2x+3y=11

4x+2y=10

multiple the top equation by -2

-4x-6y=-22

4x+2y=10

-4y= -12

y=3

then plug 3 for y so 2x+9=11

2x=2

x=1 and y=3

Y-3=2(x+1) please please help
Ivahew [28]

Answer:

y=2x+5

Step-by-step explanation:

distribute 2 to x and 1, do this by multiplying each.

you should get y-3=2x+2.

then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.

you then get the answer, y=2x+5.

What is the perimeter of the triangle expressed as a polynomial?
SVETLANKA909090 [29]
Sorry I couldn't find this sooner!

The perimeter of any polygon means the sum of all the lengths of its sides. In this case the sides are (5x - 2), (2x - 3), and (4x + 3). We can find the perimeter by adding all of these lengths up:

(5x - 2) + (2x - 3) + (4x + 3) 
= 5x - 2 + 2x - 3 + 4x + 3
=11x -2

Final Answer: B. 11x - 2
