Which of the following statements best describes the graph of x + y = 2?

2 answers:

6 0

Ok, when a line intersects the x axis, y=0
when a line intersects the y axis, x=0

so A and B are false because neither A nor B are 0

C, the x and y coordinates have to add to 2, ya
x+y=2, duh

D. no, 4≠2 so nah

C is answer

I need to find the sum of this equation

Tresset [83]

Answer:

$\large\boxed{\dfrac{3s^2+19s-4}{(s-1)^2(s+5)}=\dfrac{3s^2+19s-4}{s^3+3s^2-9s+5}}$

Step-by-step explanation:

$s^2-2s+1=s^2-s-s+1=s(s-1)-1(s-1)=(s-1)(s-1)=(s-1)^2\\\\s^2+4s-5=s^2+5s-s-5=s(s+5)-1(s+5)=(s+5)(s-1)\\\\\text{Therefore}\ LCD\ \text{is}\ (s-1)^2(s+5).$

$\dfrac{3s}{s^2-2s+1}+\dfrac{4}{s^2+4s-5}=\dfrac{3s(s+5)}{(s-1)^2(s+5)}+\dfrac{4(s-1)}{(s-1)^2(s+5)}\\\\\text{use the distributive property}\\\\=\dfrac{(3s)(s)+(3s)(5)+(4)(s)+(4)(-1)}{(s-1)^2+(s+5)}=\dfrac{3s^2+15s+4s-4}{(s-1)^2(s+5)}\\\\=\dfrac{3s^2+19s-4}{(s-1)^2(s+5)}$

Does the following system of equations have a solution? If so, find one. If not, explain why not. 2x+y+z=4, x-y+3z=-2, -x+y+z=-2

Elena-2011 [213]

Answer:x=2, y=1, z=-1

Step-by-step explanation:

Given

2x+y+z=4----1

x-y+3z=-2----2

-x+y+z=-2----3

Add 2 & 3 we get

4z=-4

z=-1

Put value of z in 1 & 2

2x+y-1=4

2x+y=5----3

x-y+3(-1)=-2

x-y=1------4

add 3 & 4 we get

x=2

Put x & z in 1

y=1
