Let's solve your equation step-by-step.<span><span><span>6x</span>−<span>2<span>x4</span></span></span>=<span>12x</span></span><span><span><span>−<span>2<span>x4</span></span></span>+<span>6x</span></span>=<span>12x</span></span>
Step 1: Subtract 12x from both sides.<span><span><span><span>−<span>2<span>x4</span></span></span>+<span>6x</span></span>−<span>12x</span></span>=<span><span>12x</span>−<span>12x</span></span></span><span><span><span>−<span>2<span>x4</span></span></span>−<span>6x</span></span>=0</span>
Step 2: Factor left side of equation.<span><span><span>2x</span><span>(<span><span>−<span>x3</span></span>−3</span>)</span></span>=0</span>
Step 3: Set factors equal to 0.<span><span><span>2x</span>=<span><span><span>0<span> or </span></span>−<span>x3</span></span>−3</span></span>=0</span><span><span>x=<span><span>0<span> or </span></span>x</span></span>=<span>−1.44225</span></span>
Answer:<span><span>x=<span><span>0<span> or </span></span>x</span></span>=<span>−1.44225 This is the answer if its exponent. The other might be:</span></span>
Step 1: Simplify both sides of the equation.<span><span><span>6x</span>−<span>2<span>(<span>4x</span>)</span></span></span>=<span>12x</span></span><span>
Simplify: (Show steps)</span><span><span>−<span>2x</span></span>=<span>12x</span></span>
Step 2: Subtract 12x from both sides.<span><span><span>−<span>2x</span></span>−<span>12x</span></span>=<span><span>12x</span>−<span>12x</span></span></span><span><span>−<span>14x</span></span>=0</span>

Help please!!! Thank you
Anna11 [10]

Answer: ∠ABE=20°

Step-by-step explanation:

∵ AB=BC

∴ ΔABC is a isosceles triangle

∵ ∠A=30

∴ ∠C=30

∵ The interior angle sum of triangle is 180°

∵ ∠A+∠B+∠C=180

    30+∠B+30=180

           ∠B+60=180

                  ∠B=120 (∠ABC)

∵ ∠EBD+∠ABE+∠ABC=linear pair

∴∠EBD+∠ABE+∠ABC=180°

                  4x+2x+120=180

                        6x+120=180

                                6x=60

                                  x=10

∠ABE=2x=2(10)=20°

Hope this helps!! :)

Help. The problem is in the picture
inn [45]

Answer:

The answer to your question is y = 2/3x + 4

Step-by-step explanation:

Data

Equation     y = 2/3 x + 5

New line = ?

Process

Two lines are parallel if the have the same slope. The slope is the coefficient of the x.

1.- Get the slope of the original line

                y = 2/3x + 5

   slope = 2/3

2.- Two find the equation of a parallel line we need to point I will use (0, 4)

Use the point slope formula

               y - y1 = m(x - x1)

               y - 4 = 2/3(x - 0)

               y - 4 = 2/3 x

              y = 2/3x + 4
