Since line AB and line BC are congruent, you equal them to each, which will give the 'x' to substitute into line AB

$3x = 4x -2$

Subtract -4x from both sides of the equation.

$-x=-2$

Then divide -1 from both sides of the equation.

$x=2$

Then you do 3(2) which is 6.

The answer is B

AB and BC are congruent, so 4x-2= 3x, solve for x and you get x=2.

Y=3(x-2)+1 how can i graph this into slope intercept form

liraira [26]

Answer: y=3x--5

Step-by-step explanation: First simplify by distribution and lie terms to get:

y=3x-5

3 is your slope which means every time your y goes up three your x goes across one.

-5 is your y-intercept which means (0,-5) goes through your line

Is −4[3(x−7)] and 6(14−2x) equiviant

Paraphin [41]

Answer:

Yes.

Step-by-step explanation:

Set the equations equal to each other to determine their equality.

-4[3(x - 7)] = 6(14 - 2x)

Distribute the 3 and the 6 into their respective parenthesis.

-4[3x - 21] = 84 - 12x

Distribute the -4 into the brackets.

-12x + 84

Rearrange the equations.

84 - 12x = 84 - 12x

Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.
