Answer:
Step-by-step explanation:
the function is a cubic with a positive leading coeficient so enters the 3rd quadrant and exits on the 1st quadrant
Answer:
$4.25
Step-by-step explanation:
Let price of drink be x
price of tub y
You have 4x+2y=32.5 (1) and
x = y -3.5 (2)
Plug for x from (2) into (1):
4(y-3.5) + 2y = 32.5
4y -14 +2y = 32.5
6y = 14+32.5
y = (46.5)/6 = $7.75 the price of tub
x= y-3.5 = 7.75 - 3.5 = $4.25
X ≤ 40
the answer to the question
(3,4)(5,16)
slope = (16 - 4) / (5 - 3) = 12/2 = 6
y = mx + b
slope(m) = 6
use either of ur points (3,4)...x = 3 and y = 4
sub and find b, the y int
4 = 6(3) + b
4 = 18 + b
4 - 18 = b
-14 = b
so ur equation is : y = 6x - 14
