Answer:
x = -3/2
Step-by-step explanation:
4x² + 12x + 9 = 0
Use AC method to factor, or recognize the perfect square.
(2x + 3)² = 0
2x + 3 = 0
x = -3/2

Answer:
x=3+3/4
Step-by-step explanation:
1+4x/6=3.5
We move all terms to the left:
1+4x/6-(3.5)=0
We add all the numbers together, and all the variables
4x/6-2.5=0
We multiply all the terms by the denominator
4x-(2.5)*6=0
We add all the numbers together, and all the variables
4x-15=0
We move all terms containing x to the left, all other terms to the right
4x=15
x=15/4
x=3+3/4
Answer:
y = -19x + 14
Step-by-step explanation:
For each increase of x by 1, y decreases by 19, giving us -19x. When x = 0, y = 14, therefore, y = -19x + 14
Distribute the 3.
3*x + 3*4
3x + 12
Hope this helps :)
