F(x)=3x^2+6x-8
Formula: a=-b/2(a)
a=-6/2(3)=-3
I guess the answer is d)
Answer:
1. 244
2. 122

Answer:
B. Negative two-fifths (-2/5)
Step-by-step explanation:
1. Change the second number into a fraction if it isn't already.
2. Find the reciprocal of the divisor, or second fraction.
3. Multiply the numerators together.
4. Multiply the denominators together.
5. Simplify the answer if possible.
6. Determine if the answer is positive or negative using the sign rules.
Show your work:
-4/5 divided by 2/1
-4/5 divided 1/2
-4 * 1 = -4
5 * 2 = 10
Simplify:
-4/10 = -2/5
1/2(x - 3) = 2/3(x - 8)
<em><u>Distributive property on both sides.</u></em>
0.5x - 1.5 = 0.7x -5.3
<em><u>Add 5.3 to both sides.</u></em>
0.5x + 3.8 = 0.7x
<em><u>Subtract 0.5x from both sides.</u></em>
3.8 = 0.2x
<em><u>Multiply both sides by 5.</u></em>
x = 19 (This is your answer.)
