6b + 5
Step-by-step explanation:
We begin by expounding the equation so as to remove the brackets;
2(a -3) + 4b - 2(a -b -3) + 5
2a – 6 + 4b - 2a + 2b + 6 + 5
Then we put the like terms together;
2a – 2a + 4b + 2b – 6 + 6 + 5
Now when the equation is simplified will look like this;
= 6b + 5

Answer: D) It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.
Step-by-step explanation:
slope is y2-y1/x2-x1
20-10/7-7
10/0
denominator can't be 0
The answer is $6.80 because you need to divide both by 12 then times by 10
<h3>I'll teach you how to solve 4x^2-25<0</h3>
-------------------------------------------------
4x^2-25<0
Add 25 to both sides:
4x^2-25+25 < 0+25
Simplify:
4x^2 < 25
Divide both sides by 4:
4x^2/4 < 25/4
Simplify:
x^2 < 25/4
whole sqrt -25/4 < x < whole sqrt 25/4
whole sqrt 25/4= 5/2
-5/2 < x < 5/2
Your Answer Is -5/2 < x < 5/2
