Answer:
a) 0≠ -10
b) x= -3
c)y= 0
Step-by-step explanation:
a) 3-4x=-7-4x

So, this equation has no solution as both sides are not equal.
b) 
Solving:

So, this equation has one solution
c) 7(y-3)=6y-21
Solving:

So, this equation has one solution.
1. Write equation with no solution. 3-4x=-7-4x (check solution of a)
2. Write equation with one solution. 7(y-3)=6y-21 (check solution of c)
3. Write equation with infinite solution. 2x + 3 = x + x + 3
solving:
2x+3=2x+3
2x-2x+3=3
3=3
When both sides are equal, the equation has infinite solutions.

Step-by-step explanation:
The first step is to line it up in the Pythagorean theorem, then you want to move the
to the other side of the equation via subtraction from both sides in order to isolate the
. After that, you'll end up with
then you'll want to square root both sides and end with
.
Answer:
x=2.5&.5
Step-by-step explanation:
The quadratic formula is (-b+or-sqrt(b^2-4ac)/2a
12+or-sqrt((-12^2)-4(4)(5))
12+or-sqrt(144-80)
12+or-sqrt(64)
(12+8)/8 and (12-8)/8
x=2.5 and x=.5
