Answer:

x = 3

Step-by-step explanation:

5(2 - x) = 7x - 26

Distribute;

10 - 5x = 7x - 26

Add 5x to both sides;

10 = 12x - 26

Add 26 to both sides;

36 = 12x

Divide both sides by 12;

x = 3

Determine the amplitude or period as requested. Period of y = - 1/3 * sin 2x

Sedbober [7]

Answer:

$Period = \pi$

Step-by-step explanation:

Given

$y = -\frac{1}{3} * \sin(2x)$

Required

The period

A sine function is represented as:

$y =A \sin(Bx + C) + D$

Where

$Period = \frac{2\pi}{B}$

By comparing:

$y =A \sin(Bx + C) + D$ and $y = -\frac{1}{3} * \sin(2x)$

$B = 2$

So, we have:

$Period = \frac{2\pi}{2}$

$Period = \pi$

Hence, the period of the function is $\pi$

Geometry math question please help

denis-greek [22]

In parallelogram the opposite sides are equal. Therefore we have the equation:

$8a-4=6a+10\ \ \ |+4\\\\8a=6a+14\ \ \ |-6a\\\\2a=14\ \ \ |:2\\\\\boxed{a=7}$

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

$(18b-11)+(9b+2)=180\\\\(18b+9b)+(-11+2)=180\\\\27b-9=180\ \ \ |+9\\\\27b=189\ \ \ \ |:27\\\\\boxed{b=7}$

Answer:

c = a + b → c = 7 + 7 = 14

A. 14
