How do you factor 1x^2+9x+2
Answer:
not factorable
Step-by-step explanation:
To factor a trinomial of the type x^2 + ax + b, you need to find two numbers that add to a and multiply to b.
You have 1x^2 + 9x + 2.
In this case, a = 9 and b = 2.
There are no two integers whose sum is 9 and whose product is 2, so this trinomial is not factorable.

23x−15x=x−1 does anybody wanna help I'm so confused???
Step-by-step explanation:
23x - 15x = x - 1. 23 minus 15 equals 8
8x = x - 1. subtract x on both sides
-x. -x
7x = -1. divide 7 on both sides
7. 7
x = -1/7
Directions: if l || m solve for x and y
Answer:
x = 24
y = 15
Step-by-step explanation:
Since, angles (3x - 29)° and (6x - 7)° is a pair of consecutive exterior angles,
Therefore, (3x - 29)° + (6x - 7)° = 180°
9x - 36 = 180
9x = 180 + 36
x = [tex]\frac{216}{9}[/tex]
x = 24
Therefore, (3x - 29)° = 3(24) - 29
= 43°
Since, angles (3x - 29) and (8y + 17) is a linear pair.
(3x - 29)° + (8y + 17)° = 180°
43° + (8y + 17)° = 180°
8y + 60 = 180
8y = 120
y = 15
Therefore, x = 24 and y = 15 will be the answer.

What is the original slope and what is the perpendicular slope?
Answer:
green line:
rise= -6
run= 3
rise/run = slope
therofore the slope = -6/3 = -2
blue line:
rise=3
run=6
rise/run = slope
therofore the slope = 3/6 = 1/2
Answer:
- 2 and [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (0, - 1) ← 2 points on the green line
m = [tex]\frac{-1-5}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
Repeat with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the blue line
m = [tex]\frac{0+3}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Since the product of the slopes = - 2 × [tex]\frac{1}{2}[/tex] = - 1
Then the lines are perpendicular

A brick becomes dislodged from the top of the Empire State Building (at a height of 1250 feet) and falls to the sidewalk below. What is the position formula?
Answer:
Position s(t) = -16t² + 1250 ft
Step-by-step explanation:
Given that:
initial height h₀ = 1250 feet
and suppose the position function is given as:
-16t² + v₀t + h₀
here;
v₀ = initial velocity
t = time
Thus, the position formula can be expressed as:
Position s(t) = -16t² + 1250 ft because v₀ = 0 ft/s and h₀ = 1250 feet
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
Equation:
y=-16x^2+267x+107
Answer:
The rocket will reach the maximum height after 8.34 seconds.
Step-by-step explanation:
We need to take the derivative of the function and set it to 0.
[tex]y' = -32x + 267 = 0\\32x = 267\\x = 8.34[/tex]
The maximum height of the rocket at x = 8.34375 will be 1,220.89.
What are the maxima and minima of a function?For the maximum value of the function if f''(x) < 0 and for the minimum value of the function if f''(x) > 0.
The maximum and minimum value of the function is at f'(x) = 0.
A rocket is sent off from a pinnacle. The level of the rocket, y in feet, is connected with the time after send-off, x like a flash, by the given condition.
The equation is given below.
y = -16x² + 267x + 107
Differentiate the function and put it zero to get the value of time that is 'x' will be given as,
y' = 0
(d/dx)(-16x² + 267x + 107) = 0
-32x + 267 = 0
32x = 267
x = 8.34375
Then the maximum height of the rocket at x = 8.34375 will be given as,
y = -16(8.34375)² + 267(8.34375) + 107
y = -1,113.89 + 2,227.78 + 107
y = 1,220.89
The maximum height of the rocket at x = 8.34375 will be 1,220.89.

What is the relationship between the slopes of two parallel lines?
Answer:In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.
Step-by-step explanation:
The slopes of two parallel lines are always equal.
How to find the slope of a line?The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.
The angle between two parallel lines is zero.
It implies that they form same angle with the x-axis.
Since, the slope of a line is define as the tangent of the angle made by it with x axis.
The slopes of the parallel lines will be equal.
Suppose the slopes of two parallel lines are m₁ and m₂.
Then, it can be written as m₁ = m₂.
Hence, the relationship between the slopes of two parallel lines can be written as m₁ = m₂.
