Answer:
There is no solution.
Step-by-step explanation:
4y − 36 = −12x
3x + y = −9
Add 12x and 36 to both sides of the first equation.
12x + 4y = 36
3x + y = -9
Multiply both sides of the second equation by -4.
12x + 4y = 36
-12x - 4y = 36
Add the two equations.
0 = 72
Since 0 = 72 is a false statement, this system of equations has no solution.

Answer:
10¹⁸ ergs
Step-by-step explanation:
From the question,
Using the expression
M =
log(E/10¹³)................. Equation 1
Where M = Richter magnitude of earth quake, E = Energy released in ergs.
Given: M = 4.0
Substitute into equation 1 amd solve for E
4 =
log(E/10¹³)
Log(E/10¹³) = (4×5)/4
Log(E/10¹³) = 5
E/10¹³ = 10⁵
E = 10⁵×10¹³
E = 10⁵⁺¹³
E = 10¹⁸ ergs
Step-by-step explanation:
The given equations are :
y=-x+2 ....(1)
y = -4x +7 ....(2)
From equation (1) and (2)
-x+2 = -4x +7
Taking like terms together
-x+4x=7-2
3x = 5
x = 1.667
Put the value of x in equation (1)
y=-(1.667)+2
y = 0.333
The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.
