Reorder the terms:

6 + 14x = 15x

Solving

6 + 14x = 15x

Solving for variable 'x'.

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

Add '-15x' to each side of the equation.

6 + 14x + -15x = 15x + -15x

Combine like terms: 14x + -15x = -1x

6 + -1x = 15x + -15x

Combine like terms: 15x + -15x = 0

6 + -1x = 0

Add '-6' to each side of the equation.

6 + -6 + -1x = 0 + -6

Combine like terms: 6 + -6 = 0

0 + -1x = 0 + -6

-1x = 0 + -6

Combine like terms: 0 + -6 = -6

-1x = -6

Divide each side by '-1'.

x = 6

Simplifying

x = 6

Find all complex solutions of 11x^2-5x+2=0. If there is more than one solution separate them with commas.

sergejj [24]

Answer:

No real solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

11x2−5x+2=0

For this equation: a=11, b=-5, c=2

11x2+−5x+2=0

Step 1: Use quadratic formula with a=11, b=-5, c=2.

−b±√b2−4ac

−(−5)±√(−5)2−4(11)(2)

2(11)

5±√−63

The angle of elevation to the bottom of the rainbow is 42°

Explanation:

Given that the bottom of a double rainbow is going over a tree that is 18 feet tall and you're standing 20 feet from the tree.

We need to determine the angle of elevation to the bottom of the rainbow.

Let us use the trigonometric ratios to determine the angle of elevation.

Thus, we have,

$tan \ \theta=\frac{opp}{adj}$

where opp = 18 and adj = 20 and we need to determine the angle.

Substituting the values, we have,

$tan \ \theta=\frac{18}{20}$

Dividing the values, we have,

$tan \ \theta=0.9$

Taking $tan^{-1$ on both sides of the equation, we get,

$\theta=tan^{-1}(0.9)$

Thus, we get,

$\theta=41.99^{\circ}$

Rounding off to the nearest degree, we get,

$\theta=42^{\circ}$

Hence, the angle of elevation to the bottom of the rainbow is 42°

kondaur [170]

A: to find rate of change you take the smallest rate:

2 bushels/$15 and divide both by 2 so that you get 1 bushel and $15/2=$7.5, therefor 1 bushel/$7.50.

B:The current year is at 2 bushels/$16 or 1 bushel/$8, which is $.50 more than the previous year.
