Solve 3(x - 4) = 11x

Ivanshal [37]

Answer:

$x = \frac{-3}{2}$

Step-by-step explanation:

3(x - 4) = 11x

Expand the brackets:

3x - 12 = 11x

Subtract 3x from both sides to isolate the -12:

3x - 12 = 11x

3x - 3x - 12 = 11x - 3x

-12 = 8x

8x = -12

Divide both sides by 8:

$\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\$

Simplify fraction:

$x = \frac{-12}{8}$

$x = \frac{-12 \div 4}{8 \div 4}\\x = \frac{-3}{2}$

Hope this helps!

Which graph represents the piecewise function? x+3 if x<0 2x if x ≥ 0

kolbaska11 [484]

Answer:

Graph 1 will be the correct one.

Step-by-step explanation:

We are given the piece wise function defined as

f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0

The first part of the function does not include x = 0.

And, this is in slope-intercept form.

So, slope is 1 i.e. tan Ф = 1, ⇒ Ф = 45°.

And it has y-intercept at (0,3).

So, the conditions are shown in graphs 1 and 3.

Now, the second part of the function equation passes through origin {As the equation is f(x) = 2x}

So, only graph 1 matches both the conditions.

Therefore, graph 1 will be the correct one. (Answer)
