Answer:
x = 70
Step-by-step explanation:
45+2x-5 = 180
2x = 180 - 40
x = 140/2
x = 70
The quick way to do this is to multiply the bill by 1, mult. it again by 0.18, and then add the two results together.
Better and faster: Mult. the bill amount ($42.75) by 1.18:
1.18($42.75) = $50.45 (answer)
-3(3y-2x)+ 2(5x-4y)
-9y+6x+10x-8y
-17y+16x
So the answer is D.
Answer:
2. increasing when x > 0
the result of root is a positive number
and since there is no value of neg number in roots so it's increasing when x>0
plus in zero it self has a positive number (0,8)
but u cannot find either it's increasing or decreasing in zero bcoz in first derivative test
when x =0
y= not defined
