Answer:
There is 1 solution (1,0)
Step-by-step explanation:
y = 3.5x − 3.5
y = −3.5x + 3.5
Add this system of equations together
y = 3.5x − 3.5
y = −3.5x + 3.5
-----------------------
2y = 0
y = 0
Substitute back in
0 = 3.5x - 3.5
Add 3.5 to each side
3.5 = 3.5x
Divide by 3.5
3.5/3.5 = 3.5x/3.5
1=x
There is 1 solution (1,0)
Answer:
4x² + 12x + 9
Step-by-step explanation:
<h3>
Using identity: </h3>
(a +b)² = a² + 2ab + b²
Here, a = 2x & b = 3
(2x +3 )² = (2x)² + 2*2x*3 + 3²
= (2x*2x) + 12x + 3*3
= 4x² + 12x + 9
