3 + -4x = 5(x +6)

Re-order the terms:

3 + -4x = 5(6 + x)
3 + -4x = (6 . 5 + x . 5)
3 + -4x = (30 + 5x)

Solving:

3 + -4x = 30 + 5x

Solving for variable "x"

Move all terms containing "x" to the left, all the other terms to the right.

Add "-5x" to each side of the equation.
3 + -4x + -5x = 30 + 5x + -5x

Combine like terms: 
-4x + -5x = -9x
3 + -9x = 30 +5x + -5x

Combine like terms: 
5x + -5x = 0
0 + -9x = 30 +0
3 + -9x = 30

Add "-3" to each side of the equation.
3 + -3 + -9x = 30 + 3

Combine like terms: 
3 + -3 = 0
0 + -9x = 30 + -3
-9x = 30 + -3

Combine like terms: 
30 + -3 = 27
-9x = 27

Divide each side by "-9".
x = -3

Simplifying:
x = -3

3−(4x−5)+6

=3+−4x+5+6

=3+−4x+5+6

=(−4x)+(3+5+6)

=−4x+14

The boxed definition of absolute value states that |a|=-a if a is a negative number. Explain why |a| is always nonnegative, even
Temka [501]

Final answer:

Since absolute values determine the distance between the number and the value whether the value is positive or negative. As distance is always positive.

Thus, |a| is always nonnegative, even though |a|=-a for negative values of a.

Step-by-step explanation:

Step 1

It is said that |a| is always nonnegative even though even though |a|=-a for negative values of a.

Step 2

This is because by the definition of an absolute value, any real number inside an absolute value symbol || will always be positive.

When a river​ flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flo
strojnjashka [21]

The figure is missing. There are several problems with same wording but different numbers

Here, we can use:

  • Horizontal distance: 258 feet

  • Vertical fall: 56.0 feet

Answer:

  • Slope = 56.0 ft / 258 ft ≈ 0.217

Explanation:

The <em>slope</em> measures how the rate of change of the vertical distance (vertical fall) with respect to the horizontal distance.

There are several forms to express this with words, which represent the same formula. Here are some of them:

  • Slope = rise / run
  • Slope = vertical change / horizontal change
  • Slope = change in y / change in x
  • Slope = Δy / Δx
  • Slope = (y₂ - y₁) / (x₂ - x₁)

As said, all those forms mean the same; they are equivalent.

Here, we have vertical fall = 56.0 feet, and horizontal distance = 258 feet, and by specifications of the problem (in the hint) the slope must be positive. Thus, you get:

  • Slope = vertical fall / horizontal distance = 56.0 feet / 258 feet ≈ 0.217

Is y=2/3 x^2-7 linear or nonlinear
borishaifa [10]

Answer:

Nonlinear

Explanation:

y=2/3 x^2-7 is nonlinear because it is not in slope intercept form.

Also, x² automatically means it is nonlinear because this is the formula for a parabola when graphed. Parabolas are nonlinear.

The parabola also doesn't continue in a straight or nearly straight line. That is what linear is.
