Answer:it has one and only one solution.
Step-by-step explanation:
The given system of equations is expressed as
4x - 5y = 24 - - - - - - - - - - - - -1
2x + 3y = -10 - - - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 1 and equation 2 by 2. It becomes
4x - 5y = 24
4x + 6y = - 20
Subtracting, it becomes
- 11y = 44
Dividing the left hand side and the right hand side of the equation by
- 11, it becomes
- 11y/- 11 = 44/- 11
y = - 4
Substituting y = - 4 into equation 2, it becomes
2x + 3 × - 4 = -10
2x - 12 = - 10
2x = - 10 + 12
2x = 2
Dividing the left hand side and the right hand side of the equation by
2, it becomes
2x/2 = 2/2
x = 1
1/5 goes into 37 185 times:
37 / (1/5) = 37*(5/1)=185
Answer:
a) 10/27 or 0.37037
b) -8/7
Step-by-step explanation:
a) Enter x=-5 into both equations and divide h(-5)/g(-5). That yields 10/27 or 0.37037037037 . . .
b) g(x) cannot be 0 (can't divide by 0. That would occur if x = -8/7, so it (-8/7) is not in the domain.
<span> lets say integrand is e^(y/x):
∫(x = 0 to 1) ∫(y
= 0 to x^2) e^(y/x) dy dx
= ∫(x = 0 to 1) xe^(y/x)
= ∫(x = 0 to 1) x(e^x - 1) dx
= ∫(x = 0 to 1) (xe^x - x) dx
= (xe^x - e^x) - (1/2)x^2
= 1/2. </span>
