12 + 0.35X = 20.05
12 + 0.35X - 12 = 20.05 - 12
0.35X = 8.05
0.35X/0.35 = 8.05/0.35
X = 23
Hope this helps!!
10/15 is the correct answer
5 and 7 add to make 12 and multiply to make 35 so those are the numbers that will be used:
(x+5)(x+7)
Hope this helps :)

Answer:</h2>
We need to solve both for y.
<u>#9:</u>
<u />
<u />
<u>#10:</u>
<u />![y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11](https://tex.z-dn.net/?f=y%20-%201%20%3D%20-4%5Bx%20-%20%28-3%29%5D%5C%5C%5C%5Cy%20-%201%20%3D%20-4%28x%20%2B%203%29%5C%5C%5C%5Cy%20-%201%20%3D%20-4x%20-%2012%5C%5C%5C%5Cy%20%3D%20-4x%20-%2011)
<u />
The resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
<h3>Quadratic equations</h3>
Quadratic equations are equations that has a leading degree of 2. Given the following system of equations
y=2x
y=x^2+2
Equate to have:
2x = x^2+ 2
Equate to zero
x^2 - 2x +2 = 0
Since the resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
