Which equation is true for x = –6 and x = 2?2x2 – 16x + 12 = 0
2x2 + 8x – 24 = 0
3x2 – 4x – 12 = 0
3x2 + 12x + 36 = 0

Answers

we know that

using a graph tool

let's proceed to graph each case to determine the roots

case 1) $2x^(2) - 16x + 12 = 0$

the roots are

$x1=0.8\ x2=7.2$ ------> is not the solution

see the attached figure N $1$

case 2) $2x^(2) +8x -24 = 0$

the roots are

$x1=-6\ x2=2$

see the attached figure N $2$ --------> is the solution

case 3) $3x^(2) - 4x - 12 = 0$

the roots are

$x1=-1.4\ x2=2.8$ ------> is not the solution

see the attached figure N $3$

case 4) $3x^(2) +12x +36 = 0$

the graph does not have x-intercepts

see the attached figure N $4$ ------> is not the solution

therefore

the answer is

the solution is

$2x^(2) +8x -24 = 0$

Second statement 2x2 + 8x – 24 = 0 Is true for the given conditions. When x = -6 2x2 + 8x – 24 = 0 Becomes 2(-6)2 + 8(-6) – 24 = 0 2(36) - 48 - 24 = 0 72 - 48 - 24 = 0 0 = 0 Which is true. When x = 2 2x2 + 8x – 24 = 0 Becomes 2(2)2 + 8(2) – 24 = 0 2(4) + 16 - 24 = 0 8 + 16 - 24 = 0 0 = 0 Which is true. So 2x2 + 8x – 24 = 0 will be answer.

X-2(x+10)=12 I have to find what x equals. Please help I am so confused

Answers

Answer:

X=24

Step-by-step explanation:

X-2(X+10)=20

x-4(x-10)=14

x-4x-40=14

3x-40=14

3x=54

3/54=24

x=24

How to solve x-y=102x-y=17

Answers

Is the equation x-y=10 and 2x-y=17?

Isolate the Y getting:
2x-17=y and x-10=y

Then bring the two equations together. Sub in the one equation for y.
2x-17 = x-10

The answer for x would be 7 (X=7)

Then pick an equation and sub in 7 for x to get your Y.

x-y=10
7-y=10
Subtract 7
-y=3
Divide the -1 from the y (Hopefully you learned why there's a 1 there)
y=-3

Answer is X=7 and Y=-3 or (7, -3)
