No solution of the system of equations y = -2x + 5 and -5y = 10x + 20 ⇒ 2nd answer

Step-by-step explanation:

Let us revise the types of solutions of a system of linear equations

  • One solution
  • No solution when the coefficients of x and y in the two equations are equal and the numerical terms are different
  • Infinitely many solutions when the coefficients of x , y and the numerical terms are equal in the two equations

∵ y = -2x + 5

- Add 2x to both sides

∴ 2x + y = 5 ⇒ (1)

∵ -5y = 10x + 20

- Subtract 10x from both sides

∴ -10x - 5y = 20

- Divide both sides by -5

∴ 2x + y = -4 ⇒ (2)

∵ The coefficient of x in equation (1) is 2

∵ The coefficient of x in equation (2) is 2

∴ The coefficients of x in the two equations are equal

∵ The coefficient of y in equation (1) is 1

∵ The coefficient of y in equation (2) is 1

∴ The coefficients of y in the two equations are equal

∵ The numerical term in equation (1) is 5

∵ The numerical term in equation (2) is -4

∴ The numerical terms are different

From the 2nd rule above

∴ No solution of the system of equations

No solution of the system of equations y = -2x + 5 and -5y = 10x + 20

Solve the inequality<br>-6p&lt;12 <br><br><br>Ah this is due by tomorrow
777dan777 [17]

-6p < 12    Divide -6 on both sides to get "p" by itself

\frac{-6p}{-6} < \frac{12}{-6}

p > -2


When you divide or multiply a negative number to both sides of the inequality, the sign (< , > , ≤ , ≥) is flipped.

In the last 10 years, the population of Indonesia has grown at a rate of 1.12% per year to 258,316,051. If this rate continues,
REY [17]

Answer:

288750006

Step-by-step explanation:

<u>Growth rate:</u>

  • 1.12% or 1.0112 times

<u>Current population:</u>

  • 258,316,051

<u>Predicted population after 10 years:</u>

  • 258,316,051*(1.0112)^10 = 288,750,006.168≈ 288,750,006 rounded

Write an equation that models the sequence 400, 200, 100, 50, ...
Julli [10]
You're starting at 400. Each time you're cutting in half. 

So the common ratio is 1/2 which means the equation is

\Large y = 400(1/2)^{x-1}

which is in the geometric sequence format. So the answer is choice D
