We are given with two solutions: y = x2 + 12x + 30 and 8x – y = 10 and is asked to determinte the solutions of the system of equations. We get y in the second eqn which is equal to 8x -10. we substitute this to first eqn resulting to 
8x-10 = x^2 + 12 x + 30. this is a second order equation. x is equal to -2 + 6i and -2 - 6i.

SashulF [63]

Answer:

The correct answer is   104.55

Step-by-step explanation:

From the given information we can write,

Principle amount = 100

<u>To find the amount after 10 years in plan A</u>

Now total = 100

Under plan A increase his account balance by 20.00 per year

Amount increased = 10 *20 = 200

Total = 100 + 200 = 300

<u>To find the amount after 10 years in plan B</u>

Total = 100

Amount after 10 yeras = 100[1 + 15/100]¹⁰

= 100 * 1.15¹⁰ = 100 * 4.04 = 404.55

<u>To find the difference</u>

Difference = 404.55 - 300

= 104.55

The correct answer is   104.55

Sarah will mix yellow paint and red paint in the ratio 2 parts yellow to 3 parts red to create a certain shade of orange paint.
n200080 [17]

Answer:

  • $59.50

Step-by-step explanation:

Given ratio of paints in the mix:

  • yellow : red = 2 : 3

Total volume of paint is 10 quarts, so we have:

  • 2x + 3x = 10
  • 5x = 10
  • x = 2

This is the multiplier, using which we get:

  • Yellow paint = 2*2 = 4 quarts
  • Red paint = 3*2 = 6 quarts

Find the price:

  • 4*5.50 + 6*6.25 = 59.50
