through: (-2,-4), perp. to y= -1/2x
Answer:
y = 2x
Step-by-step explanation:
The slopes of two perpendicular lines are negative reciprocals of each other. So the slope is 2
m = 2, y = -4, x = -2
y = mx + b
-4 = 2(-2) + b
b = -4 + 4
b = 0

On a map , 1 inch represents 50 miles. You measure the distance on the map between two towns as 3 1 2 inches. How many miles apart are the towns?
The towns are 15600 miles apart.
WHAT IS MAP SCALE ?The term "map scale" refers to the proportion between a distance on a map and its corresponding distance on the ground. Lets see an example like, On a map with a scale of 1:100,000, one kilometer on the ground is equivalent to one centimeter. The scale of a map refers to the proportion between a distance on a map and its actual distance on the ground. This simple concept is complicated by the fact that scale must vary across a map due to the curvature of the Earth's surface. The concept of size is now important in two different ways as a result of this development.
The size of the producing globe is compared to the size of the Earth in the first technique. a theoretical globe known as the generating globe, upon which the map is projected and the Earth is compressed. The ratio of the size of the Earth to that of the generating globe is known as the nominal scale, also known as the major scale or representative fraction.
CALCULATION∵ 1 inch = 50 miles on the map
∴ 312 inches = 312 * 50 = 15600 miles .

2(3b - 2) = 2(2b + 12)
One way to solve is to follow these steps
2(3b - 2) = 2(2b + 12)
2*3b - 2*2 = 2*2b + 2*12
6b - 4 = 4b + 24
6b-4b = 24+4
2b = 28
b = 28/2
b = 14
Final answer: b = 14The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 310, 304,298,... 310,304,298,... \text{Find the 47th term.} Find the 47th term.
The 47th term in the given arithmetic sequence is 34.
Given,
The arithmetic sequence = 310, 304, 298,......
First term of the sequence, t₁ = 310
Common difference of the sequence, d = t₂ - t₁ = 304 - 310 = -6
nth term of an arithmetic sequence, tₙ = t₁ + ( n - 1) d
We have to find the 47th term of the arithmetic sequence.
That is, n = 47
So,
t₄₇ = 310 + (47 - 1) -6
t₄₇ = 310 + (46 x (-6) )
t₄₇ = 310 - 276
t₄₇ = 34
Therefore, the 47th term in the given arithmetic sequence is 34.

the required simplified value of given expression 4x = 12x + 32 is x = -4 (hence proved).
Given that,
An expression is given 4x = 12x + 32,
We have to prove x = -4 as of simplified solution.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
4x = 12x + 32
Taking 12x to the left side of the equal sign and it becomes -12x

Answer: x=21, y=8
Step-by-step explanation:
18y+5=10x-61 ==> 18y+5 and 10x-61 are congruent angle, so they're equal
x+10+10x-61=180 ==> x+10 and 10x-61 are supplementary angles since they're on a straight line(a straight line measures 180 degrees and is called a straight angle), so they add up to 180 degrees.
x+10x+10-61=180
11x-51=180
11x=231
x=21
18y+5=10(21)-61
18y+5=210-61
18y+5=149

Answer: 56.25 of 70% and 93.75pints of 90%
Step-by-step explanation: First find the ratios. One juice is 70% and the other is 95%. Your goal is 85%. This is 15% from 70 and 10% from 95. This means you need (15)/(15+10) of 95, which is 3/5 of all the juice to be 95. This means you will need more of the 95% juice, which makes sense because 85 is closer to 95. So 3:5 and total 150=56.25 of 70% and 93.75pints of 90%

One number is six less than three times another number. If the sum of the numbers is 38, find the numbers
Answer:
consider the two number as x and y
first given condition
x-6 = 3y
i.e. x= 3y + 6 eqn 1
second given condition
x+ y = 38
i.e. x= 38-y eqn 2
solving eqn 1 and 2
3y + 6 = 38-y
3y + y = 38-6
4y = 32
y = 8
substituting the value of y in eqn 2
x = 38 - y
x= 38-8
x= 30
hence the required numbers are 8 and 30
Convert the polar equation to rectangular form and identify the graph. Support your answer by sketching the graph. Show and explain your work.
The polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).
How to transform a polar expression into its rectangular formPolar and rectangular forms are related by this relation: (x, y) → (r · cos θ, r · sin θ), where r is the radial distance with respect to the origin and θ is the angle in standard position. We can use this fact to change the given expression into its rectangular form:
r = - 4 · (x / r)
r² = - 4 · x
x² + y² = - 4 · x
y² = - (x² + 4 · x)
y² - 4 = - (x² + 4 · x + 4)
y² - 4 = - (x + 2)²
(x + 2)² + y² = 4
(x + 2)² + y² = 2²
In a nutshell, the polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).

f(x)=x+1 is a formula for a function f(x) that has f(9)=10
What is a simple definition for function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input
a constant function is a function whose (output) value is the same for every input value. For example, the function y(x) = 10 is a constant function because the value of y(x) is 10 regardless of the input value x
if we take f(x)= x+1
then put x=9 we get f(9)= 10
Hence , f(x)=x+1 is a formula for a function f(x) that has f(9)=10

The term (- x² + 2x + 1 ) must be subtracted from (x² + 2x - 3) to get
(2x² - 4).
Here,
We have to find the number which must be subtracted from x² + 2x - 3 to get 2x² - 4.
What is Number system?
A system of writing to express the number is called number system.
Now,
Let 'a' must be subtracted from x² + 2x - 3 to get 2x² - 4.
It can be written as;
(x² + 2x - 3) - a = 2x² - 4
a = (x² + 2x - 3) - (2x² - 4)
a = x² + 2x - 3 - 2x² + 4
a = - x² + 2x + 1
Therefore, The term (- x² + 2x + 1 ) must be subtracted from x² + 2x - 3 to get 2x² - 4.
