Solve for the indicated variable in the literal equation ​
ANTONII [103]

Answer:

x = \frac{y}{3} - \frac{5}{3}

Step-by-step explanation:

Given

y = 5 + 3x

Required

Solve for x

Subtract 5 from both sides

y-5 = 5 -5+ 3x

y-5 = 3x

Divide through by 3

\frac{y}{3} - \frac{5}{3} = x

x = \frac{y}{3} - \frac{5}{3}

What is the complete factorization of the polynomial below? X3-4x^2+x-4
OLga [1]

Answer:  (x - 4)(x - (i))(x + (i))

Step-by-step explanation:

This factoring job lends itself well to synthetic division.  Looking at the constant term, -4, I came up with several possible roots based upon -4:  {±1, ±2, ±4}.  I chose +4 as my first trial root.  Sure enough, there was a zero remainder, which indicated that 4 is a root of this polynomial and (x - 4) is a factor.  The coefficients of the trinomial quotients are 1   0   1, which indicates a quotient of x^2 + 1, which has the following roots:  x = +(i) and x = -(i)

So the complete factorization of the polynomial is (x - 4)(x - (i))(x + (i)).

nlexa [21]

Answer:

The answer is G. y=2x-2

Step-by-step explanation:

y+6=2(x+2)

First you multiply 2 by what is in the parenthesis

y+6=2x+4

Next you get y by itself by subtracting 6

y=2x+4-6

Simplify

y=2x-2
