Answer:
x=-8 and y=9
Step-by-step explanation:
rewrite the equations to x+2y=10,3x+4y=12
sub 2y from both sides x+2y-2y=10-2y
substitue x=10-2y in 3x +4y=12
3(-2y+10)+4y=12
distribute
add-30 to both sides
divide both sides by -2
y=9
sustitute 9 for y in -2y+10=x
x=-8
Answer:
x=16, y=-4
Step-by-step explanation:
-1(x-y=12)
x+7y=-20
-x+y=-12
x+7y=-20
8y=-32
y=-4
x-4=12
x=16
If you multiply 6 times 8 there are 48
Answer:convergent
Step-by-step explanation:
Given
Improper Integral I is given as
![I=\int_{-\infty}^{0}1000e^xdx](https://tex.z-dn.net/?f=I%3D%5Cint_%7B-%5Cinfty%7D%5E%7B0%7D1000e%5Exdx)
![I=1000=\int_{-\infty}^{0}e^xdx](https://tex.z-dn.net/?f=I%3D1000%3D%5Cint_%7B-%5Cinfty%7D%5E%7B0%7De%5Exdx)
integration of
is ![e^x](https://tex.z-dn.net/?f=e%5Ex)
![I=1000\times \left [ e^x\right ]^{0}_{-\infty}](https://tex.z-dn.net/?f=I%3D1000%5Ctimes%20%5Cleft%20%5B%20e%5Ex%5Cright%20%5D%5E%7B0%7D_%7B-%5Cinfty%7D)
![I=1000\times I=\left [ e^0-e^{-\infty}\right ]](https://tex.z-dn.net/?f=I%3D1000%5Ctimes%20I%3D%5Cleft%20%5B%20e%5E0-e%5E%7B-%5Cinfty%7D%5Cright%20%5D)
![I=1000\times \left [ e^0-\frac{1}{e^{\infty}}\right ]](https://tex.z-dn.net/?f=I%3D1000%5Ctimes%20%5Cleft%20%5B%20e%5E0-%5Cfrac%7B1%7D%7Be%5E%7B%5Cinfty%7D%7D%5Cright%20%5D)
![I=1000\times 1=1000](https://tex.z-dn.net/?f=I%3D1000%5Ctimes%201%3D1000)
so the integration converges to 1000 units
Answer:
y= 128, x=52
Step-by-step explanation:
The Sum of all the angles in a quadrilateral is 360.
y is 128 because both those angles are equal
the other 2 angles are also equal to each other.
360 - 128-128= 104
104/2 is 52
