What is the y-intercept of the line 3x – 7y = 42?

Answers

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 - 6

Step 3: Find y-intercept

b = -6

Answer:

(0, -6)

Step-by-step explanation:

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.

Answers

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.

Answer: 1

A shape will have a line of symmetry if it can be split in half and look exactly the same except reflected on both sides. For example, a butterfly has one line of symmetry.

This shape only has 1 line of symmetry, because there is only one way we can split it in half and still have it look exactly the same.

You add +3u to both sides to get rid of -3u so 5u+3u=8u
8u=56
Now u want to divide the 8 on both sides of the equation so 56/8=7 and 8/u= would just leave “u”
So u=7

Ecuación 2:
10x + 20y = 8000
ayudaaa

Answers

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

I need help with this problem During the 2004 senatorial campaign in a large southwestern state, illegal immigration was a major issue. One of the candidates argued that illegal immigrants made use of educational and social services without having to pay property taxes.
