Determine whether each ordered pair is a solution of the system.

Mathematics
1 answer:
Stolb23 [73]3 years ago
8 0

According to the system:

5 – 7x + 2y² = -10

1 – 5x – 2y = -22

______________

a) No ; (4, 6) is not a solution to the

system. This point does not touch either equation.

b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.

Solutions:

( \frac{122 - 3 \sqrt{101}}{25}, \frac{ - 7 +3 \sqrt{101}}{10}) ≈ (3.674, 2.315) \\ ( \frac{122  +  3 \sqrt{101}}{25}, \frac{ - 7  - 3 \sqrt{101}}{10}) ≈ (6.086, -3.715)

x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086

y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715

One kilogram is 2.2 pounds. If i had 1 pound would that be 0.45 kilograms why or why not?
prisoha [69]

Step-by-step explanation:

1 kg = 2.2 pounds

0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations

multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal

1 × 1 = 2.2 × 0.45

1 = 0.99 as you can see this is not an equality therefore the statement is wrong.

Which polynomial represents (6 x 2 −x−9)(4x−7)?
nydimaria [60]

Answer:

The answer to your question is 24x³ - 46x²- 28x + 63

Step-by-step explanation:

Data

               (6x² - x - 9)(4x - 7)

Process

1.- Multiply 4x by the three terms of the first polynomial

           (6x² - x - 9)(4x) = 24x³ - 4x² - 36x

2.- Multiply -7 by the three terms of the first polynomial

           (6x² - x - 9)(-7) = -42x² + 7x + 63

3.- Add both result

           24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63
