Answer:
15x + 25 = y
Step-by-step explanation:
$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y
Answer:
sin a=3/5
cos a=4/5
Step-by-step explanation:
<u>sin</u> <u>A</u>
AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)
AB (squared)=16+9
AB (you must put a square root over AB)=25(remember 25 is now a square root)
AB=5
sin a=opposite/hypotenuse
=3/5
<u>cos A</u>
cos a=adjacent/hypotenuse
=4/5
