From the equation, find the axis of symmetry of the parabola. y = 3 x squared minus 12 x + 11 a. x = negative 2 c. x = 1 b. x = 2 d. x = negative 1 Please select the best answer from the choices provided A B C D
Answer:
the axis of symmetry would be: b. x=2
The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = 3x² - 12x + 11
Convert the equation into a vertex form. Then we have
y = 3x² - 12x + 11
y = 3x² - 12x + 12 - 1
y = 3(x² - 4x + 4) - 1
y = 3(x - 2)² - 1
The equation of the axis of symmetry of the parabola is given as,
x - 2 = 0
x = 2
The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.

y-intercept: [tex](0,-\frac{5}{2} )[/tex]
x-intercept: [tex](-2,0)[/tex]
Step-by-step explanation:
Hi there!
Important things to note:
the y-intercept occurs when x=0the x-intercept occurs when y=01) Find the y-intercept
[tex]-5x-4y=10[/tex]
Substitute x with 0
[tex]-5(0)-4y=10\\0-4y=10\\-4y=10[/tex]
Divide both sides by -4
[tex]\frac{-4y}{-4} =\frac{10}{-4} \\y=-\frac{5}{2}[/tex]
Therefore, the y-intercept is [tex]-\frac{5}{2}[/tex]. When written in (x,y) form, x will always be 0 while y is the y-intercept:
[tex](0,-\frac{5}{2} )[/tex]
2) Find the x-intercept
[tex]-5x-4y=10[/tex]
Substitute y with 0
[tex]-5x-4(0)=10\\-5x-0=10\\-5x=10[/tex]
Divide both sides by -5
[tex]-5x=10\\\frac{-5x}{-5}= \frac{10}{-5} \\x=-2[/tex]
Therefore, the x-intercept is -2. When written in (x,y) form, x will always be the x-intercept while y is always 0:
[tex](-2,0)[/tex]

In 2017 the population of Rexburg, Idaho was 28,337 people. The population was expected to grow at a rate of about 1.26% per year. Based on these numbers, what would we predict the population of Rexburg will be in the year 2022?
(Round to the nearest whole number.)
Answer:
30,122
Step-by-step explanation:
This probably isn't the fastest way to solve but....
28,337x1.26%= 357
357x5=1785
28,337+1785=30,122
The 5 came from the # of years the population is increasing
We are required to find the population of Rexburg will be in the year 2022
The population of Rexburg will be in the year 2022 is 30,122 people
Given:
2017 population = 28,337 people
Growth rate per year = 1.26%
let
n = number of years between current and predicted
= 2022 - 2017
n = 5 years
Yearly growth rate = 28,337 × 1.26%
= 28,337 × 0.0126
= 357.0462
Predicted population in 2022 = 2017 population + (357.0462 ×5)
= 28,337 + 1,785.231
= 30,122.231
Approximately, 30,122 people in 2022.
Therefore, the population of Rexburg will be in the year 2022 is 30,122 people

Answer:
y=-32, 0, -16, -4, 16
Step-by-step explanation:
y=4(-6)-8= -32
y=4(2)-8 = 0
y=4(-2)-8 = -16
y=4(1) -8 = -4
y=4(6) -8= 16
For the given equation of the line, the complete table is attached below.
Use the concept of the equation of line defined as:
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.
The given equation of a line is,
y = 4x - x
To complete the table:
Put x = -6 in this equation,
y = (-4)(-6) - 8
y = 16
Put x = 2 in the equation,
y = (-4)(2) - 8
y = -16
Put x = -2 in the equation,
y = (-4)(-2) - 8
y = 0
Put x = 1 in the equation,
y = (-4)(1) - 8
y = -12
Put x = 6 in the equation,
y = (-4)(6) - 8
y = -32

Kyle is buying a $220 bicycle if the bicycle is on sale for 35% off how much will he save
Answer:
$77
Step-by-step explanation:
Okay so first, we know that the bicycle is 220 dollars. So we got to multiply that to the percent. We can't muiltiply it into the percent yet so we turn that percent into 0.35
220 * 0.35
This equals to 77. That's the answer but it's not that simple, cause we aren't finished!
So we know that 35 percent of 220 is 77 dollars. So subtract that to 220!
220 - 77
This is equal to 143. Now how much will he save? He will save 220 - 143, which is 77! That's how we know the answer! I'm sure this is correct, if itsn't please comment! Have a great day!
Answer:
$143
Step-by-step explanation you wanna see how much 35% is out of 220
35% = 0.35
220 * 0.35 = 77 = discount
Now you want to see how much it will be when the discount is applied
220-77 = 143
The bicycle is $143 when discount is applied, you save $77
solve the inequality 3/5x +30>150
Answer:
Step-by-step explanation:
3/5x+30=150
We move all terms to the left:
3/5x+30-(150)=0
Domain of the equation: 5x!=0
x!=0/5
x!=0
x∈R
We add all the numbers together, and all the variables
3/5x-120=0
We multiply all the terms by the denominator
-120*5x+3=0
Wy multiply elements
-600x+3=0
We move all terms containing x to the left, all other terms to the right
-600x=-3
x=-3/-600
x=1/200
Write the point -slope form of the equation of the line (-2,5), slope =6
Answer:
y - 5 = 6(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 6 and (a, b) = (- 2, 5) , then
y - 5 = 6(x - (- 2)) , that is
y - 5 = 6(x + 2)

Step-by-step explanation:
The equation simplifies to ...
ln(-3x·4) = ln(58)
Taking antilogs, the equation becomes ...
