A mapping of a set of domain R to another set of domain X is expressed as:
f: X→ R where:
X is the domain
R is the co-domain
For a one-to-one mapping, all the elements of the domain R must have a unique element in the co-domain RFor a one-to-many mapping, an element of the domain R must have more than one element in the co-domain RFor a many-to-many mapping, all elements of the domain R must have a unique element in the co-domain RLearn more here: https://brainly.com/question/24138383

The center of a circle lies on the line y=6x+2 and is tangent to the X axis at (-2,0) what is the equation of the circle in standard form?
Answer:
(x+2)^2 + (y+10)^2 = 100
Step-by-step explanation:
y = 6x + 2
Z(-2,0)
x = -2
y = 6 x (-2) + 2
y = -12 + 2
y = -10
M(-2, -10)
r = 0 - (-10) = 10
(x + 2)^2 + (y + 10)^2 = 100
Answer:
(x + 2)^2 + (y + 10)^2 = 100
Step-by-step explanation:
+2.....+10..100

Ecuación 2:
10x + 20y = 8000
ayudaaa
Answer:
y = 300
x = 200
Step-by-step explanation:
Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:
x + y = 500
10*x + 20*y = 8000
Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.
El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:
x = 500 - y.
Ahora podemos reemplazar eso en la segunda ecuación y obtener:
10*(500 - y) + 20*y = 8000.
Ahora resolvemos esto para y.
5000 - 10*y + 20*y = 8000
10*y = 8000 - 5000 = 3000
y = 3000/10 = 300.
Y sabíamos que:
x = 500 - y = 500 - 300 = 200
Entonces la solución es:
y = 300
x = 200

Answer:
4 < x < 12
Step-by-step explanation:
Given 2 sides, then let x be the third side and
difference of 2 sides < x < sum of 2 sides , that is
8 - 4 < x < 8 + 4
4 < x < 12

What is the y-intercept of the line 3x – 7y = 42?
Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
Subtract 3x on both sides: -7y = 42 - 3xDivide both sides by -7: y = -6 + 3/7xRewrite: y = 3/7x - 6Step 3: Find y-intercept
b = -6
Answer:
(0, -6)

-11 + 9(x + 1) = 4(1 + 3x) - 3
Answer:
x = -1
Step-by-step explanation:
-11 + 9(x+1) = 4(1+3x) - 3
9x + 9 - 11 = 12x + 4 -3
9x - 2 = 12x +1
-2 = 3x + 1
-3 = 3x
x = -1

Levi has a job offer in which he will receive $800 per month plus a commission of 2% of the total price of the cars that he sells. At his current job, he receives $1200 per month plus a commission of 1.5% of his total sales. How much must he sell per month to make the new job a better deal than his current job? Define variables, write a system of equations, and solve.
Answer:
Levi must sell more than 80000 cars per month for the new job to be better than the current job.
Step-by-step explanation:
New Job;
He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.
Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.
Thus;
y = 800 + 0.02x - - - -(eq1)
Current Job:
He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.
Thus;
y = 1200 + 0.015x - - - (eq2)
Substituting 800 + 0.02x for y into eq(2) gives;
800 + 0.02x = 1200 + 0.015x
0.02x - 0.015x = 1200 - 800
0.005x = 400
x = 400/0.005
x = 80000
This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.
