Solve this system of liner equations.separate the -x and y - values with a comma. 2x=96-14y 9x=40-14y

1 answer:

3 0

A) 2x=96-14y
B) 9x=40-14y
Rearranging algebraically

A) 2x +14y = 96
B) 9x +14y = 40

Multiplying equation A by -1
A) -2x -14y = -96 Then adding it to equation B
B) 9x +14y = 40
7x = -56
x = -8

2*-8 = 96 -14y
-16 -96 = -14y
-112 = -14y
y = 8

Given this function: f ( x )=−2cos(4 πx ) Find the following:

Neporo4naja [7]

Answer:

Period =½

Equation of midline, y=0

Maximum =2

Minimum=-2

Step-by-step explanation:

The given function is

$f(x) = - 2 \cos(4 \pi \: x)$

The period is given by:

$\frac{2\pi}{b} = \frac{2\pi}{4\pi} = \frac{1}{2}$

The equation of the midline is y=0 since there is no vertical shift

The amplitude of this function is 2 so the range is -2≤y≤2.

Hence the maximum value is 2 and minimum value is -2
