Solve the equations help

Mathematics
1 answer:
Leni [432]3 years ago
5 0

Answer:

First equation x=2, Y=9, Second Eq, x=2, y=1

Step-by-step explanation:

X+Y=11

2X-Y=-5 by substitution Y=11-X

So, 2x-(11-x)=-5, 2x-11+x=-5, 3x=6, x=2. Thus, Y=11-2=9

2x+y=5

3x-2y=4

so, y=5-2x

Thus, 3x-2(5-2x)=4

3x-10+4x=4, 7x=14, x=2, Thus, Y=5-2(2)= 1

What does the constant term in the polynomial 4x2 + 9 represent?
shusha [124]

Answer:

The constant in the polynomial is 9. A constant number is a number that does not change during the equation. This equation is 4x² + 9. Since you are just adding 9 the number of 9 does not change. If you were multiplying 9 it would not be a constant anymore because it does not stay the same throughout the equation.

Hope This Helps :)

A. My best friends, whose name is Laura, is in law school.

You know this because, if you were to take out the part in between the commas, the sentence would still make sense. It just adds additional detail.
