equations:<br><br>7x+2y=24<br>8x+2y=30<br>​
GuDViN [60]

Answer:

7x +2y =24 --------- (i)

8x +2y= 30 ---------(ii)

Subtracting eqn. (i) & (ii)

7x +2y =24

8x +2y= 30

- - -

___________

-x = - 6

Putting the value of x in eqn. (i)

7*6 +2y =24

42 +2y =24

2y =-18

y = - 9

Hence, x=6 and y= - 9

Hope it helps!!

Type the correct answer in each box.
Mariulka [41]

Answer:

(x-5)^2+(y+4)^2=100

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)    

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

r=\sqrt{(2+4)^{2}+(-3-5)^{2}}

r=\sqrt{(6)^{2}+(-8)^{2}}

r=\sqrt{100}\ units

r=10\ units

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center

r is the radius

we have

(h,k)=(5,-4)\\r=10\ units

substitute

(x-5)^2+(y+4)^2=10^2

(x-5)^2+(y+4)^2=100
