Write the equation of a line perpendicular to y=-12x+2 going
through (0, -1)
[tex]\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]
First, let's take a look at our provided information:-
A line [tex]\text{y=-12x+2}[/tex]A point (0, -1)The line [tex]\text{y=-12x+2}[/tex] is perpendicular to the line that goes through (0, -1)If two lines are perpendicular to each other, their slopes are opposite reciprocals of each other.
So we take the slope of the given line, which is -12, change its sign from minus to plus:-
[tex]\Large\textit{12}[/tex]
And now, We flip the number over:-
[tex]\Large\text{$\displaystyle\frac{1}{12}$}[/tex]
Now that we've found the slope of the line, let's find its equation.
The first step is to write it in point-slope form as follows:-
[tex]\longmapsto\sf{y-y_1=m(x-x_1)}[/tex]
Replace letters with numbers,
[tex]\longmapsto\sf{y-(-1)=\displaystyle\frac{1}{12}(x-0)}[/tex]
On simplification,
[tex]\longmapsto\sf{y+1=\displaystyle\frac{1}{12} (x-0)}[/tex]
On further simplification,
[tex]\longmapsto\sf{y+1=\displaystyle\frac{1}{12} x}[/tex]
Subtracting 1 on both sides,
[tex]\longmapsto\sf{y=\displaystyle\frac{1}{12} x-1}[/tex]

distance between points (-4,4) and (4,-2)
Answer:
10 units
Step-by-step explanation:
calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 4, 4 ) and (x₂, y₂ ) = (4, - 2 )
d = [tex]\sqrt{(4-(-4))^2+(-2-4)^2}[/tex]
= [tex]\sqrt{(4+4)^2+(-6)^2}[/tex]
= [tex]\sqrt{8^2+36}[/tex]
= [tex]\sqrt{64+36}[/tex]

Show that (x − 9)(x − 1) ≡ x^2 − 10x + 9
We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓

Consider the quadratic equation x2 10x 27 = 0. completing the square leads to the equivalent equation (x )2 = .
The solution to the given quadratic expression using the completing the square is x = ±√-2 -5
Completing the square methodThis is a method of factoring quadratic expression. Given the quadratic function.
x^2 + 10x + 27 = 0
Subtract 27 from both sides
x^2 + 10x = -27
Complete the square
x^2 +10x +5^2 = -27 + 25
(x+5)² = -2
x +5 = ±√-2
x = ±√-2 -5
Hence the solution to the given quadratic expression using the completing the square is x = ±√-2 -5

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. David invested $230 in a savings account that offers a 3% return on the investment. The value of David's investment will be at least $415 after a period of years. Hint: Use the formula A = P(1 + r)t, where A is the amount after t years, P is the amount invested, r is the rate of interest, and t is the time period. Use a calculator to compute the answer, and round it off to the nearest year.
The value of David's investment will be at least $415 after a period of 20 years
Compound interestThe formula for calculating the compound interest is expressed as:
A = p(1+r)^t
Given the following parameters
A = $415P = $230r = 3% = 0.03Substitute
415 = 230(1+0.03)^t
415/230 = 1.03^t
1.8043 = 1.03^t
t = ln(1.8043)/ln1.03
t = 20 years
The value of David's investment will be at least $415 after a period of 20 years
