5 0

Answer: D) 13y^25 and 2y^25

Like terms involve the same variables, and each of those variables must have the same exponents.

Another example of a pair of like terms would be 5x^3y^2 and 7x^3y^2. Both involve the variable portion "x^3y^2" which we can replace with another variable, say the variable z. That means 5x^3y^2 becomes 5z and 7x^3y^2 becomes 7z. After getting to 5z and 7z, it becomes more clear we have like terms.

Answer: B) Infinitely many solutions; both equations are equivalent

==============================================================

Work Shown:

x+y = 4 ... start with the first equation

x + (-x+4) = 4 ... replace y with (-x+4)

x-x+4 = 4

0x+4 = 4

0+4 = 4

4 = 4 ... this is a true statement regardless of what x you pick

So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.

Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.

There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.

Solve the system of equations -5x – 2y = 13 and 3x-y = 12 by combining the equations
Ne4ueva [31]

Answer:

x=1 y =15

Step-by-step explanation:

hopefully correct

-5x-2y=13 (i)

3x-y=12

-y=12-3x

y=-12+3x (ii)

substitute ii into i

-5x-2(-12+3x)=13

-5x +24-6x=13

-11x=-11

x=1

substitute x into ii

y=-12+3(1)

y=15

.

. . x=1 and y =15
