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

Answer:
9.2X + 13.4
Step-by-step explanation:
Combine like terms
Answer:
The balance after 1 is $7070.35.
Step-by-step explanation:
Compound continuous formula:
A=The final balance
P=Principal
r= interest rate.
Jason deposited $700.00 as principal for 1 year at a rate 1%, compounded continuously.
Here A=$700.00, t= 1 year, r=1%=0.01
=$7070.35
The balance after 1 is $7070.35.
15-20 hatchings because of 30 nests
Based on the information given, the most probable answer to this question is that the number of hatchlings would dependent on the number of nest there is. A sample of this should be able to amount to the populationThank you for your question. Please don't hesitate to ask in Brainly your queries.
