Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299
Answer:
W is not a subspace.
Step-by-step explanation:
Notice that (-1,2,2) and (-1,5,3) are both elements of W. Because its x coordinate, x = -1, satisfy the condition |x| = 1.
but (-1,2,2) + (-1,5,3) = (-2,7,5) do not belongs to W. Because its first coordinate, x =-2, do not satisfy |x| = 1.

Answer:
-8 x2
1.25 x2
x2
Step-by-step explanation:
Like terms are those which have the same variable. For example x²= x ² but x³≠x² functions having the same variable are called like terms. Terms vary with the change in exponents.
-8 x2
1.25 x2
x2
These three are like terms because they have the same variable with the same exponent.
The following are not like terms. They are unlike terms each having a different variable with a different exponent.
5 yx2
-3.4 x3
4 x
5
Like terms -8 x2 1.25 x2 x2
Unlike terms :5 yx2 -3.4 x3 4 x 5
