Can someone please tell me what I'm doing wrong? I think I know how to do quadratic formula, and I know all the steps, but the l

Nata [24]

Okay, so first you set equal to 0:
$6-6x^{2}=3x\\-6x^{2}-3x+6=0$

Next simplify the equation so that the leading coefficient is positive:
$\frac{-6x^{2}-3x+6}{-3}=\frac{0}{3}\\2x^{2}+x-2=0$

Looking at the quadratic equation you can't easily simplify it, so plug it into the quadratic equation and simplify:
$x=\frac{-b\ -+\ \sqrt{b^{2}-4ac}}{2a}\\\\x=\frac{-(1)\ -+\ \sqrt{(1)^{2}-4(2)(-2)}}{2(2)}\\\\x=\frac{-1\ -+\ \sqrt{1+16}}{4}\\\\x=\frac{-1\ -+\ \sqrt{17}}{4}*\frac{-1}{-1}\\\\x=\frac{1\ -+\ \sqrt{17}}{-4},\ or\ B.$

I noticed a couple mistakes in your work, so if you want me to I can explain them in the comments section :)

4 1/8 --> 4 3/24 --> 99/24

1 1/4 --> 1 6/24 --> 30/24

About how much more grape juice and orange juice is used in the punch

80/24+156/24 = 59/6 or 236/24

99/24+30/24= 43/8 or 129/24

236/24-129/24= 107/24 cups OR 4.458 cups OR 4 11/24 cups

About how much more grape juice than orange juice is used in the punch

3 1/3 --> 3 8/24 --> 80/24

6 1/2 --> 6 12/24 --> 156/24

approximately -3

Which exponential equation is equivalent to this logarithmic equation log x5 + log x12 =7

trapecia [35]

Answer:

x⁷ = 60

Step-by-step explanation:

Given :-

log x⁵ + log x ¹² = 7 .

To Find :-

The expotential equation .

Solution :-

Given logarithmic equation is ,

⇒ log x⁵ + log x ¹² = 7

⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]

⇒log x ⁶⁰ = 7

In expotential form we can write it as ,

⇒ x⁷ = 60
