Answer:
b)21
Step-by-step explanation:
f(-6) = 9 - 2 × (-6) = 9+12=21
Answer:
equation of a line is given by
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
where yi = 5, y2 = -2
and x1 = -2, x2 = 5
from the equation above
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
y -5 / X -(-2) ==> -2-5 / 5 - (-2)
y -5 / X + 2 ===> -7 /7
y - 5/ X + 2 ===> -1
cross multiply
y -5 ==> -1(X + 2)
y -5 ==> -x -2
collect like terms
y + x -3 = 0
or
y + X ===> +3
The common denominator of both fractions is 60.. You can convert 11/12 into 55/60 by multiplying both the numerator and denominator by 5, and you can also convert 7/20 into 21/60 by multiplying both the numerator and denominator by 3. 55/60-21/60= 34/60, simplified to 17/30.
Hope it helped!
You would take 180•15% to get 27 then you would subtract 180-27 to get 153. After you do the first you would do 200•20% to get 40 200-40=160 so the cheaper one would be the 180 because about 15% discount it’s 153 and 160>153
