I'm pretty sure that these are lying in the space spanned by f and g: a)cos2x, <span>e)0. </span> Use common formulas to check it.
Answer:
One third 
Step-by-step explanation:
A year has 12 months, which means that 4 months would be 
, but since both the numerator and denominator can be divided by 4 this fraction can be simplified to
Answer:
-5/9
Step-by-step explanation:
Note. If the line is parallel, then the slope is shared. If the line is perpendicular (directly opposite), it means to flip the sign as well as the fraction.
The slope of line g is 9/5. This means that the slope of line h, (which is perpendicular to line g), would be the opposite, or -5/9
-5/9 is your answer.

Answer:
the answer would be 2(3-x)
Step-by-step explanation:
x would be the number that is given and since it says twice than 2 would be outside the parenthesis since the main equation would be inside the parenthesis
Answer:
-2/3
Step-by-step explanation:
We need to pick two points on the line.
(-2,0) and (1,-2)
We can use the slope formula
m = (y2-y1)/(x2-x1)
m = ( -2-0)/(1 - -2)
= (-2-0)/(1+2)
= -2/3
