Step-by-step explanation:
4x-9y=-9 1
2x +3y=3 2
1 - 2(2)
4x -9y=-9
(2)* -4x -6y=6
________
0-15y=-3
15y=3
y=3/15
y=1/5
If you have the area of the rectangle, then the equation would be A = W*L
Lets say the area is 15 and the width is 3. You don't know what the length is. Just divide 3 into 15 to get 5. Hope this helps!
So each track practice =3 miles
6miles/3miles= 2
Which gives you an answer of 2 track practices.
This is my very own step-step solution:
Step 1:
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span>
<span> 42*x^5*y^4-((-7*x^3*y)*(b))=0
</span>
Step 2:<span>Equation at the end of step 1 :</span><span>
((42•(x5))•(y4))-((0-(7x3•y))•b) = 0
</span>
Step 3:Pulling out like terms :
<span> 42x5y4 + 7x3yb</span> = <span> 7x3y • (6x2y3 + b)</span>
The correct is: 7x3y • (6x2y3 + b) = 0 <span>
</span>
Quick Side Note:
<span>Binomial can not be factored as the difference of two perfect cubes
</span>
I hope this helps a little!
Hope you have a great day!
