Which statements are true about the functions y
sin(x), y = cos(x), and y
tan(x)?
Both y = sin(x) and y tan(x) are increasing on the interval (0, 2). and y cos(a) is
decreasing on that interval.
The amplitudes of y = sin(x). y cos(x) and y tan(t) are 1.
The graphs of y = sin(I) and y cos(x) do not have midlines.
The domains of y = sin(x), y cos(x), and y = tan(a) are all real numbers.
The periods of y = sin(x) and y cos(x) are 27. and the period of y = tan(s) is er

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

hello,

as   long as they add up to 180 its correct.
