1) 2x + 3y = 12 -> 3y = -2x +12 -> y = -2/3x + 4
2) 4y - 7x = 16 -> 4y = 7x + 16 -> y = 7/4x + 4

I need help someone help
Alex17521 [72]

D is the answer

because you are doing y=2(x+3)^2 - 5

First, do exponents

(x+3)(x+3) = x^2 + 6x + 9

now Multiply your answer by 2

2(x^2 +6x + 9) = 2x^2 + 12x + 18

Then, Subtract 5 from 18

2x^2 +12x + 18-5 = 2x^2 + 12x + 13

bringing you to answer D

Find conditions on the slope of a line through (9, 4) such that the x-intercept is negative and the slope is greater than its y-
Vilka [71]

Answer:

9/5 < m < 9/4

Step-by-step explanation:

The conditions are:

  • The line passes through (9,4)
  • x-intercept is negative
  • The slope (m) is greater than its y-intercept

If we take a point like (-1,0)

Slope (m) = change in y ÷ change in x = \frac{0 - 9}{-1 - 4}  = \frac{-9}{-5} = 9/5

This point satisfies the conditions above since;

  1. The line passes through points (9,0) and (-1,0)
  2. The x-intercept is negative i.e -1
  3. The y-intercept is 0 and the slope which equals 9/5 is greater than 0

From the choices given;

we can say that:

m > 9/5 and m < 9/4

And can be expressed as;

9/5 < m < 9/4

I need help with Estimated Variable and Fixed Cost. How do I figure that out in the problem attached?
saul85 [17]

The fixed and variable costs of the given table of production costs are respectively; $161280 and $42

<h3>How to calculate fixed and variable costs?</h3>

Variable costs are costs that vary/change depending on the company’s volume of production while fixed costs are costs that do not change in relation to volume of production.

Fixed costs = Production Cost + Selling expenses + Administrative Expenses

Fixed Cost = $103200 + $21500 + $7300 + $1600 + $1800 + $21000 + $2600 + $2280 = $161280

Variable cost = $15 + $10 + $8 + $3 + $3 + $1 + $2

Variable cost = $42
