You have to plug in the values into the equation.
Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.
^ means exponent btw
= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]
Calculate/ simplify
= -[2(36)-6 - (5(36) -9)-4(36)+6]
Multiply all the things in parenthesis
= -[72-6-(171)-144+6]
Add/subtract
= -[-243]
Negative times negative becomes positive therefore, the answer becomes 243
<h2><u>Solve for x</u></h2>
<h3>what are the steps to solve this?</h3><h3>9+6(x-5)=10-3(x-7)</h3>
<u>Step 1:</u> Apply distributive property.
- 9 + 6(x - 5) = 10 - 3(x - 7)
- 9 + 6x - 30 = 10 - 3x + 21
- -21 + 6x = 31 - 3x
<u>Step 2:</u> Combine all like terms.
- -21 + 6x = 31 - 3x
- -21 - 31 = -6x - 3x
- -52 = -9x
<u>Step 3:</u> Divide both sides of the equation by -9 and simplify.
<u>Answer:</u>
- The value of x is <u>52/9</u>.

(1/2)x + 4 is the expression
Answer:
Step-by-step explanation:
the 2nd line can be rewritten as y < x-3
So, any value that is less than both 4x+4 and x-3 will work
Pick any value you want for x, and figure y possibilities
x=0; x-3=-3, 4x+4=4, so y<-3 ... (0,-5) will work
I'm sure you can now come up with other pairs.
