what is the perpendicular and parallel lines of y= -2 -4x
y=1/4x-2 is a perpendicular line and y=-4x+3 is a parallel line.
The equation y= -2 -4x in the form of slope intercept form y=mx+b is y=-4x-2.
Where m represents the slope and y intercept is -2.
The slope of a line perpendicular to another line is the negative reciprocal of the slope of the given line.
The negative reciprocal of -4 is 1/4.
Therefore, the slope of the perpendicular line is 1/4.
The perpendicular line is y=1/4x-2.
We know that the parallel lines have same slope.
y=-4x+3
Hence, y=1/4x-2 is a perpendicular line and y=-4x+3 is a parallel line.

The price of apples can be determined by the equation P=0.23n, where P is the price and n is the number of apples. What is the constant of proportionality (unit rate)
Answer:
The constant of proportionality(Unit rate) is 0.23
Step-by-step explanation:
Given equation is:
\(P = 0.23n\)
Here
P is the price and n is the number of apples
The price is usually directly proportional to quantity so the relationship can be written as:
P ∝ n
Removing the proportionality symbol, we get
P = kn
Comparing the given equation with this equation we get
k = 0.23
Hence,
The constant of proportionality(Unit rate) is 0.23

weighs 2 pounds. The math book is 4 times the weight of the library book, and his science
book is 2 times the weight of the math book. How much does his book bag weigh with all
these books? What is the heaviest book in his book bag?
Answer:
1) 30 pounds is the weight of the bag all together
2) science book is the heaviest book
Step-by-step explanation:

You have a piggy bank containing a total of 66 coins in dimes and quarters. If the piggy bank contains $10.20, how many dimes are there in the piggy bank?
I have 42 dimes in my piggy bank according to the given condition of 66 coins and amount $10.20 and used the system of equation as well as substitution method.
What is system of equation?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations.
What is substitution method?Finding the value of any variable from one equation in terms of another variable is the first step in the substitution method. For instance, if there are two equations, x+y=7 and x-y=8, we can deduce that x=7-y from the first equation. Applying the substitution method begins with this.
Here,
x+y=66 ......(1)
1 dime values 10 cents.
1 quarter values 25 cents.
10x+25y=1020 ........(2)
x=66-y
10(66-y)+25y=1020
660-10y+25y=1020
15y=360
y=360/15
y=24
x=66-24
x=42
I used the system of equations and the substitution method to determine that I have 42 dime coins in my piggy bank in accordance with the requirement of 66 coins totaling $10.20.

Determine the equation of the circle graphed below.
Answer:
\((x - 6)^2 + (y - 2)^2 = 4\)
Step-by-step explanation:
Required
The equation of the circle
The equation of a circle is:
\((x - h)^2 + (y - k)^2 = r^2\)
Where:
\(Center = (h,k)\)
\(radius \to r\)
From the graph, we have
\((h,k) = (6,2)\)
\(r = 2\)
So:
\((x - h)^2 + (y - k)^2 = r^2\) becomes
\((x - 6)^2 + (y - 2)^2 = 2^2\)
\((x - 6)^2 + (y - 2)^2 = 4\)

A curve, described by x2 + y2 + 6y = 0, has a point A at (−3, −3) on the curve.
Part A: What are the polar coordinates of A? Give an exact answer.
Part B: What is the polar form of the equation? What type of polar curve is this?
Part C: What is the directed distance when theta equals 4 pi over 3 question mark Give an exact answer.
a) The polar coordinates of point A are (√(18), π/4).
b) The curve is a circle centered at the origin with radius 6.
c) The directed distance is the value of r, which is 6 √(3).
To find the polar coordinates of point A on the curve, we need to convert the point from Cartesian to polar coordinates. The conversion formula is:
r = √(x² + y²)
θ = arctan(y/x)
Using the values of point A, we have:
r = √((-3)² + (-3)²) = √(18)
θ = arctan((-3)/(-3)) = arctan(1) = π/4
To find the polar form of the equation x² + y² + 6y = 0, we need to convert it from Cartesian to polar coordinates. The conversion formulae are:
x = r cos(θ)
y = r sin(θ)
Using these formulae, we can rewrite the equation as:
r² cos²(θ) + r² sin²(θ) + 6r sin(θ) = 0
Simplifying this equation, we get:
r = -6 sin(θ) / (1 - cos²(θ))
To find the directed distance when θ equals 4 π over 3, we need to substitute this value of θ into the polar equation we found in Part B. Doing so, we get:
r = -6 sin(4 π/3) / (1 - cos²(4 π/3))
r = -6(-√(3)/2) / (1 - (-1/2)²)
r = 6 √(3)

A Diamond ring that normally sells for $1275 is on sale for $1020. A ruby ring that sells for $290 is on sale for $203. What is the percent markdown for the diamond rind and what is the percent markdown for the ruby ring?
Answer:
20%, 30%
Step-by-step explanation:
A diamond ring that normally sells for $1275 is now being sold at $1020
The percent mark down of the diamond ring can be calculated as follows
= 1275-1020
= 255
= 255/1275 ×100
= 0.2 ×100
= 20%
A ruby ring that sells for $290 is now being sold at $203
= 290-203
= 87
= 87/290 ×100
= 0.3×100
= 30%
Hence the percent mark down for the diamond ring and ruby ring is 20% and 30% respectively

Answer:
L = 9.49 units
Step-by-step explanation:
From the 1st point to the 2nd, x changes by 12; from the 1st to the 2nd, y changes (increases) by 6. These results (12 and 6) represent the leg length of a right triangle whose diagonal length we wish to calculate using the Pythagorean Theorem:
12^2 = 144 and 6^2 = 36.
Combining these results in the length of the diagonal:
L = √(144 + 36) = √180 = 13.42 units using the Pythagorean Theorem
Rounding off, we get L = 9.49 units
Write a sine function with an amplitude of 5, a period of
Pi/8,and a midline at y = 7.
f(x) = 4sin(8x) + 5
f(x) = 5sin(16)+7
f(x) = 5sin(16x) + 4
f(x) = 4sin(8x) + 7
Answer:
\(\textsf{B)} \quad f(x) = 5 \sin (16x) + 7}\)
Step-by-step explanation:
The sine function is periodic, meaning it repeats forever.
Standard form of a sine function\(\boxed{f(x) = A \sin (B(x + C)) + D}\)
where:
A is the amplitude (height from the midline to the peak).2π/B is the period (horizontal distance between consecutive peaks).C is the phase shift (horizontal shift - positive is to the left).D is the vertical shift (y = D is the midline).Given values:
Amplitude, A = 5Period, 2π/B = π/8Phase shift, C = 0Vertical shift, D = 7Calculate the value of B:
\(\dfrac{2\pi}{B}=\dfrac{\pi}{8}\implies 16\pi=B\pi\implies B=16\)
Substitute the values of A, B C and D into the standard formula:
\(f(x) = 5 \sin (16(x + 0)) + 7\)
\(f(x) = 5 \sin (16x) + 7\)
Therefore, the sine function with an amplitude of 5, a period of π/8, and a midline at y = 7 is:
\(\Large\boxed{\boxed{f(x) = 5 \sin (16x) + 7}}\)
