the cosine is a cyclical function, so it cycles through from 0 all the way to the left and from 0 all the way to the right, nonstop, so its domain is (-∞, +∞), namely all real numbers.
Answer:
7,7
Step-by-step explanation:
A vertex should be connected, so 7 as the x makes the most sense
Answer:
y = - 3x + 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 5 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (6, 8 ) into the partial equation
8 = - 18 + c ⇒ c = 8 + 18 = 26
y = - 3x + 26 ← equation of parallel line
Answer:
x = -20
Step-by-step explanation:
You move the 14 with the 6, since it is addition, it changes symbols ( from + to - ), so it'd be;
x = -6 - 14, since you are subtracting a negative number, you are technically adding them.
