Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Quadratic formula goes as follows [tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex], there is no plus or minus (+/- thingy) sign on here but use both plus and minus on the numerator where I switched the signs.
The equation you give is [tex]3x^2-3x+\frac{3}{4}[/tex], to make it nice, multiply everything by 4 to cancel out the fraction and end up with [tex]12x^2-12x+3[/tex]. So a=12, b=-12, and c=3. Use these values and plug them into quadratic formula.
For the first formula I wrote, [tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex], you get [tex]\frac{-(-12)+\sqrt{(-12)^2-4(12)(3)} }{2(12)}[/tex]= [tex]\frac{1}{2}[/tex].
For the second formula, [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex], you get [tex]\frac{-(-12)-\sqrt{(-12)^2-4(12)(3)} }{2(12)}[/tex]= [tex]\frac{1}{2}[/tex].
Always do quadratic formula for both plus and minus to get both zeros. However, in this case, the answer still remained positive. So the zero of this would be just [tex]\frac{1}{2}[/tex].

brandon sold at least 168 tickets for a carnival. He sold 4 more adult tickets than children tickets.
What is the minimum amount of children's tickets Brandon could have sold?
Answer: 80
Step 1: Find [tex]\frac{1}{2}[/tex] of 168.
168 ÷ 2 = 84
Step 2: Subtract 4, since Brandon sold 4 more adult tickets.
84 - 4 = 80.
Answer = 80

Twelve more than half a number is 10.
Answer:
1/2×+12=10, x=-4
Step-by-step explanation:
Just trust me on this
Answer:
1/2x+12=10
x= -4
Step-by-step explanation:
First subtract 12 from both sides and get 1/2x= -2
Then divide both sides by 1/2
So 2/1 (you flip the fraction to "divide" it which is just multiplying because it is easier) 2/1 times -2 is -4

Answer:
1. 3cm
2. 6m
Step-by-step explanation:
If all angles are right angles, it means that both lengths on the right side add up to the length on the left side.
For the first one, the length on the left is 7cm, and there are two lengths on the right: 4cm and an unknown we can call 'x'.
We know that both of the right lengths add to the left length so we can represent this as so:
4+x=7
To solve for x we can minus 4 from both sides:
x+4-4 = 7-4
x = 7 -4
x = 3cm
We can solve the second one in a similar fashion:
x + 6 = 12
x + 6 - 6 = 12 - 6
x = 12 - 6
x = 6m

How do I do x/3-x/9=6 Pls solve with steps
Answer:
27
Step-by-step explanation:
Hello,
do you agree that
[tex]\dfrac{1}{3}-\dfrac{1}{9}=\dfrac{3-1}{9}=\dfrac{2}{9}[/tex] ?
Then,
we can simplify as below and multiply by 9 both sides and divide by 2
[tex]\dfrac{x}{3}-\dfrac{x}{9}=\dfrac{2x}{9}=6\\\\<=> 2x = 54\\\\<=> x = 54/2= 27[/tex]

19 + x/2 = 4
How do I do this
Answer: x = -30
Steps: 19 + x/2 = 4
Subtract 19 from both sides: 19 + x/2 - 19 = 4 - 19
Simplify: x/2 = 15
Multiply both sides by two: x/2 (2) = -15 (2)
Simplify: x = -30

Functions
We have the function t(x) and some ordered pairs that represent the function:
{(-2,3),(-1,8),(0,-5),(1,-3),(2,-8)}
The ordered pairs have the form ( x , t(x) ). Taking a look at the list of ordered pairs, we find the pair (1,-3), which means

The distribution of speeds along a certain stretch of highway has an mean of 76 mph
and a standard deviation of 7 mph.
What percentage of cars would be traveling slower than 55 mph?
Answer:
0.13%
Step-by-step explanation:
Given that :
Mean = 76mph
Standard deviation = 7 mph
Percentage of cars traveling slower than 55mph
Obtain the Zscore :
X = 55mph
Zscore = (X - mean) / standard deviation
Zscore = (55 - 76) / 7
Zscore = - 3
P(Z < - 3)
From the z table :
P(Z < - 3) = 0.0013
Hence, percentage of cars traveling slower than 55mph is (0.0013 * 100%) = 0.13%

so easy just very confused
Answer:
x=16/3
Step-by-step explanation:
To get the answer you must isolate the x, so first you must add 5 to both sides.
Next you divide by 3 to both sides in order to separate the x from the rest of the equation.
You then get the answer x=16/3
Answer:
x=5.333... or x=16/3
Step-by-step explanation:
3x-5=11
Add 5 to both sides:
3x = 16
Divide both sides by 3:
x=5.333...
The "..." means that the decimal is repeating. So x=5.333... with the number three repeating.
You could also do it this way:
3x-5=11
Add 5 to both sides:
3x = 16
Divide both sides by 3:
3x/3 = 16/3
x=16/3
