Answer:

I think the answer is "Determine the shaded area for each line", because this is an example of an equation not an inequality. You can tell this is an equation because of the equal sign.

Inequalities are the problems in which you have to worry about shading, not equations. Inequalities can be identified by having either a greater than sign, a less than sign, a greater than-or-equal-to sign, or a less than-or-equal-to sign.

SCORPION-xisa [38]

Answer:

a) 0≠ -10

b) x= -3

c)y= 0

Step-by-step explanation:

a) 3-4x=-7-4x

$3-4x=-7-4x\\Adding \ 4x \ on \ both \ sides\\3-4x+4x=-7-4x+4x\\3-0=-7\\Adding \ -3\\3-0-3=-7-3\\0\neq -10$

So, this equation has no solution as both sides are not equal.

b) $15-2x=-7x$

Solving:

$15-2x=-7x\\Adding \ 2x \ on \ both \ sides\\15-2x+2x=-7x+2x\\15=-5x\\Divide \ both \ sides \ by -5\\x=-3$

So, this equation has one solution

c) 7(y-3)=6y-21

Solving:

$7(y-3)=6y-21\\7y-21=6y-21\\Adding \ -6y \ on \ both \ sides\\7y-21-6y=6y-21-6y\\y=-21+21\\y=0$

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 $6^{2}$ to the other side of the equation via subtraction from both sides in order to isolate the $x^2$ . After that, you'll end up with $x^{2} =64$ then you'll want to square root both sides and end with $x=8$ .
