Answer:

(1,-3)

x=1 y= -3

Step-by-step explanation:

Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)

so we have

(2x+2y)+(6x-2y)= -4+12

this simplifies to

8x=8

x=1

We know that x=1 and so we will plug this back into one of the two equations

2(1)+2y= -4

2+2y= -4

2y= -6

y= -3

Therefore the solution is (1,-3)

Answer:

2x+2y=-4

since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4

6x-2y=12

In this case this equation is incorrect.

Step-by-step explanation:

sorry if I'm incorrect

(please if I'm correct, I really need the brainliest)

Consider the two expressions 4b(b+1) and (2b+7)(2b-8). Compare their values if b=-3, b=-2, and if b=10. Is it true that for an v

noname [10]

Answer:

If b=-3 then the first expression is equal to 24 and the second expression is equal to -14.

If b=-2 then the first expression is equal to 8 and the second expression is equal to -36.

If b=10 then the first expression is equal to 440 and the second expression is equal to 324.

Yes, it is true.

Step-by-step explanation:

b=-3:

4b(b+1)=4(-3)(-3+1)=-12(-2)=24

(2b+7)(2b-8)=(2(-3)+7)(2(-3)-8)=(-6+7)(-6-8)=1(-14)=-14

b=-2:

4b(b+1)=4(-2)(-2+1)=-8(-1)=8

(2b+7)(2b-8)=(2(-2)+7)(2(-2)-8)=(-4+7)(-4-8)=3(-12)=-36

b=10:

4b(b+1)=4(10)(10+1)=40(11)=440

(2b+7)(2b-8)=(2(10)+7)(2(10)-8)=(20+7)(20-8)=27(12)=324
