Solve for x.<br> 5(x - 3) + 4(x + 3) = 3(x - 1)<br> What’s the answer ?

SSSSS [86.1K]

Answer:

x=0

Step-by-step explanation:

Solve for x.

5(x - 3) + 4(x + 3) = 3(x - 1)

Distribute

5x -15 +4x +12 = 3x-3

Combine like terms

9x -3 = 3x-3

Add 3 on each side

9x -3+3 = 3x-3

9x = 3x

Subtract 3x from each side

9x-3x = 3x-3x

6x =0

Divide by 6

6x/6 = 0/6

x=0

Eddi Din [679]

Answer:

63°

Step-by-step explanation:

The sum of all interior angles of a triangle = 180°

Therefore:

x + 96° + 21° = 180°

x + 117 = 180

Subtract 117 from each side

x = 180 - 117

x = 63°

Subtract the given function and indicate the domain of the difference

maxonik [38]

Answer:

The domain is $x\in (-\infty,\infty).$

Step-by-step explanation:

Given functions $f(x)=x^2+3x+1$ and $g(x)=2x^2-4x-1$

Subtract these two functions:

$f(x)-g(x)\\ \\=(x^2+3x+1)-(2x^2-4x-1)\\ \\=x^2+3x+1-2x^2+4x+1\\ \\=(x^2-2x^2)+(3x+4x)+(1+1)\\ \\=-x^2+7x+2$

Plot these difference on the coordinate plane (see attached diagram). This function is defined for all vlues of x, so the domain is $x\in (-\infty,\infty).$
